Lymphoma is a form of cancer that affects the immune system - specifically, it is a cancer of immune cells called lymphocytes, a type of white blood cell. There are two broad types of lymphoma and many subtypes.The two types of lymphoma are described as: Hodgkin's or non-Hodgkin's
The symptoms typically involve painless swelling of the lymph nodes (glands), often in the neck or armpits where these nodes are concentrated. Swelling may also occur in the groin and abdomen, in any part of the body.You may be familiar with this sign because the lymph nodes in the neck (commonly referred to as "glands") can become swollen during infections such as the cold - but here the swelling subsides, whereas it does not in cancer
patients diagnosed with a high-grade or intermediate lymphoma will typically require immediate and intensive treatment to help slow down tumor growth and, eventually, to shrink the tumor Where indolent lymphoma turns into aggressive lymphoma this can be especially difficult as the tumors may be widespread, whereas an aggressive lymphoma may be caught earlier and still be somewhat localized.
