There must be risks in doing this kind of inspection. The doctor will tell the truth, the focus of gastrointestinal endoscopy is different, and there are many reasons for gastrointestinal bleeding. The main purpose of gastrointestinal endoscopy is to find the location and cause of bleeding, and the other one can also find tumors. I suggest a gastroscope first. If you have bleeding tendency, you can treat it first, and then check the routine stool and occult blood. If it is normal, you can temporarily not do colonoscopy. If you are still positive for occult blood, you need to do colonoscopy again, because occult blood is often positive for no obvious reason, and most of them will consider whether there is a colon tumor.
