What Is Acute Lymphoblastic Leukaemia (ALL)?
Acute Lymphoblastic Leukaemia is a type of cancer that affects the blood and bone marrow. Acute lymphoblastic leukaemia is also known as acute lymphocytic leukaemia. It develops rapidly and requires prompt medical attention. The disease begins in the bone marrow, which is the soft tissue inside your bones. This is where new blood cells are made.
In ALL, the body starts producing a large number of immature white blood cells called lymphoblasts. These cells are not fully developed, so they can't do the job of normal white blood cells, which is to fight infections. As more and more of these abnormal cells are made, they begin to crowd out the healthy cells in the bone marrow.
This crowding causes three main problems in the body:
- Anaemia (Low Red Blood Cells): When there are fewer healthy red blood cells, the body does not get enough oxygen. It leads to symptoms like tiredness, weakness, dizziness, and shortness of breath. Everyday activities can become harder because the body lacks the energy it usually has.
- Infections (Low White Blood Cells): With fewer functioning white blood cells, the immune system becomes very weak. It means that even minor infections can become serious. Patients may experience frequent fevers, sore throats, or other signs of infection that are hard to control.
- Bleeding or Bruising (Low Platelets): Platelets help the blood clot. When platelet levels drop, it becomes easier to bruise and bleed. People with ALL may notice bleeding gums, nosebleeds, or small red spots on the skin. Even minor cuts may take longer to stop bleeding.
Types of Acute Lymphoblastic Leukaemia
ALL is not one single disease. Doctors categorize it into different types based on the type of white blood cell that has developed into cancer. Understanding the type of ALL helps doctors choose the proper treatment.
- B-cell ALL: This is the most common type of ALL, especially in young children. It starts in a kind of white blood cell called B lymphocytes. Most children with leukaemia have this form, and it usually responds well to standard treatments like chemotherapy.
- T-cell ALL: This type begins in T lymphocytes, another kind of white blood cell. T-cell ALL is less common than B-cell ALL, but it can grow faster. It is often seen in older children, teenagers, and young adults. T-cell ALL may need more aggressive treatment.
- Philadelphia Chromosome-Positive ALL (Ph+ ALL): This is a special genetic form of ALL, often found in adults. It is caused by a mutation that creates a faulty chromosome called the Philadelphia chromosome. Patients with Ph+ ALL usually need both chemotherapy and targeted drugs like tyrosine kinase inhibitors. These medicines work by attacking the specific gene mutation.
Who Gets ALL?
ALL can happen to people of all ages, but it is most common in children. In fact, it is the most common type of cancer in children under age five. However, teenagers, young adults, and older adults can also develop this disease.
Risk Factors for ALL
Doctors do not always know what causes ALL, but certain factors can increase a person's risk of developing ALL. These include:
- Previous chemotherapy or radiation therapy used to treat another cancer can slightly increase the risk of developing ALL later in life.
- Genetic conditions, such as Down syndrome, can also raise the risk. Children with this condition have a higher chance of developing leukaemia.
- A family history of leukaemia may suggest a small inherited risk, though this is not common.
- High exposure to radiation, such as from nuclear accidents or repeated medical scans at a young age, may also raise the risk.
Still, most people who develop ALL do not have any known risk factors. It often appears without warning.
Common Symptoms of Acute Lymphoblastic Leukaemia
The signs of ALL can appear suddenly. Because the disease spreads quickly, symptoms can worsen rapidly. Recognizing these early signs is crucial so that treatment can begin as soon as possible.
- Fatigue and Weakness: One of the first and most common symptoms is extreme tiredness. People may feel weak even after resting. It occurs due to anaemia characterized by a low number of red blood cells.
- Fever or Frequent Infections: Recurring fevers and infections that don't improve easily may be a sign that the immune system is not working. It is due to a shortage of healthy white blood cells.
- Easy Bruising or Bleeding: Some people notice unexplained bruises, bleeding gums, or frequent nosebleeds. It is caused by low platelet counts, which prevent normal blood clotting.
- Bone or Joint Pain: Pain in the arms, legs, or joints is common, especially in children. It happens when the bone marrow becomes overcrowded with abnormal cells.
- Swollen Lymph Nodes: Swelling in the neck, armpits, or groin may be due to enlarged lymph nodes. These swellings are usually painless but can be a sign that leukaemia cells have spread.
