What is an anal layer?
Anal layer, also called the anal edge, is the surface of the ring opening of the rectum through which the fecal matter is eliminated. Anus consists of two parts: anal channel and anal edge. Both sections are located in anal sphincter, which is the muscles that control the expulsion of the feces. The anal edge indicates a transition point from the inner mucosa of the anal canal to the surface of the perianal skin. Changing or dysplasia in the cells of the surface layer of the anal layer may resemble early formation of hemorrhoids. Once the examination is performed and biopsy of changed tissue is diagnosed, a condition called carcinoma in situ (CIS) or Bowen's disease may be diagnosed. These non -invasive pre -cancerous cells usually do not spread behind the continuer's surface layer, but their presence may indicate the possibility of developing invasive anal cancer in tbud. Verge cancer is sometimes called perianal skin cancer. It is usually found that cancer is spinocellular carcinoma after the evaluation of biopsied tissue in the laboratory.Unlike the cancer of the anal canal, the surface cancer of the surface often mimics skin cancer and is more difficult to treat it.
Anal Verge can also develop malignant melanoma. Melanocytes producing pigments are responsible for creating melanin that causes brownish rectum color. In general, melanoma develops on the skin that is exposed to the ultraviolet (UV) rays of the sun. The diagnosis of malignant melanoma of the anal edge is unusual, but if it is discovered in the early stages, the complete excision of the tumor may lead to complete recovery.
Other Verge Cancer, which is more common in SKV Tom is exposed to excessive sunlight is the basal cell carcinoma. Treatment of this cancer includes surgical removal of growth. It is recommended to ensure that any cancer reconstruction is diagnosed and treated quickly.
Operations to remove cancer of the anal edge is called resction of abdominoperineal (APR). Usually the rectum, anal sphincter, anal channel and the anal layer are removed, and the lower end of the intestine is connected to the opening in the abdomen called ostomia. Most patients lose the ability to have normal bowel movements. The surgeon can sometimes decide to perform an intesfinkteric resection (ISR) instead of APR. This surgery enables the excision of cancer growth without the subsequent loss of intestinal control, which many people endure to remove the anal sphincter and rectum.
