What are the symptoms of lymphoma and how is it diagnosed?

Lymphoma is a cancer that develops from white blood cells called lymphocytes. They are part of the immune system and are found mostly in the lymphoid organs such as the lymph nodes, spleen, bone marrow and tonsils.

There are more than 60 types of lymphoma, which can be categorised as either B- or T-cell lymphoma. They can be further classified as fast-growing (aggressive) or slow-growing (indolent) lymphoma.

In Singapore, lymphoma is the fifth most common cancer in males and sixth most common cancer in females.
