Lymphoma is a type of cancer that affects our lymphatic system. There
are main groups of lymphoma: Hodgkin's lymphoma and non-Hodgkin's
lymphoma. These two groups encompass about 30 different types of
lymphoma.
Lymphoma develops in the lymphatic system, part of the immune system that helps filter out bacteria and fight disease. Most of us are familiar with the term lymph nodes, and they can become swollen in normal situations at any time in our lives — usually when we are sick or have an infection. When the cells in the lymph nodes begin to multiply rapidly, become malignant, and the developing condition is lymphoma.
