Dear Doctors, This is regarding my brother, he is 25 years old, ur mother was diagnozed with colon cancer a month ago and she passed away, she was 59 when she passed, My brothe has been suffering of constipation, stomach cramps and bloud in the stools latley. His stomach is alos bloated. Our GP has asked us to undergo a colonoscopy stating that he might have a polyp in the bowels that is causing all this issues. My question is since we have the disease in the family , is there are a possibility that my brother would be effected with the same disease. Imreally worries, we have the colonoscopy set for 31st Monday.
