What is lymphoma?
A person with lymphoma has abnormal cells in the lymph nodes or spleen that multiply out of control. These cells, called lymphocytes, are part of the immune system, which fights infection. The cells can form tumors and spread to other parts of the body. The incidence of many forms of cancer are declining in the US, but lymphomas have become more common. The two main types of lymphoma are Hodgkin's disease and non-Hodgkin lymphoma. The cause of lymphoma is unknown, but genetics may play a role in determining risk.

What are the symptoms of lymphoma?
Symptoms of lymphoma may include chest pain, cough, difficulty breathing, fatigue, fever, excessive sweating, night sweats, pale skin, weight loss, and swollen lymph glands.

How does the doctor treat lymphoma?
Treatment for lymphoma may include chemotherapy, radiation therapy, and surgery to remove a tumor. In some cases, treatment for lymphoma may include removal of the spleen.
