Leukemia: Types, Symptoms, Causes, Treatment

Leukemia is a type of cancer that begins in the blood-forming tissues, primarily the bone marrow and lymphatic system. Unlike many cancers that start with solid tumors, leukemia affects the production and function of blood cells. The bone marrow, which normally produces healthy white blood cells, red blood cells, and platelets, starts producing abnormal white blood cells that do not function properly. These abnormal cells multiply rapidly, crowding out healthy cells, and preventing the blood from doing its essential work of carrying oxygen, fighting infections, and clotting.

There are different forms of leukemia, each with its own pace and characteristics. Some are aggressive and develop quickly, while others progress more slowly. The disease affects people of all ages, from young children to the elderly, making it one of the most widely studied cancers in the world. Despite its seriousness, medical advancements have significantly improved survival rates and treatment outcomes over the past few decades.

Leukemia is often described as a silent disease because many of its early symptoms mimic common illnesses such as the flu or fatigue from daily life. This makes it challenging to detect without medical testing. That’s why awareness and understanding are crucial—both for individuals who may be at risk and for families who may have loved ones affected by the disease.

Importance of Awareness and Early Detection

Early detection of leukemia can make a significant difference in treatment outcomes. Many patients who receive a diagnosis in the early stages have a better chance of responding well to therapy and achieving remission. Unfortunately, because symptoms like tiredness, fever, and frequent infections are easily overlooked, leukemia often goes undiagnosed until it reaches a more advanced stage.

Awareness campaigns and education play an essential role in changing this trend. By knowing the signs and encouraging regular health checkups, especially for those with family histories of blood cancers, individuals can improve their chances of early intervention.

Furthermore, raising awareness about leukemia helps reduce stigma and fear surrounding the disease. Many patients and families struggle with emotional distress after a diagnosis, but community support, medical guidance, and shared knowledge can ease this burden. Society benefits when we promote early testing and greater understanding of how leukemia works and how it can be managed.

Types of Leukemia

Acute Lymphocytic Leukemia (ALL)

Acute lymphocytic leukemia, or ALL, is the most common form of cancer in children, although it can also occur in adults. It begins in the bone marrow, where immature white blood cells called lymphoblasts are produced in large numbers. These lymphoblasts crowd out healthy blood cells and quickly spread to other organs such as the liver, spleen, and lymph nodes.

The term “acute” means that the disease progresses rapidly, and without treatment, it can become life-threatening within weeks or months. Fortunately, children diagnosed with ALL today have high survival rates thanks to advances in chemotherapy and targeted therapy. In adults, however, the prognosis is often less favorable, requiring more aggressive treatment approaches.

Treatment usually involves several phases: induction (to bring the leukemia into remission), consolidation (to kill remaining cells), and maintenance (to prevent relapse). In some cases, stem cell transplants are necessary. Despite being an aggressive cancer, early diagnosis and modern therapies have made ALL one of the most treatable forms of leukemia in children.

Acute Myeloid Leukemia (AML)

Acute myeloid leukemia (AML) is a fast-growing type of leukemia that primarily affects older adults, although it can occur in children. AML develops when immature white blood cells called myeloblasts build up in the bone marrow. Unlike ALL, which affects lymphocytes, AML impacts the myeloid cells that normally develop into red blood cells, white blood cells, and platelets.

The symptoms of AML appear suddenly and may include frequent infections, easy bruising, fatigue, and shortness of breath. Because the disease progresses quickly, immediate treatment is necessary. Standard treatment often involves intensive chemotherapy, and in some cases, a bone marrow transplant may be recommended.

AML is known for its complexity because there are several subtypes, each requiring different treatment strategies. Genetic testing often helps doctors determine which subtype a patient has, guiding personalized treatment plans. Survival rates vary depending on age, overall health, and specific genetic mutations present in the cancer cells.

Chronic Lymphocytic Leukemia (CLL)

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in adults, especially in people over the age of 60. Unlike acute leukemias, CLL progresses slowly and may not cause symptoms for years. It begins in the bone marrow, where abnormal lymphocytes are produced. These cells look mature but are functionally defective.

Many patients discover they have CLL during routine blood tests before experiencing any symptoms. When symptoms do occur, they may include swollen lymph nodes, frequent infections, weight loss, and night sweats. Because the disease advances slowly, some patients do not require immediate treatment. Instead, doctors may recommend a “watch and wait” approach, monitoring the disease closely until intervention is necessary.

