Sarcoma around the anus is related to four diseases

The growth of sarcoma around the anus often causes extreme discomfort. Generally speaking, the appearance of sarcoma in the anus is mostly related to the following four diseases.

①Hemorrhoids.

Internal hemorrhoid prolapse, annular mixed hemorrhoids, external hemorrhoid thrombosis, etc. often cause lumps outside the anus when defecating forcefully.

② Rectal prolapse.

It refers to a disease in which the anal canal, rectal mucosa or rectum, and part of the sigmoid colon shift downward and protrude out of the anus, commonly known as rectal prolapse. The treatment of this disease is mainly to improve the weakness of Qi and blood, and eliminate the causes such as diarrhea, constipation, and long-term cough.

③Rectal polyps.

It is a common benign tumor of the rectum, which can be single or multiple. Most polyps are round or oval tumors with pedicles. They are prone to occur at the lower end of the rectum. They can protrude from the anus during defecation and retract after defecation. Adenomatous polyps are precancerous lesions that can turn into rectal cancer if treatment is delayed.

④Rectal leiomyosarcoma.

Rectal leiomyoma is formed by the proliferation of abnormal smooth muscle cells and is mostly located in the lower rectum. Its growth pattern is often to bulge into the rectal cavity. If not treated surgically in time, it may turn from a leiomyoma into a leiomyosarcoma, that is, from a benign tumor to a malignant one, causing the rectum to narrow and leading to constipation, anal distension, and bloody stools.
