What is Lymphoma:
Lymphoma is a broad term encompassing a veriety of cancers of the lymph systems
Non-Hodgkin's lymphomas (NHLs) are a heterogeneous group of lymphoproliferative malignancies with differing patterns of behavior and responses to treatment. NHL usually originates in lymphoid tissues and can spread to other organs.
In Lymphoma,some of the cells in the lymph systems multiply uncontrollably and manifest into solid tumors arising in the peripheral lymphoreticular tissues particularly of the lymph nodes but also of the oro-pharynx,the gut,skin,ant other sites.

Lymphomas are divided into Hodgkin's and non-Hodgkin's lymphomas. The two are distinguished by cell type. They share similar symptoms such as painless swelling of the lymph nodes, fever and fatigue. Non-Hodgkin's lymphomas are more common with at least 15 different types. Hodgkin's generally occurs in individuals between 15-40 years of age, while non-Hodgkin's generally occurs in individuals between 30-70 years of age.
