<s>[INST] I'm a 16 year old female and I've been having a lot of bleeding from my anus when I have a BM. I don't think I have haemorrhoids and I have a family history of bowel cancer so I'm really scared I have that, I'm too embarrassed to ask my parents of GP so please help! [/INST] Hi,From history it seems that you might be having internal hemorrhoids givingrise this problem.Consult surgeon and get examined.do not jump directly on cancer.Avoid constipation.Ok and take care. </s>
