====== T-cell and NK/ T-cell lymphoma ======


A [[T-cell]] lymphoma is a rare form of cancerous [[lymphoma]] affecting T-cells.

Lymphoma arises mainly from the uncontrolled proliferation of T-cells and can become cancerous. 


T-cell lymphoma is categorized under [[Non-Hodgkin Lymphoma]] (NHL) and represents less than 15% of all Non-Hodgkin's diseases in the category. 

T-cell lymphomas are often categorized based on their growth patterns as either; aggressive (fast-growing) or indolent (slow-growing).

Although the cause of T-cell lymphoma is not definitive, it has been associated with various risk factors and viruses such as Epstein Barr virus (EBV) and Human T-cell leukemia virus-1 (HTLV1).
