T-cell acute lymphoblastic leukemia (ALL) is a less common subtype of acute lymphoblastic leukemia. It happens more often in adults than in children.

T-cell ALL starts in immature cells that would normally develop into T cells, a type of white blood cell. T cells are part of your immune system and help your body fight disease.

In T-cell ALL, these immature cells do not develop into normal, working blood cells. Instead, they multiply out of control.

How T-cell ALL is Treated

Treatment for T-cell ALL is different for each person. Most people with ALL start with chemotherapy.

Depending on your disease and how it responds to treatment, your care team may recommend other treatments, such as a blood and marrow transplant or treatment through a clinical trial.

Your care team will explain your options and recommend a treatment plan based on your disease and your needs.
