I had a relative who never went in for physicals, unlike your husband, and when he got blood and indigestion symptoms he finally relented and went in, his colon cancer was at
Stage 3, he underwent surgery, chemo and radiation, years of followup, and even tho his
Stage 3 was serious, he's a 15-year survivor with no further problems, other than occasional constipation because they removed some of his colon. I hope all this info helps you cope.
