  • Lymphoma is a group of blood cell tumors that develop from lymphocytes. It is sometimes used to refer to just the cancerous ones rather than all tumors. Symptoms may include: enlarged lymph nodes that are not generally painful, fevers, sweats, itchiness, weight loss and feeling tired among others. The sweats are most common at night. There are two main types: Hodgkin lymphoma and non-Hodgkin lymphoma, with two others, multiple myeloma and immunoproliferative diseases, also included by the World Health Organization within the category. Non-Hodgkin lymphoma makes up about 90% of cases and includes a large number of sub-types. Lymphomas are part of the broader group of neoplasms called tumors of the hematopoietic and lymphoid tissues. Risk factors for HL include: infection with Epstein–Barr virus and having other in the family with the disease. Risk factors for NHL include: autoimmune diseases, HIV/AIDS, infection with human T-lymphotropic virus, eating a large amount of meat and fat, as well as immunosuppressant medications and some pesticides. They are usually diagnosed by blood, urine, or bone marrow testing. A biopsy of a lymph node may also be useful.
