How often should I have an endoscopy test? My grandfather had stomach cancer, grandmother died from oesophageal cancer and mother suffers from ulcers.

Endoscopy. There is no standard guideline for how often you should have an endoscopy in this situation. In the absence of barrett's esophagus, h pylori, or symptoms there is generally no clear indication for recurrent endoscopy.
H. pylori. Infection is possibility, so have it checked. It is rare to get GI cancers before age 40, but your family history is quite impressive. There are cancers that have genetic predispositions. Your doctor should be able to sort it out. If you have GI symptoms now, you should have endoscopy immediately.

Had an endoscopy today and heme were seen. Also severe gastritis and ulcers. 4 family members died of stomach cancer. Should I be concerned of heme?

Priorities. Heme is another way of saying "blood". This is commonly seen with ulcers and gastritis. I would be most concerned with your family history of gastric cancer, however. Any ulcers in your stomach should be biopsied, and you should be checked for a bacterial infection called h pylori. These can both be associated with gastric cancer. Ask your gastroenterologist.

Yes, somewhat. This indicates that there has been bleeding in your GI tract, most likely in your stomach. You should get any ulcer biopsied, and, at least, stop the bleeding. You should get a full work-up of any ulcers, tested for h. Pylori infection, and very aggressive follow-up due to your family history, along with therapy for your gastritis. You should start your follow-up and see your doctor very soon. Read more...
