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 categorised 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).
