<unk>  is a rare form of cancerous lymphoma affecting T-cells. Lymphoma arises mainly from the uncontrolled proliferation of T-cells and can become cancerous.<unk>  is categorized under Non-Hodgkin Lymphoma (NHL) and represents less than 15% of all Non-Hodgkin's diseases in the category.<unk> s are often categorised based on their growth patterns as either; aggressive (fast-growing) or indolent (slow-growing). Although the cause of<unk>  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). The prognosis and treatment of<unk>  can vary drastically based on the specific type of lymphoma and its growth patterns. Due to their rarity and high variability between the different subtypes, the prognosis of<unk>  is significantly worse than other Non-Hodgkin lymphoma. The treatment of<unk>  is often similar to other Non-Hodgkin lymphomas with early-stage treatments consisting of chemotherapy and/or radiology. The effectiveness of these treatments is often varied between subtypes with most receiving a poor outcome with high relapse rates.
