are hemorrhoids dangerous,Will hemorrhoids become cancerous?

    Hemorrhoids, one of the most common diseases in the anus, are divided into "internal hemorrhoids" and "external hemorrhoids".

    The causes of internal hemorrhoids, except for a very small number of anal vascular malformations, most patients are due to constipation, dry stools, feces staying in the end of the rectum for too long, or poor bowel habits, squatting and sitting in the toilet for too long. Affect the venous blood return in the anus. Rectal cancer is a malignant lesion that occurs on the rectal mucosa. The early symptoms of rectal cancer are blood in the stool or mixed blood in the stool, with mucus, and no pain.

    Internal hemorrhoids and rectal cancer are two different diseases, their causes are completely different: internal hemorrhoids occur in the hemorrhoidal veins under the mucosa of the anus or rectum, and rectal cancer occurs on the mucous membrane of the rectum. Even though some anal canal cancer and internal hemorrhoids occur in the same location, anal canal cancer comes from the anal canal epithelium and is not caused by hemorrhoids. Some patients with rectal cancer may have been diagnosed as internal hemorrhoids by doctors, and later diagnosed as cancer by doctors. This is not the transformation of internal hemorrhoids into cancer, but the misdiagnosis of the first doctor. In fact, it is very easy to distinguish internal hemorrhoids from rectal cancer. The doctor can diagnose it by examining the rectum through the anus with his fingers. This kind of misdiagnosis is often caused by the first doctor only listening to the patient's complaint and not doing the finger rectal examination. Internal hemorrhoids will not become cancer.