- Pale Skin: Individuals with ALL may appear paler than usual due to anaemia. It is due to a lack of red blood cells, which carry oxygen to the body.
- Shortness of Breath: Feeling out of breath, especially after light activity, can also be linked to anaemia. The body is not getting enough oxygen, and breathing may feel harder.
If you or someone you care for has any of these symptoms for more than a few days, it is essential to see a doctor. A simple blood test can show if something is wrong. Early detection makes a significant difference in the effectiveness of treatment. The sooner ALL is found, the better the chances of curing it.
Diagnosis and Testing for Acute Lymphoblastic Leukaemia (ALL)
Diagnosing ALL involves several steps. Doctors use a mix of physical exams, lab tests, and imaging to confirm the disease and determine its type. Getting an accurate diagnosis is very important because it guides the entire treatment plan.
- Initial Medical Evaluation: The doctor will begin by asking about your symptoms, such as fatigue, fever, or bleeding, and how long they have lasted. A physical examination will be conducted to assess for signs such as swollen lymph nodes, pale skin, or an enlarged liver or spleen. If leukaemia is suspected, the doctor will promptly order blood tests and other diagnostic tests to confirm the diagnosis.
- Complete Blood Count (CBC): A CBC is usually the first test done when ALL is suspected, and it checks the number of red blood cells, white blood cells, and platelets. In people with ALL, the test often shows a very high white blood cell count and low levels of red cells and platelets. The presence of immature white blood cells (lymphoblasts) in the blood can strongly suggest leukaemia.
- Blood Smear and Bone Marrow Test: Pathologists examine blood smears under a microscope to look at the size and shape of the blood cells and to check for blasts. To confirm ALL, a bone marrow aspiration and biopsy are done, where a sample of bone marrow is taken from the hip bone. This test measures the number of abnormal blast cells in the bone marrow and helps confirm a diagnosis of leukaemia.
- Immunophenotyping and Flow Cytometry: Immunophenotyping is a specialized laboratory test that identifies the exact type of leukaemia by examining the proteins on the surface of the leukaemia cells. This test helps doctors determine whether the ALL is of B-cell or T-cell type, which is crucial for selecting the appropriate treatment. Flow cytometry is the technique used to perform this test quickly and accurately.
- Cytogenetic and Molecular Testing: These tests examine changes in the chromosomes and genes of leukaemia cells, such as the Philadelphia chromosome. Finding these genetic changes helps predict how the leukaemia will behave and whether targeted therapies will be needed. Some of the standard tests include FISH (Fluorescence In Situ Hybridization), PCR (Polymerase Chain Reaction), and karyotyping.
- Lumbar Puncture (Spinal Tap): This test checks if the leukaemia has spread to the central nervous system, especially the brain or spinal cord. A small amount of cerebrospinal fluid is removed using a thin needle in the lower back and then tested for leukaemia cells. It is typically performed after the diagnosis is confirmed and before treatment commences.
- Imaging Tests: Imaging procedures such as X-rays, ultrasounds, CT scans, or MRIs may be performed to examine swollen organs or lymph nodes. These scans help the doctor assess the extent to which the disease has spread and determine whether any other organs are affected.
Treatment Phases for Acute Lymphoblastic Leukaemia (ALL)
Treatment for acute lymphoblastic leukaemia happens in several carefully planned stages. Each phase has a specific goal and timeline. The treatment plan depends on your age, type of ALL, risk level, and overall health. However, the general approach is similar for most patients.
Doctors follow a step-by-step method to destroy leukaemia cells, prevent the cancer from returning, and rebuild the body's immune system.
Phase 1: Induction Therapy
The first phase of treatment is called induction therapy. The primary goal is to eliminate as many leukaemia cells as possible and achieve remission from the disease.
- This phase begins immediately after diagnosis and typically lasts approximately 4 to 6 weeks.
- Intensive chemotherapy drugs are given through a vein (IV), by mouth, or sometimes into the spinal fluid.
- Patients may need to stay in the hospital during this time, especially if they are at high risk of infection or have low blood counts.
- After this phase, doctors check your bone marrow to determine if the leukaemia has been eradicated. If there are fewer than 5% leukaemia cells in the marrow, it means the patient is in remission.
Phase 2: Consolidation Therapy (Also Called Intensification)
Even after remission, some leukaemia cells may remain in the body. So, the second phase, called consolidation or intensification, is started.
