Leukemia: Causes, Symptoms, Types, Treatment and Cost in India

Leukemia is a cancer of the blood-forming tissues, mainly the bone marrow. It is the most common cancer in children, and it also affects many adults, particularly older people. For families in Africa, the Middle East, Central Asia and South Asia, a diagnosis of leukemia can be frightening, especially where specialised blood cancer units, intensive chemotherapy support and bone marrow transplant facilities are limited. The hopeful news is that treatment has advanced remarkably. Most children with acute lymphoblastic leukemia are now cured, many adults with chronic myeloid leukemia live a near-normal life on daily tablets, and stem cell transplantation and newer therapies such as CAR-T cell therapy offer cure even for high-risk disease. India has become a leading destination for this care.

What is Leukemia?

Blood cells are made in the bone marrow, the soft tissue inside the bones. Normally the marrow produces red blood cells (to carry oxygen), white blood cells (to fight infection) and platelets (to stop bleeding) in a controlled way. In leukemia, abnormal white blood cells (blasts or leukemic cells) multiply out of control, crowd out the healthy cells and spill into the blood. This leads to anaemia, infections and bleeding.

Types of Leukemia

Leukemia is classified by how fast it progresses (acute or chronic) and by the type of white cell affected (lymphoid or myeloid):

• Acute Lymphoblastic Leukemia (ALL): the most common childhood cancer, peaking between 2 and 5 years of age, but also seen in adults.
• Acute Myeloid Leukemia (AML): more common in adults and older people; a subtype called acute promyelocytic leukemia (APL) is highly curable but needs urgent treatment.
• Chronic Myeloid Leukemia (CML): mainly affects adults; caused by the Philadelphia chromosome (BCR-ABL gene) and very well controlled with tablets.
• Chronic Lymphocytic Leukemia (CLL): the most common leukemia in older adults in Western countries, less common in Asia and Africa; often slow-growing.

Rarer types include hairy cell leukemia and juvenile myelomonocytic leukemia.

Causes and Risk Factors

In most patients there is no clear cause. Leukemia results from changes in the genes of developing blood cells. Known risk factors include:

• Previous chemotherapy or radiotherapy for another cancer
• High-dose radiation exposure
• Exposure to benzene and certain industrial chemicals, including in petroleum industries
• Smoking, which increases the risk of AML
• Genetic conditions such as Down syndrome and Fanconi anaemia
• Blood disorders such as myelodysplastic syndrome that can turn into AML
• Virus infection: HTLV-1 is linked to adult T-cell leukemia, seen in parts of Africa, the Caribbean, the Middle East (notably Iran) and Japan

Leukemia is not contagious and in most cases is not inherited.

Symptoms of Leukemia

• Tiredness, weakness, pale skin and breathlessness due to anaemia
• Frequent or severe infections and persistent fever
• Easy bruising, small red spots on the skin (petechiae), nose or gum bleeding, or heavy periods
• Bone or joint pain, especially in children (which can be mistaken for rheumatic or sickle cell pain)
• Swollen lymph nodes in the neck, armpits or groin
• Swelling or fullness in the abdomen from an enlarged spleen or liver
• Unexplained weight loss and night sweats

Chronic leukemias may cause no symptoms and are often discovered on a routine blood test.

Warning Signs That Need Urgent Care

• High fever in a person with low white cell counts or on chemotherapy
• Heavy bleeding that does not stop, or blood in vomit, urine or stool
• Severe headache, confusion, seizures or vision changes
• Severe breathlessness or chest pain

How is Leukemia Diagnosed?

• Complete blood count (CBC) and peripheral smear: often the first clue, showing abnormal white cells, low haemoglobin or low platelets.
• Bone marrow aspiration and biopsy: confirms the diagnosis and percentage of blasts.
• Flow cytometry (immunophenotyping): identifies the exact type of leukemia cell.
• Cytogenetics and FISH: look for chromosome changes such as the Philadelphia chromosome.
• Molecular tests (PCR, next-generation sequencing): detect mutations like FLT3, NPM1 and BCR-ABL that guide treatment and predict outcome.
• Lumbar puncture: checks for leukemia in the spinal fluid, especially in ALL.
• Measurable residual disease (MRD) testing during treatment to measure response.

Treatment Options for Leukemia

Treatment depends on the type of leukemia, genetic features, age and general health. It is delivered by haemato-oncologists in specialised units with infection-controlled rooms, round-the-clock blood bank support and intensive care.

