Hemorrhoids do not turn into cancer, and you can be absolutely sure about this. Hemorrhoids are a benign disease that is essentially a varicose of the hemorrhoid veins and the veins surrounding them, which means that the veins at the end of the rectum do not have good blood flow, causing them to swell up and take on the appearance of a small meatball-like change. It is not precancerous and will not turn into rectal cancer. However, hemorrhoids themselves can have many various hazards, such as blood in the stool, prolapsed internal hemorrhoids, perianal discomfort, perianal itching, etc. However, there is no contradiction between having hemorrhoids and getting rectal cancer or colon cancer. Although hemorrhoids will not turn into rectal cancer, some of its symptoms can sometimes be confused with rectal cancer, both of which manifest as blood in the stool. The actual hemorrhoids are also a good idea to have regular annual medical checkups, especially after the age of 40, to check for the possibility of hemorrhoids combined with bowel cancer.