- This phase is usually more intense than induction and lasts for several months.
- Potent chemotherapy drugs are used to destroy any remaining leukaemia cells.
- In some cases, targeted therapy or immunotherapy may also be added, especially in patients with the Philadelphia chromosome or other high-risk genetic variations.
- The goal of this phase is to prevent leukaemia from returning.
Phase 3: Central Nervous System (CNS) Prophylaxis
Acute lymphocytic leukaemia can sometimes spread to the brain and spinal cord. Even if there are no signs of leukaemia in these areas, doctors often give treatment to protect the central nervous system (CNS). This step is called CNS prophylaxis.
- It can happen during both the induction and consolidation phases.
- Doctors use chemotherapy drugs injected directly into the spinal fluid through a lumbar puncture. This is called intrathecal chemotherapy.
- Sometimes, radiation therapy to the brain may also be used, although it's less common today—especially in children—due to long-term side effects.
Phase 4: Maintenance Therapy
Once the leukaemia is under control, the patient moves to the final stage: maintenance therapy.
- This phase uses lower doses of chemotherapy to keep the leukaemia from returning.
- It typically lasts 2 to 3 years, but the treatment is significantly less intense than the earlier phases.
- Most of the drugs can be taken at home in pill form, although occasional hospital visits are still needed.
- Regular blood tests help monitor the patient's response and check for signs of relapse.
Additional Treatments for Some Patients
In some instances, especially when the leukaemia is high-risk or doesn't respond well to early treatment, other therapies may be needed.
- Targeted Therapy: Some patients receive drugs that attack specific genetic mutations in leukaemia cells. These are often used for Philadelphia chromosome-positive acute lymphoblastic leukaemia (ALL).
- Immunotherapy: Treatments like CAR-T cell therapy help the immune system recognize and destroy leukaemia cells.
- Stem Cell Transplant: In some high-risk cases, a bone marrow or stem cell transplant is done after intensive chemotherapy. It helps rebuild the immune system using healthy cells from a donor.
Treatment Options Available in India for Acute Lymphoblastic Leukaemia (ALL)
India has become one of the top destinations for affordable and advanced cancer treatment. Many international patients come to India for treatment of acute lymphoblastic leukaemia due to the world-class care, experienced doctors, and significantly lower costs compared to Western countries.
Hospitals across India adhere to international treatment guidelines and provide both standard and advanced therapies for all types of acute lymphoblastic leukaemia.
Chemotherapy
Chemotherapy is the main form of treatment for ALL in India, just like in other parts of the world.
- It is given in phases: induction, consolidation, CNS prophylaxis, and maintenance.
- Most Indian hospitals utilize drug protocols approved by the National Cancer Institute (NCI) and the World Health Organization (WHO).
- Both children and adults receive personalized chemotherapy plans based on their risk level and type of leukaemia.
- Chemotherapy may be given orally, intravenously (IV), or directly into the spinal fluid (intrathecal).
Many hospitals also offer day-care chemotherapy services, so patients do not need to stay overnight unless necessary.
Targeted Therapy
Some patients, especially adults, have Philadelphia chromosome-positive (Ph+ ALL). These patients benefit from targeted therapy.
- Indian hospitals offer medications such as imatinib, dasatinib, and nilotinib, which are tyrosine kinase inhibitors (TKIs).
- These medicines target the genetic abnormality and help destroy leukaemia cells more effectively.
- Targeted drugs are often given along with chemotherapy to improve outcomes.
Generic versions of these drugs are available in India at significantly lower costs, making treatment more affordable.
Immunotherapy (CAR-T Cell Therapy)
CAR-T cell therapy is a cutting-edge treatment for patients who don't respond to standard therapies or relapse.
- India is now offering CAR-T cell therapy at leading cancer hospitals, such as the Fortis Memorial Research Institute in Gurgaon.
- This treatment utilizes the patient's own immune cells, which are modified to target and destroy leukaemia cells.
- While still expensive, it is more accessible in India compared to countries such as the United States or the United Kingdom.
- CAR-T therapy is mainly used in advanced or relapsed cases of ALL.
Radiation Therapy
Radiation therapy is not the first choice of treatment for acute lymphoblastic leukaemia, but it may be used in exceptional cases.
- It may be given to the brain or spinal cord if leukaemia has spread to these areas.
