Lymphoma is a cancer of the lymphatic system, a system that’s primary function is in supporting the body’s immune functions. In lymphoma, cancer develops in one or more groups of lymph nodes.

Lymphoma is defined in two groups:

  1. Hodgkin lymphoma: During diagnosis, the particular cell called the Reed-Sternberg cell (a type of white blood cell) is found amongst the cells from the lymph node.
  2. Non-Hodgkin lymphoma: In NHL, blood cells called lymphocytes become abnormal, dividing continuously outside of the bodies control. Over time, the number of lymphoma cells increases and they form a lump called a tumour.