When treatment is required, options include chemotherapy, targeted therapy, and immunotherapy. Advances in targeted drugs have dramatically improved outcomes for CLL patients, allowing many to live long and relatively healthy lives even with the disease.

Chronic Myeloid Leukemia (CML)

Chronic myeloid leukemia (CML) is characterized by the uncontrolled growth of myeloid cells in the bone marrow. It typically progresses in three phases: chronic, accelerated, and blast crisis. Most patients are diagnosed in the chronic phase, where the disease is more manageable.

One of the most significant breakthroughs in leukemia treatment came with the development of targeted therapies for CML. Drugs known as tyrosine kinase inhibitors (TKIs) specifically target the genetic abnormality (the Philadelphia chromosome) that drives the disease. For many patients, these drugs have transformed CML from a life-threatening illness into a manageable chronic condition.

Patients with CML can often live for decades with proper treatment, maintaining a good quality of life. Regular monitoring through blood tests is essential, as the disease can progress to more aggressive stages if not controlled.

Rare Types of Leukemia

In addition to the four main types of leukemia, there are several rare forms. These include hairy cell leukemia, prolymphocytic leukemia, and large granular lymphocytic leukemia. While less common, these diseases still require specialized diagnosis and treatment.

Hairy cell leukemia, for example, is a slow-growing cancer where abnormal lymphocytes appear “hairy” under a microscope. It progresses gradually and often responds well to treatment, with many patients living long lives after diagnosis.

Though rare, these types highlight the importance of precise medical testing and expert care. Misdiagnosis or delayed treatment can have serious consequences, which is why specialized care centers play a vital role in treating unusual forms of leukemia.

Causes and Risk Factors

Genetic Factors

While the exact cause of leukemia is not always clear, genetics plays a significant role. Mutations in DNA can lead to uncontrolled cell growth in the bone marrow. Some people inherit genetic predispositions that increase their risk, while in others, mutations develop randomly during their lifetime.

Certain inherited conditions, such as Down syndrome, Li-Fraumeni syndrome, and Fanconi anemia, are known to increase the risk of leukemia. Families with a history of blood cancers may also have higher risks. Genetic testing can sometimes identify these predispositions, allowing for closer monitoring of at-risk individuals.

However, it’s important to note that having a genetic risk factor does not guarantee that someone will develop leukemia. Many people with these conditions never develop the disease, while others with no family history or known risk still receive a diagnosis.

Environmental Factors

Exposure to certain environmental toxins and chemicals can contribute to leukemia risk. For example, long-term exposure to benzene—a chemical found in gasoline and industrial settings—has been linked to higher leukemia rates. Radiation exposure, whether from medical treatments or environmental accidents, can also increase risk.

Workers in industries involving pesticides, rubber manufacturing, or chemical plants may be at greater risk due to prolonged contact with harmful substances. Similarly, people living near areas with high environmental pollution may face increased risks.

It’s worth noting, however, that not everyone exposed to these factors develops leukemia. Environmental exposure simply raises the likelihood but does not guarantee disease development. Preventive measures such as workplace safety regulations and limiting exposure to harmful chemicals play a crucial role in reducing risks.

Lifestyle and Other Risks

Lifestyle factors may also contribute to leukemia risk. Smoking, for example, has been linked to certain types of leukemia, particularly AML. Poor diet, lack of exercise, and chronic stress can weaken the immune system, potentially influencing disease development.

Age is another major risk factor. While leukemia can occur at any age, some types are more common in specific age groups. For example, ALL is more common in children, while CLL and AML primarily affect older adults.

Previous cancer treatments, such as chemotherapy or radiation therapy, may increase the chance of developing leukemia later in life. This is known as secondary leukemia. Although rare, it highlights the complex relationship between medical treatments and long-term health risks.

Symptoms of Leukemia

Early Symptoms to Watch For

The early symptoms of leukemia are often subtle and can easily be mistaken for everyday health problems. Persistent fatigue, unexplained fever, frequent infections, and night sweats are among the most common early warning signs. Because these symptoms resemble those of flu or other common illnesses, many people delay seeking medical attention.

Other early symptoms include swollen lymph nodes, small red spots on the skin (petechiae), and frequent nosebleeds. These occur because leukemia interferes with normal blood cell production, reducing the body’s ability to fight infections and form clots.

