T-Cell Prolymphocytic Leukemia (T-PLL)

T-Cell Prolymphocytic Leukemia (T-PLL) is a rare and aggressive type of blood cancer that affects a specific type of white blood cell called T-lymphocytes. In this article, we will simplify the complex medical jargon and provide clear, concise information about T-PLL, including its types, causes, symptoms, diagnostic tests, treatments, and drugs.

Types of T-Cell Prolymphocytic Leukemia:

T-PLL typically has one main type, but there are variations based on the genetic changes within the cancer cells. These variations are important for treatment decisions, but they all involve abnormal T-lymphocytes growing uncontrollably in the blood and bone marrow.
