Lymphoma is the general term for cancers that develop in the lymphatic system. Lymphoma originates in developing lymphocytes (B-cells and T-cells), which have undergone a malignant change. They multiply without any proper order, forming tumors, which are collections of cancer cells. These tumors cause swelling in the lymph nodes and other parts of the body. Over time, malignant lymphocytes (called lymphoma cells) crowd out normal lymphocytes and eventually the immune system becomes weakened and can no longer function properly. This lymphoma affects the lymph nodes first and could also affect other lymphoid organs like spleen and bone marrow. The Non-Hodgkin’s lymphoma can be classified into 2, depending on how fast or slow these tumors grow within the body namely; Aggressive non-Hodgkin’s lymphoma and Indolent non- Hodgkin’s lymphoma. Non-Hodgkin’s lymphoma can also be classified based on the type of cells they emanate from namely; B-cells lymphoma and T-cells lymphoma. B-cell lymphoma are lymphomas that arise from developing B-cells, while T-cell lymphoma are lymphomas that arise from T -cells [1].
