<s>[INST] Hi doctor, I am a 47 year old female. My weight is 95 kg. My symptoms are blood in stools and stomach bloating. Initially, we suspected piles. But, the doctor said it may be colon or rectal cancer. Colonoscopy, blood tests and CT scan are done and I have attached the reports for your reference. I would like to know the actual problem. How serious is it? [/INST] Hi. For further information consult a surgical gastroenterologist online --> </s>
