Hi @dbamos1945, From my understanding, gastric malt Non-Hodgkin’s lymphoma (marginal zone lymphoma of Mucosa-Associated Lymphoid Tissue~MALT) is generally slow to develop and the stomach is the most common site for the site of MALT lymphoma. Is this where your lymphoma was found?

There are several articles on line which talk about MALT so I’m posting two from credible sources that I think will be helpful for you:
This from MDAnderson.org:

From Cleveland Clinic.

With a new diagnosis I know you have a lot of questions and concerns. Until you know what type of treatment plan your doctor has it’s difficult to speculate on what the side effects might be or followup care. Has your doctor discussed treatment options?
