I had a friend with a bulging stomach. It was drained by a doctor as it contained a lot of liquid. Cancer was also Dx, stage 4 at this time in his colon. Later exploratory surgery indicated cancer in the appendix which is very hard to Dx w/o surgery. I would get a doctor for a 2nd opinion. Hopefully your condition is not this, but cancer sometimes has no direct symptoms. You may want to consider getting one of the cancer tests available for home use. It can be other things besides cancer, of course. I would also check diet/supplements for folic acid (a man made substitute for vitamin B9). You are in my prayers, Sister Marie
