If you suddenly find bright red or dark red blood in your stool one day, you should first consider seeing a doctor as soon as possible and not arbitrarily diagnose yourself with “hemorrhoid blood in stool” without a clear diagnosis from your doctor. You should not blindly buy medicine to treat it, and you should not see a doctor nor treat it, both of these attitudes are wrong and can cause a minor illness to become a major one, and a major one to become incurable. The most likely cause of blood in the stool is hemorrhoids, but there are also rectal cancer, rectal villous adenoma, rectal polyps, anal fissures, ulcerative colitis and other anorectal diseases can also be blood in the stool, so it is not scientific to buy hemorrhoid medicine for treatment without a doctor’s diagnosis. If the blood in the stool is caused by rectal cancer or other tumors, but you treat yourself as hemorrhoids, the consequences are serious. Rectal cancer can be cured if it is detected early and treated in time, but if it is delayed, it may develop into late stage cancer and lose the time for treatment, turning it into an incurable disease. There are so many lessons about misdiagnosing rectal cancer as hemorrhoids, and there are few cases of so-called “hemorrhoids” that are finally diagnosed as rectal cancer in hospital outpatient clinics every year. Even if it is a rectal polyp, if it is not found in time to be removed surgically, it can easily become malignant. The actual fact is that you can find a lot of people who are not able to get a lot of money from the internet.