Catching these signs early can make a significant difference in treatment outcomes. Regular medical checkups and blood tests are critical, especially for people at higher risk.

Advanced Symptoms of the Disease

As leukemia progresses, symptoms become more pronounced. Severe fatigue, unintentional weight loss, bone pain, and frequent bruising are common in advanced stages. Some patients experience enlargement of the spleen or liver, leading to abdominal discomfort.

Anemia, caused by a shortage of healthy red blood cells, is also common. This leads to shortness of breath, weakness, and pale skin. In some cases, advanced leukemia may affect the central nervous system, causing headaches, vision problems, or seizures.

At this stage, immediate treatment becomes crucial to prevent life-threatening complications. Without medical intervention, advanced leukemia can progress rapidly.

Differences in Symptoms Between Types

Different types of leukemia can present unique symptoms. For example:

• ALL often causes bone pain and is more likely to spread to the brain and spinal cord.

• AML may cause gum swelling and skin lesions.

• CLL progresses slowly, with symptoms like fatigue and swollen lymph nodes developing over the years.

• CML may remain asymptomatic in its early chronic phase but lead to fever, night sweats, and weight loss in advanced stages.

Recognizing these differences helps doctors make accurate diagnoses and ensures patients receive the right treatment plan.

Diagnosis of Leukemia

Blood Tests and Bone Marrow Biopsy

The first step in diagnosing leukemia usually involves a simple blood test. If abnormal levels of white blood cells, red blood cells, or platelets are detected, doctors may suspect leukemia. However, blood tests alone cannot confirm the diagnosis.

A bone marrow biopsy is often performed to confirm leukemia. In this procedure, a small sample of bone marrow is extracted, usually from the hip bone, and examined under a microscope. This test helps doctors determine the type of leukemia and its severity.

Though the procedure can be uncomfortable, it provides crucial information that guides treatment decisions. Without it, doctors would struggle to determine the exact nature of the disease.

Imaging and Genetic Testing

In some cases, imaging tests such as CT scans or MRIs may be used to check if leukemia has spread to other parts of the body. Lumbar punctures can also determine whether the disease has reached the central nervous system.

Genetic testing plays an increasingly important role in leukemia diagnosis. Many types of leukemia are linked to specific genetic mutations, such as the Philadelphia chromosome in CML. Identifying these mutations not only confirms diagnosis but also helps tailor treatment.

Targeted therapies, for example, are often designed to attack specific genetic abnormalities, making genetic testing essential in modern leukemia care.

Importance of Accurate Diagnosis

Leukemia is not a one-size-fits-all disease. Accurate diagnosis ensures patients receive the most effective treatment for their specific condition. Misdiagnosis or delays in diagnosis can lead to ineffective treatment and worsened outcomes.

Doctors consider a variety of factors when diagnosing leukemia, including age, overall health, genetic profile, and type of leukemia. Because treatment options vary widely—from watchful waiting in CLL to aggressive chemotherapy in AML—accurate diagnosis is a life-saving step.

Treatment Options for Leukemia

Chemotherapy

Chemotherapy is one of the most common and effective treatments for leukemia. It uses powerful drugs to kill cancer cells or stop them from multiplying. Unlike surgery, which removes localized tumors, chemotherapy targets cancer cells throughout the body, making it especially suitable for blood cancers like leukemia.

In leukemia treatment, chemotherapy often begins with an induction phase, where the goal is to destroy as many leukemia cells as possible and achieve remission. This is usually followed by a consolidation phase, designed to eliminate remaining hidden cancer cells, and a maintenance phase, which helps prevent relapse.

Chemotherapy can be given orally in pill form, intravenously through a vein, or injected into the spinal fluid if cancer is suspected in the central nervous system. Because chemotherapy is powerful, it also affects healthy cells, leading to side effects like hair loss, fatigue, nausea, and lowered immunity.

Despite its intensity, chemotherapy remains a cornerstone of leukemia treatment. Over the years, researchers have refined drug combinations, dosing schedules, and supportive care measures to reduce side effects and improve patient outcomes. Many leukemia patients today achieve long-term remission or even full recovery thanks to chemotherapy advancements.

