I'm 48 yo male. I'm really convinced I have GI cancer and so much of the symptoms point to PC. I been bloated with upper ab pain and left flank pain for a month. Then the back pain started. Now I have little appetite and am starting to lose weight. I got a ultrasound which found nothing. Now awaiting CT abdomen results. Its been several days. Havent heard anything. I know googling doesn't help. But its hard not to do something. Struggling..
