The network of lymph nodes in your body works hard to filter bacteria and fight off disease. The cells in your lymph nodes naturally grow, divide and continually replace themselves to do this.
However, when these cells divide too rapidly and grow without any order or control, too much tissue is formed and tumors begin to grow. These lymphomas–-the cancerous growth of these cells--can then spread to other organs
There are two types of lymphoma:
In Hodgkin’s lymphoma, one particular abnormal and malignant cell – the Reed-Sternberg cell, named for the scientists who discovered it – is found within the lymph nodes. This cancer has a predictable pattern as it spreads through body.
Non-Hodgkin’s lymphoma has two cell types that may become cancerous: B-cells and T-cells.
Facts about Lymphoma
- According to the Leukemia & Lymphoma Society, more than 63,000 people are diagnosed with lymphoma each year
- The annual incidence of lymphoma has almost doubled over the last 35 years
- The primary cause of lymphoma is not certain, but studies suggest that certain factors, such as exposure to carcinogens, pesticides, herbicides, viruses and bacteria, may play a role
- Persons with HIV infection are more at risk of developing lymphoma