- Radiation may also be used before a stem cell transplant in some high-risk patients.
- Indian hospitals utilize the latest technology, including IMRT and IGRT, to deliver precise radiation with fewer side effects.
Stem Cell or Bone Marrow Transplant
Doctors recommend a stem cell transplant for patients with high-risk or relapsed ALL.
- India has several top-tier bone marrow transplant centres with high success rates.
- The transplant involves replacing the damaged bone marrow with healthy stem cells from a donor.
- Both matched-related donor and unrelated donor transplants are available in India.
- The cost of a transplant in India is significantly lower than in the US or Europe.
Many Indian hospitals maintain their own stem cell registries or are linked with international ones for donor matching.
Supportive Care Services
Indian hospitals also offer strong supportive care, which is essential during ALL treatment.
- Blood transfusions and antibiotics are available 24/7 to manage low counts and infections.
- Nutritionists help with meal planning to support recovery.
- Psychologists and counsellors offer emotional support to both patients and families.
- Infection control in Indian hospitals is taken seriously, especially in specialized cancer centres.
Hospitals also offer accommodations and language services for international patients, making it easier to stay during treatment.

Recovery, Follow-Up, and Life After Treatment for ALL
Finishing treatment for acute lymphoblastic leukaemia (ALL) is a significant milestone. But the journey doesn't end there. Recovery takes time, and follow-up care is critical. With the right support and lifestyle changes, many patients go on to live healthy lives.
Here's what patients and families should know about the recovery phase and life after treatment.
The Recovery Phase
After completing chemotherapy or other treatments, your body needs time to heal and regain strength.
- Fatigue is normal. Many patients feel tired for weeks or months. Rest and good nutrition help speed up recovery.
- The immune system is still weak. Even when treatment ends, your immune system may take time to rebuild. This means avoiding infections, practising good hygiene, and staying away from crowded places when needed.
- Hair regrowth and appetite return. If you lose hair during treatment, it usually starts growing back a few months after chemo ends. Your appetite may also improve gradually.
- Emotional ups and downs are common. Patients often feel anxious or scared about relapse. It's normal. Support from loved ones and counselling can be very helpful.
Importance of Follow-Up Care
Follow-up care is a key part of surviving leukaemia. It helps detect relapse early and manage side effects.
- Regular check-ups: You will need frequent visits to your oncologist—first monthly, then every few months, and eventually yearly.
- Blood tests and bone marrow tests: Doctors will monitor for signs of relapse or long-term effects
- Managing side effects: Some treatments can affect your heart, liver, or other organs. Follow-up tests help keep track.
- Vaccinations and preventive care: You may need to repeat childhood vaccines or take special ones because of immune suppression.
- Fertility and growth monitoring: Children and young adults may need long-term monitoring for development and fertility issues.
Even if you feel healthy, never skip your follow-up appointments. They are vital for long-term wellness.
Dealing with Long-Term Side Effects
Some patients experience side effects even months or years after treatment has been completed. These are known as "late effects."
- Cognitive challenges: Some children and teenagers may experience difficulties with memory or concentration. Schools and therapists can help manage this.
- Heart or bone problems: Certain chemo drugs may affect heart health or bone strength. Regular scans and medications can help.
- Emotional well-being: Anxiety, depression, or PTSD can affect survivors. Support groups, therapy, and mindfulness can make a big difference.
- Second cancers: Rarely, individuals treated for ALL may develop a different type of cancer years later. This is why lifelong follow-up is essential.
With early action and support, most side effects can be managed effectively.
Nutrition and Healthy Lifestyle After ALL
Healthy habits play a crucial role in maintaining the body's strength after leukaemia.
- Eat balanced meals with fruits, vegetables, whole grains, and proteins.
- Stay hydrated and avoid junk food, alcohol, or smoking.
- Exercise gently—even light walking helps boost energy and mood.
- Get enough sleep to help the body repair itself.
- Limit exposure to infections until your immune system is fully back to normal.
Emotional Support for Survivors and Families
Finishing treatment can evoke a range of mixed emotions, including relief, fear, hope, and worry.
- Survivors may feel pressure to "go back to normal," but healing takes time.
- Parents and caregivers may struggle with anxiety or burnout.
- Support groups, survivor networks, and professional counselling offer great comfort.
Talking about your feelings helps. You're not alone—millions of survivors around the world have walked this path and come out stronger