Chemotherapy

Acute leukemias are treated with intensive chemotherapy in phases: induction (to achieve remission), consolidation (to destroy remaining cells) and, for ALL, maintenance for about two years with mostly oral medicines. Children with ALL are treated on established protocols with excellent cure rates. Older or frail adults with AML may receive gentler treatment such as venetoclax with azacitidine.

Targeted Therapy

• Tyrosine kinase inhibitors (imatinib, dasatinib, nilotinib) for CML and Philadelphia-positive ALL. Affordable generic versions made in India have transformed CML care.
• All-trans retinoic acid (ATRA) and arsenic trioxide for APL, often curing the disease without heavy chemotherapy.
• FLT3 and IDH inhibitors for AML with these mutations.
• BTK inhibitors (ibrutinib, acalabrutinib) and venetoclax for CLL.

Immunotherapy and CAR-T Cell Therapy

Monoclonal antibodies such as blinatumomab and inotuzumab are used for relapsed ALL. CAR-T cell therapy, in which the patient's own immune cells are modified to attack leukemia, is now available in India, including indigenously developed CAR-T products, at a much lower cost than in Western countries.

Bone Marrow (Stem Cell) Transplant

A bone marrow transplant replaces diseased marrow with healthy stem cells, usually from a matched sibling, an unrelated donor or a half-matched (haploidentical) family member. It is recommended for high-risk or relapsed acute leukemia. Indian transplant centres have extensive experience with haploidentical transplants, which means almost every patient can find a donor within the family.

Cost of Leukemia Treatment in India

Indicative starting prices at JCI/NABH-accredited hospitals in Delhi/NCR are:

The final cost depends on the type of leukemia, the treatment protocol, complications such as infections, blood product requirements and the length of hospital stay. Contact Satyug Healthcare at +91-8860606766 / +91-9910655125 (WhatsApp) for a free medical opinion and cost estimate.

Recovery and Living with Leukemia

Acute leukemia treatment is intensive, and patients usually stay in hospital for 4 to 6 weeks during induction. International patients should plan to stay in India for 3 to 6 months for chemotherapy or a transplant, and about 3 months after a transplant for close monitoring. ALL maintenance and CML tablets can usually be taken at home, with periodic visits or teleconsultations.

• Infection prevention: hand hygiene, safe cooked food, clean water and avoiding crowds during low blood counts.
• Regular monitoring: blood counts, bone marrow tests and BCR-ABL levels (for CML).
• Vaccination: transplant patients are re-vaccinated after recovery.
• Long-term follow-up: children who survive leukemia are checked for growth, heart, hormone and learning effects.
• Emotional support for patients and families is an important part of care.

There is no proven way to prevent most leukemias, but avoiding tobacco and benzene exposure and seeking early medical attention for unexplained symptoms help.

Frequently Asked Questions

Is leukemia curable?

Many types are. Most children with ALL are cured, APL has very high cure rates, and many adults with AML can be cured with chemotherapy and transplant. CML is usually controlled long-term with tablets, and some patients can eventually stop treatment under close supervision.

Who can be a bone marrow donor?

A fully matched brother or sister is ideal. If none is available, a half-matched parent, child or sibling can donate (haploidentical transplant), or an unrelated donor can be searched in registries.

Is donating bone marrow painful or risky?

Most donors today give stem cells from the blood after a few days of growth-factor injections, a process similar to blood donation. It is safe, and donors return to normal activity within days.

How long does leukemia treatment take?

Intensive treatment for acute leukemia takes about 6 months; ALL maintenance continues for about 2 years. CML tablets are usually taken long-term.

Can my child go to school during treatment?

During intensive phases, children are usually kept away from school to avoid infections. Most return to school during the maintenance phase with their doctor's approval.

What is CAR-T cell therapy?

It is a personalised treatment in which a patient's T-cells are collected, genetically engineered to recognise leukemia cells, and infused back. It is used mainly for relapsed or resistant B-cell ALL and certain lymphomas.

Can I continue treatment in my home country?

Maintenance therapy and CML tablets can usually be continued at home with local blood tests and regular video consultations with your Indian specialist.

What reports should I send for a cost estimate?

Please share your CBC, peripheral smear, bone marrow report, flow cytometry, cytogenetic and molecular reports, and a brief treatment history. Our team will obtain opinions from top haemato-oncologists within 48 hours.
