What Rishi Kapoor's Story Can Help Us Understand About Leukemia

What his family said

Rishi Kapoor died on April 30, 2020, in a Mumbai hospital. He was 67. Al Jazeera reported the family's statement, which said he died after two years of treatment for leukemia, carried out across two continents.

That is the whole of the public medical record. His family did not name a type of leukemia, and neither will we. He was born on September 4, 1952, into one of Indian cinema's best-known families, and made his debut as a child in Mera Naam Joker.

The useful thing his story leaves behind is a question most people cannot answer: what does the word "leukemia" actually describe?

Not one disease

NCI puts it plainly. Leukemia is a broad term for cancers of the blood cells. Which leukemia a person has depends on two things: which kind of blood cell turned cancerous, and whether it grows quickly or slowly.

Blood cells are made in bone marrow, the spongy tissue inside large bones. Marrow produces two main lines. Lymphoid cells become the lymphocytes of the immune system. Myeloid cells become red cells, platelets, and most white cells.

Cross those two lines with fast and slow, and you get the four main leukemias:

• Acute lymphoblastic leukemia (ALL) — fast, lymphoid.
• Acute myeloid leukemia (AML) — fast, myeloid.
• Chronic lymphocytic leukemia (CLL) — slow, lymphoid.
• Chronic myeloid leukemia (CML) — slow, myeloid.

There are rarer ones too, such as hairy cell leukemia. NCI keeps a separate treatment summary for each, because they are separate illnesses.

Why the type changes everything

The gap between these diseases is wide, and SEER, the federal cancer surveillance program, shows it in the numbers.

For leukemia overall, the American Cancer Society projects about 67,790 new United States cases in 2026 and about 23,910 deaths; SEER republishes those counts. SEER's measured five-year relative survival, for people diagnosed between 2016 and 2022, is 68.6 percent. Split it apart and the average dissolves.

AML: about 22,720 new cases projected by the Society, five-year relative survival 33.4 percent. CLL: about 22,760 projected cases — almost identical in number — five-year relative survival 90.2 percent. CML sits at 71.1 percent and ALL at 73.2 percent. Every survival percentage here comes from SEER's own follow-up of people diagnosed between 2016 and 2022.

Two people can both be told they have leukemia and be facing entirely different situations. This is why "which type?" is the first question worth asking, and why an overall leukemia statistic tells an individual almost nothing.

Those figures are group averages drawn from people diagnosed years ago. They describe populations. They do not describe any one reader.

How it is found, and what treatment looks like

There is no screening test. NCI states that it has no PDQ evidence-based information on screening for leukemia, and none on preventing it. Almost every case starts with symptoms or an unexpected blood count.

Diagnosis usually runs in this order: a blood count showing something off, then a bone marrow biopsy — a needle sample from the hip bone — then laboratory tests on those cells to identify the exact type and the genetic changes inside it. Our page on how cancer is diagnosed explains what those steps involve.

Treatment follows the type. Acute leukemias are treated urgently, usually with intensive chemotherapy aimed at clearing the marrow so healthy cells can regrow. Chronic leukemias can move slowly enough that some people are monitored for years before anything starts. CML is now often managed with a daily tablet that blocks the specific abnormal protein driving it.

Some people are offered a stem cell transplant, which replaces diseased marrow with healthy blood-forming cells from a donor. Our explainer on stem cell transplant covers what that involves and why it is not right for everyone.

Signs that warrant a blood test

Every one of these has ordinary causes far more often than it has a serious one. What raises the question is a cluster, or one that persists for two or three weeks.

• Tiredness that rest does not touch, sometimes with paleness or breathlessness on mild exertion.
• Bruising from knocks you do not remember, or small flat red dots on the skin.
• Bleeding gums, frequent nosebleeds, or a cut that keeps oozing.
• Repeated infections, or fevers with no obvious source.
• Night sweats that soak the sheets, or weight loss you did not intend.
• Swollen glands in the neck, armpit, or groin, or aching in the bones.

A full blood count is a cheap, fast test. If a cluster like this has gone on, asking for one is reasonable.

What to keep in perspective

• Kapoor's family named leukemia and nothing more. Any account that assigns him a subtype is going beyond the record.
• Two years of treatment says nothing about anyone else's course. Leukemia timelines range from days to decades.
• Age at diagnosis is not destiny. NCI notes leukemia is most common in adults over 55, and is also the most common cancer in children under 15 — where outcomes for ALL are very different from those in older adults.
• A slow-growing leukemia is not a mild one, and watchful monitoring is a treatment decision, not an absence of care.
• None of the symptoms above means leukemia. They mean the blood is worth looking at.
