Lymphoma is the most common blood cancer. It develops in the lymphatic system including lymph nodes, spleen, and bone marrow. The lymphocytes, a type of white blood cell, grow abnormally causing the lymphoma. The exact causes are unknown. There are two main types of lymphoma.
Hodgkin Lymphoma is not as common but usually is diagnosed in young adults or older adults over the age of 50.
Non-Hodgkin Lymphoma is the most common and is broadly divided into two groups: B-cell lymphoma and T-cell lymphoma. There are at least 61 types of non-Hodgkin lymphoma.
- Lymph nodes that are swollen, but not painful, in the neck, armpit or groin areas.
- Weight loss that is unexplained, or unintentional
- Night sweats
- Chest pain, coughing or trouble breathing
- Weakness, or tiredness, that does not improve with time
- A feeling of fullness, swelling, or pain in the abdomen
If you have any of these persistent symptoms or signs that are of particular concern, please consult your physician.