Radiation Therapy

Radiation therapy uses high-energy beams, such as X-rays, to kill cancer cells. It is less common in leukemia than in solid tumors, but it still plays an important role in specific cases. For example, radiation may be used if leukemia cells accumulate in certain areas, such as the spleen, brain, or spinal cord.

In preparation for a bone marrow or stem cell transplant, total body irradiation may also be used to wipe out cancer cells and suppress the immune system, allowing transplanted cells to grow more effectively.

Although radiation therapy is localized, it can cause side effects such as skin irritation, fatigue, and nausea, depending on the area treated. Long-term risks include damage to healthy tissues, but modern techniques have significantly reduced these risks.

Targeted Therapy

Targeted therapy represents a major breakthrough in leukemia treatment. Unlike traditional chemotherapy, which attacks both cancerous and healthy cells, targeted therapy focuses specifically on genetic mutations or proteins that drive leukemia growth.

One of the best-known examples is the use of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia (CML). These drugs, such as imatinib, block the activity of the abnormal Philadelphia chromosome, effectively halting the cancer’s progression. Many patients with CML who once faced limited options now live long, healthy lives with daily targeted therapy pills.

Targeted therapy is also used in other types of leukemia, often in combination with chemotherapy or immunotherapy. Its precision reduces damage to healthy cells, resulting in fewer side effects compared to traditional treatments.

Immunotherapy

Immunotherapy harnesses the body’s immune system to recognize and fight leukemia cells. One of the most exciting developments is CAR-T cell therapy, where doctors collect a patient’s T-cells, genetically reprogram them to attack cancer, and then reintroduce them into the body. This approach has shown remarkable success, especially in children with relapsed acute lymphocytic leukemia (ALL).

Other immunotherapy approaches include monoclonal antibodies, which are lab-made proteins that bind to leukemia cells and mark them for destruction, and checkpoint inhibitors, which release the brakes on immune cells so they can attack cancer more effectively.

While immunotherapy is still evolving, it has given hope to patients who previously had limited treatment options. Its ability to provide long-term remission, even in resistant cases, marks it as one of the most promising frontiers in leukemia care.

Stem Cell Transplantation

Stem cell transplantation, also known as a bone marrow transplant, is one of the most aggressive but potentially curative treatments for leukemia. It involves replacing diseased bone marrow with healthy stem cells, either from the patient (autologous transplant) or a donor (allogeneic transplant).

Before transplantation, high-dose chemotherapy or radiation is used to destroy diseased marrow. Then, healthy stem cells are infused into the bloodstream, where they travel to the bone marrow and start producing new, healthy blood cells.

This treatment carries risks, including infections, graft-versus-host disease (in donor transplants), and organ complications. However, for many patients, especially those with high-risk or relapsed leukemia, stem cell transplantation offers the best chance for long-term remission or cure.

Managing Side Effects of Treatment

Physical Side Effects

Leukemia treatments are powerful, and side effects are almost inevitable. Chemotherapy, for instance, often causes nausea, vomiting, mouth sores, fatigue, and hair loss. Radiation therapy may cause localized skin irritation and fatigue. Immunotherapy can sometimes trigger flu-like symptoms, fevers, or allergic reactions.

A particularly concerning side effect is the suppression of the immune system. Because treatments often reduce white blood cell counts, patients become highly vulnerable to infections. Preventive antibiotics, regular monitoring, and careful hygiene practices are crucial to protecting patients during this vulnerable time.

Other long-term effects may include infertility, secondary cancers, or organ damage, depending on the treatment received. While these risks can be daunting, medical teams work closely with patients to minimize harm and provide supportive care throughout treatment.

Emotional and Psychological Impact

Living with leukemia is not just a physical challenge—it also takes a heavy emotional toll. The uncertainty of the disease, the stress of prolonged hospital stays, and the fear of relapse can lead to anxiety and depression. Children and their families, in particular, face enormous psychological strain.

Counseling, therapy, and participation in support groups can be immensely helpful. Talking openly about fears and experiences helps patients and families feel less isolated. Many hospitals now offer specialized mental health support alongside medical care, recognizing that emotional well-being is an essential part of recovery.

Supportive Care and Rehabilitation

Supportive care focuses on improving quality of life during and after treatment. This may include pain management, nutritional guidance, physical therapy, and blood transfusions.

