ON THIS PAGE: You will find information about the estimated number of people who will be diagnosed with leukemia each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors, and no 2 people with cancer are the same. Use the menu to see other pages.

Every person is different, with different factors influencing their risk of being diagnosed with this cancer and the chance of recovery after a diagnosis. It is important to talk with your doctor about any questions you have around the general statistics provided below and what they may mean for you individually. The original source for these statistics is provided at the bottom of this page.

How many people are diagnosed with T-cell leukemia?

In 2023, an estimated 18,740 people (12,130 males and 6,610 females) in the United States will be diagnosed with a main type of leukemia called chronic lymphocytic leukemia (CLL). T-cell leukemia is a rare subtype of CLL, and the number of people diagnosed with it each year is much lower.

What is the survival rate for T-cell leukemia?

Due to the rarity of T-cell leukemia, specific survival rates are not available. It is estimated that 4,490 deaths (2,830 males and 1,660 females) from CLL will occur in the United States in 2023.

Doctors cannot say for sure how long anyone will live with T-cell leukemia. It is important to talk with your doctor about your diagnosis and prognosis, and if you have any questions about this information.
