Hello there. As long as your boyfriend has gone this long without a scope I would not panic and wait to see what the endoscopy results are.
Stomach cancer is uncommon in the United States, and the number of people diagnosed with the disease each year is declining. Stomach cancer is much more common in other areas of the world, particularly Japan.
Besides an endoscopy with biopsy, imaging tests used to look for stomach cancer include computerized tomography (CT) and a special type of X-ray sometimes called a barium swallow.
I would take this one step at a time and I hope the scope gives you some information.
