Lymphoma
Lymphoma is a group of blood malignancies that develop from lymphocytes. Signs and symptoms may include enlarged lymph nodes, fever, drenching sweats, unintended weight loss, itching, and constantly feeling tired. About 90% of lymphomas are non-Hodgkin lymphomas. Risk factors for Hodgkin lymphoma include infection with Epstein–Barr virus and a history of the disease in the family.
