Lymphoma is a cancer that begins in cells called lymphocytes that fight infections of the immune system. These cells are found in the lymph nodes, spleen, thymus, bone marrow, and other parts of the body. Lymphoma causes lymphocytes to change and become out of control. There are two main types of lymphoma – non-Hodgkin: Most people with lymphoma have this type; and Hodgkin : various types of lymphocytes are involved in non-Hodgkin’s lymphoma and Hodgkin’s lymphoma. Different types of lymphoma have different growth rates and different responses to treatment.
Lymphoma is highly treatable and the outlook depends on the type of lymphoma and its stage. Your doctor can help you find the right treatment for your type and stage of illness. Lymphoma is different from leukemia. Each of these cancers begins with a different cell type.
Lymphoma begins with lymphocytes that fight the infection. Leukemia begins with hematopoietic cells in the bone marrow.
1. Swelling of Lymph Nodes
Lymph node swelling usually occurs as a result of a bacterial or viral infection. In rare cases, swelling of the lymph nodes may be caused by cancer. Lymph nodes, also known as lymph glands, play an important role in the body’s ability to fight infections. They act as filters and trap viruses, bacteria, and other pathogens before they infect other parts of the body. Common areas where swollen lymph nodes may be noticed are the neck, chin, armpits, and groin.
In some cases, time and warm compresses are sufficient to treat swelling of the lymph nodes. If the infection causes swelling of the lymph nodes, treatment depends on the cause. Some swollen lymph nodes return to normal, and mild infections improve. However, if you are worried, or if swelling of the lymph nodes appears for no apparent reason, or they appear to be growing, or they have been there for 2-4 weeks– make sure to see a doctor.