For example, patients with anemia may receive red blood cell transfusions to improve energy levels, while platelet transfusions can help prevent bleeding. Nutritionists often design personalized diets to help patients regain strength, while physical therapists assist with regaining mobility and fitness after long hospital stays.

Rehabilitation continues even after treatment ends. Regular follow-ups, exercise programs, and lifestyle adjustments are crucial to maintaining long-term health. Supportive care ensures patients are not only surviving but also thriving after leukemia treatment.

Living with Leukemia

Lifestyle Changes and Nutrition

A leukemia diagnosis often forces patients to reevaluate their lifestyles. Eating a nutrient-rich diet, staying physically active (as much as possible), and avoiding tobacco or excessive alcohol can make a significant difference.

Nutrition plays a particularly important role. Patients undergoing treatment may have weakened immune systems, making them more vulnerable to foodborne illnesses. Doctors often recommend a “neutropenic diet,” which emphasizes well-cooked foods, pasteurized products, and avoiding raw or undercooked items.

Exercise, though sometimes difficult during treatment, helps maintain muscle strength, reduce fatigue, and improve mood. Gentle activities such as walking, stretching, and yoga can be beneficial without overwhelming the body.

Coping Mechanisms and Support Groups

Coping with leukemia requires resilience and support. Many patients find comfort in joining support groups, whether in person or online. Sharing experiences with others who understand the challenges can reduce feelings of isolation.

Some patients turn to meditation, mindfulness, or spiritual practices to find peace and strength. Journaling, creative outlets, and spending time with loved ones also provide emotional relief.

Family and caregivers play a crucial role, too. Their encouragement, patience, and understanding help patients face treatment with greater confidence and hope.

Long-Term Monitoring

Even after successful treatment, leukemia patients require lifelong monitoring. Follow-up appointments, regular blood tests, and occasional bone marrow biopsies are essential to detect any signs of relapse early.

Some patients remain in remission for years, while others experience relapses that require additional treatment. Doctors often create personalized survivorship plans that outline follow-up schedules, health screenings, and recommended lifestyle adjustments.

The goal of long-term monitoring is not just to prevent recurrence but also to ensure patients maintain overall well-being. With advances in medical care, many people with leukemia now live long, fulfilling lives, but vigilance remains key.

Leukemia in Children vs. Adults

Differences in Types and Prognosis

Leukemia affects both children and adults, but the types and outcomes can differ significantly. In children, the most common form is acute lymphocytic leukemia (ALL), while in adults, acute myeloid leukemia (AML) and chronic leukemias are more prevalent.

Children with ALL often respond better to treatment compared to adults, with survival rates exceeding 85% in many cases. Adults, particularly older individuals, may face more complications due to weaker immune systems, other health conditions, and less tolerance for aggressive treatments.

The biology of leukemia cells also differs between children and adults, influencing how the disease behaves and how it responds to therapy.

Treatment Approaches

Treatment strategies for children and adults vary based on age, overall health, and type of leukemia. Children often receive higher doses of chemotherapy because their bodies can tolerate more aggressive treatments. Adults, particularly seniors, may require adjusted doses or alternative therapies to minimize risks.

Stem cell transplantation is more commonly considered for adults, especially in high-risk or relapsed cases. Children, however, often achieve long-term remission with chemotherapy alone.

Psychological and social support also differ. Children may need help keeping up with school, maintaining friendships, and coping with disrupted routines, while adults may struggle with career interruptions, financial stress, and family responsibilities.

Survival Rates and Outlook

The survival rates for leukemia have improved dramatically over the past decades. Children with ALL have some of the highest success rates, while outcomes for adult AML remain more challenging. Chronic leukemias like CLL and CML are often managed as long-term conditions rather than cured outright, allowing many adults to live normal lives.

Age plays a major role in prognosis. Younger patients generally recover faster and have fewer complications, while older patients may face lower survival rates. However, ongoing research and new therapies are helping to close this gap, offering hope for all age groups.

Advances in Leukemia Research

Latest Medical Breakthroughs

Leukemia research is advancing rapidly, leading to new treatments and improved outcomes. Breakthroughs in genomics have helped doctors understand the genetic mutations driving different types of leukemia, leading to more personalized therapies.

For example, targeted drugs like TKIs for CML or FLT3 inhibitors for certain types of AML have revolutionized treatment approaches. Researchers are also exploring combination therapies that use multiple strategies to overcome drug resistance.

