What is Lymphoma?

Lymphoma is a cancer of white blood cells called B-lymphocytes, or B-cells. These cells multiply rapidly and form tumors. Lymphoma is closely related to lymphoid leukemias, which also originate from lymphocytes but typically involve only circulating blood and the bone marrow (where blood cells are produced in a process called haematopoesis) and usually do not form tumors statis.Pasien with weakened immune systems, such as from HIV infection or from certain drugs or medications, have a higher risk of developing lymphoma. 

Lymphoma tumor can occur in bone, stomach, liver, brain or other body parts. The first sign of lymphoma is swollen lymph nodes, fever, night sweats, and weight loss of more than 10 percent. This symptom occurs with some other illnesses associated with AIDS. 

lymphoma is caused by long-term stimulation of the immune system. When B-cells to multiply more rapidly over the years, more and more mutations occur in these cells. Some of these mutations can lead to cancer. Approximately 4 percent of people with symptoms of HIV disease had lymphoma each year.
