Since blood in stool is the most common symptom of hemorrhoids, it can lead some people to overlook a common cause of blood in stool – colorectal cancer, and clinically, we often see patients mistake blood in stool as hemorrhoids and delay the diagnosis and the best time for treatment. So, is blood in stool hemorrhoids? Or is it cancer? The treatment of tumor is about early detection. Active colonoscopy and anorectal examination can greatly improve the early detection rate of colorectal cancer, and people over 45 years old are encouraged to have at least one colonoscopy. Because the treatment effect of early detection can be very good and even cure the tumor. If colorectal cancer is detected early, the survival period can reach 5-20 years or even lifetime; if detected in the middle stage, the survival period is mostly 3-5 years; if colorectal cancer has developed to advanced stage, the general survival period ranges from 8 months to 1 year. It is not good to avoid examination because of the fear of tumor, and it may be late if you have to delay until the symptoms are obvious and then forced to go for examination. Therefore, when there are symptoms such as blood in stool, change in stool habit, weight loss, unexplained anemia, etc., it is important to go to a regular hospital in time, and as a general health check-up, people over 45 years old are encouraged to have at least one colonoscopy. Of course there are many causes of blood in the stool, such as: anal fissures, large intestinal polyps, ulcerative colitis, Crohn’s disease, mesenteric thrombosis, etc. Here I would like to remind you that you should not simply think that blood in the stool is a case of hemorrhoids again, many other causes and diseases may also cause blood in the stool, you should go to the hospital to find the root cause of the problem and then regular treatment is the right approach.
