Living with Gastric non-hodgkin lymphoma

A lymphoma, a cancer of immune system cells, that starts in the stomach.

Understanding Gastric non-hodgkin lymphoma

Gastric non-Hodgkin lymphoma is a non-Hodgkin lymphoma that arises in the stomach.

It is an extranodal lymphoma, meaning it starts outside the lymph nodes, with most of the mass in the stomach. GARD says the vast majority of cases are diffuse large B-cell lymphomas and B-cell lymphomas of the mucosa-associated lymphoid tissue.
