Thanks for your question.
Travelo to Mexico raises the concern for bacterial or parasitic infection of the intestine.
Since you have history of lymphoma you are at increased risk of intestinal parasitic infection due to the compromised immunity.
Your stool should be tested for the ova and the parasites, giardia antigen, and also c difficile toxins.
You should see your doctor or a gastroenterologist for c;linical evaluation.
Antibiotic course will be required with cipro and metronidazole.
This does not seem to be cancer related at this stage.
But colonoscopy may be required if stool studies come out normal to consider that possibility.
