Lymphoma is a cancer that starts in infection fighting cells belonging to the immune system. These cancerous cells are present in a lot of body parts like the lymph nodes, thymus, spleen and bone marrow. Lymphocytes modify themselves and grow rapidly when there is a lymphoma.
Hodgkin and non-Hodgkin lymphomas both affect different types of lymphocytes. Each type grows at different speeds and has different responses to treatment. Despite being cancers, lymphomas are quite treatable. In many instances they get completely cured as well. Lymphomas differ from leukemia as both start in different kinds of cells. Lymphomas start in lymphocytes while leukemia start in bone marrow cells.
In most cases scientists aren’t aware of the cause of lymphoma. You are more disposed to having it if:
A doctor can check for enlarged lymph nodes and will look for lymphoma symptoms. This doesn’t usually imply that there are cancer cells. A biopsy may be needed to detect cancer cells. To do this, a part or the entire lymph node may be removed. Another way to do this is to take small amounts of tissue from the node affected. The treatment depends on the kind lymphoma and the extent of its spread.
The main Hodgkin lymphoma treatments are radiation therapy and chemotherapy. Stem-cell transplant may be needed if the above treatments don’t have any effect. The cancer cells get killed by this treatment, but stem cells present in the bone marrow also get destroyed.
