Stomach cancer often has few symptoms until advanced (as was my case.). In my situation low red cell anemia displayed was like circulatory weakness or drowsiness. Being told this was often a sign of internal bleeding I had an upper and lower GI and the upper GI found a 2’ x 1.25” fully adhered tumor that had probably been there ten years and was now friable and bleeding.
Unlike Asia where upper GI and lower GI are done together, here it is often undiagnosed.
So very sorry you’re going thru this. Hope your treatment is spectacularly effective. Husband passed his 10 year date with flying colors and I’m very impressed with the medical achievements in this area. Best wishes from both of us.
The lower cell anemia was how my colon cancer was diagnosed.
