Lymphoma causes

Lymphoma is a malignant tumor of the lymphatic system. The causes of lymphoma are complex, including exposure to toxins, chemotherapy and radiation. In addition, pathogen infection and immune dysfunction can also cause lymphoma. Clinically, patients receiving chemotherapy or radiation therapy can produce lymphoma, because chemotherapy and radiation can cause malignant transformation of lymphocytes. Other diseases, including ulcerative colitis, Crohn's disease and tuberculosis, can also trigger lymphoma.
