First of all the answer is no, hemorrhoids are not cancerous. The soft venous mass formed by the dilatation and flexion of the venous plexus under the mucous membrane at the end of the rectum and the skin of the anal canal is called hemorrhoid, also known as hemorrhoid, hemorrhoid, hemorrhoid disease, hemorrhoid disease, and so on. The medical term hemorrhoids includes internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids, and is a chronic disease in which one or more soft venous masses form as a result of varicose veins at the base of the anorectum and the anal mucosa. However, it is also common to see some patients with hemorrhoids combined with anorectal cancer in clinical practice, and often patients delay treatment by treating bleeding rectal tumors as bleeding hemorrhoids. Some studies have shown that patients with a history of anal fistula, anal fissure, perianal abscess and hemorrhoids may lead to the development of anorectal cancer, which is generally considered to be probably related to the chronic inflammatory secretions from these diseases that irritate the anorectum for a long time. Therefore, although hemorrhoids are not cancerous, early treatment is advisable.