Advancements in immunotherapy, particularly CAR-T cell therapy, have provided hope for patients with relapsed or treatment-resistant leukemia. Clinical trials continue to test new immune-based treatments with promising results.

Role of Clinical Trials

Clinical trials are at the heart of leukemia research. They allow patients access to cutting-edge therapies not yet widely available. Many patients who participate in trials benefit from treatments that later become standard care.

These trials also help doctors refine existing therapies, reduce side effects, and improve long-term outcomes. By enrolling in trials, patients not only improve their own chances but also contribute to scientific progress that benefits future generations.

Hope for the Future

The future of leukemia treatment is brighter than ever. With ongoing research into gene editing, personalized medicine, and advanced immunotherapies, doctors are moving closer to finding cures and improving the quality of life for patients worldwide.

What was once considered a fatal diagnosis is now, in many cases, a manageable or even curable disease. Continued investment in research, patient education, and access to modern therapies ensures that the outlook for leukemia patients will keep improving.

Prevention and Risk Reduction

Can Leukemia Be Prevented?

Unlike many other cancers, leukemia does not have a clear prevention strategy. This is because it often arises from genetic mutations that cannot be controlled or predicted. However, research suggests that reducing exposure to certain risk factors can lower the chances of developing the disease.

For example, avoiding prolonged exposure to harmful chemicals like benzene (found in gasoline and some industrial products) may reduce risk. Similarly, minimizing unnecessary radiation exposure, whether from medical imaging or environmental sources, can also be beneficial.

Genetic factors are beyond personal control, but individuals with a strong family history of leukemia or inherited conditions that predispose them to cancer can benefit from regular health checkups and genetic counseling. While prevention may not be guaranteed, early detection through monitoring plays a critical role in reducing complications and improving outcomes.

Practical Steps for Lowering Risks

While leukemia cannot always be prevented, adopting a healthier lifestyle supports a stronger immune system and overall well-being, which may lower risks indirectly. Practical steps include:

• Quit smoking: Tobacco increases the risk of acute myeloid leukemia (AML).

• Healthy diet: A balanced diet rich in fruits, vegetables, whole grains, and lean proteins strengthens the body’s defense systems.

• Regular exercise: Staying active helps maintain immune function and reduces chronic disease risks.

• Safe workplace practices: Workers in industries with chemical exposure should follow strict safety measures, including protective gear and ventilation systems.

• Limit alcohol consumption: Excessive alcohol intake weakens the immune system and affects overall health.

• Regular checkups: Especially important for individuals with family histories of leukemia or past cancer treatments.

Though not foolproof, these lifestyle choices can help reduce risks and prepare the body to better handle illness if it arises.

Global Statistics and Survival Rates

Current Numbers Worldwide

Leukemia is among the most common cancers worldwide, with hundreds of thousands of new cases diagnosed each year. According to the World Health Organization (WHO) and Global Cancer Observatory (GLOBOCAN), leukemia accounts for about 3% of all cancer cases globally.

In the United States alone, the American Cancer Society estimates over 60,000 new leukemia cases each year. The disease affects both genders, though slightly more men are diagnosed than women. Children account for a smaller proportion of cases, but leukemia remains the most common childhood cancer, particularly acute lymphocytic leukemia (ALL).

Globally, leukemia survival rates vary greatly depending on healthcare access, early diagnosis, and treatment availability. Wealthier nations tend to have higher survival rates due to advanced medical infrastructure and wider access to therapies. In contrast, developing countries face challenges such as late diagnoses, limited treatment resources, and high treatment costs.

Trends and Improvements in Survival

Over the last few decades, survival rates for leukemia have improved dramatically. For instance:

• ALL in children now has survival rates of 85–90% in developed countries.

• CML patients often live decades with targeted therapy, turning it into a chronic condition rather than a fatal one.

• AML and CLL survival rates are improving thanks to advances in chemotherapy, targeted therapy, and stem cell transplantation.

These improvements are largely due to breakthroughs in targeted therapy, immunotherapy, and genomic research. In addition, better supportive care—such as antibiotics, transfusions, and psychological support—has significantly improved patients’ quality of life during treatment.

Despite these advances, survival rates remain lower for older adults and patients in countries with limited healthcare resources. Bridging this gap is one of the greatest challenges in global leukemia care.
