Lymphoma is a cancer of the lymphatic system, which encompasses the thymus gland, tonsils, spleen, bone marrow, appendix and lymph nodes. The two most common types of lymphoma are Hodgkin's lymphoma and non-Hodgkin's lymphoma. Cells in the lymphatic system grow abnormally and may spread throughout the body. As the disease progresses, the body's ability to fight infection becomes severely compromised.

Common causes
The cause of lymphoma is currently unknown. The condition involves the mutation of immune system cells, which then multiply and kill healthy cells.  

According to the Mayo Clinic, there are various forms of Hodgkin's lymphoma, each of which involve different types of immune system cells.

Common symptoms:
• Swelling in the lymph nodes in the neck, underarm or groin, which is often painless
• Chronic fatigue
• Recurring fever
• Night sweats
• Unexplained weight loss
• Itchy skin
• Loss of appetite 

Treatment options: 

Course of treatment will depend on the type and stage of the disease. Typical treatments include chemotherapy, radiation therapy and stem cell treatments.
