Lymphoma is cancer that begins in the infection-fighting cells of the immune system, called lymphocytes. These cells are in the lymph nodes, spleen, thymus, bone marrow, and other parts of the body. When you have lymphoma, the lymphocytes change and grow out of control.

There are two main types of lymphoma:

Non-Hodgkin: Most people with lymphoma have this type.

Hodgkin: Non-Hodgkin lymphoma and Hodgkin lymphoma each affect a different type of lymphocyte. Each type of lymphoma grows at a different rate and responds differently to treatment.

Although lymphoma is cancer, it is very treatable. M uchos cases may even be cured. Your doctor can help you locate the appropriate treatment for your type of disease.

Lymphoma is different from leukemia. Each of these cancers begins in a different type of cell. Lymphoma begins in lymphocytes that fight infection. Leukemia begins in the blood- forming cells within the bone marrow.

Lymphoma is not the same as lymphedema, which is a collection of fluid that forms under the skin when the lymph nodes are damaged.

Scientists don't know what causes lymphoma in most cases, but you are more likely to get it if:

• You are 60 years or older.
• He is a man.
• Having a weak immune system from HIV / AIDS, an organ transplant, or being born with an immune disease.
• Having an immune system disease, such as rheumatoid arthritis, Sjögren's syndrome, lupus, or celiac disease.
• They have been infected with a virus such as Epstein-Barr, hepatitis C, human T-cell leukemia / lymphoma (HTLV-1), or human herpesvirus 8 (HHV8).
• Having a close relative who had lymphoma.
• You were exposed to benzene or chemicals that kill insects and weeds.
• You have been treated for Hodgkin or non-Hodgkin lymphoma in the past.
• Overweight.

The common symptoms of this disease are:

• Swollen glands (lymph nodes), often in the neck, armpit, or groin.
• Cough.
• Difficulty breathing.
• Fever.
• Night Sweats.
