Swollen anus: Causes, symptoms, diagnosis, and treatments
A bit like a spot on your face, anything on your backside feels about ten times the size too. The anus or bottom is the last portion of the alimentary canal where waste material exits the body controlled by a strong sphincter muscle. Between the anus and the vagina in women and the scrotum in men, sits the perineum. Adjacent to the anus, it lies underneath the pelvis supporting the pelvic floor. It is shaped like a diamond. Bacteria and germs thrive here.
The anus is an opening in the lower part of the digestive tract. When stool fills the rectum, the sphincter muscle relaxes, letting stool pass through the anus and out of the body. The external anal sphincter closes off the anus when stool has passed. Lumps that form around the anus — for a variety of reasons — can cause it to feel hard. There may also be swelling, pain , and discharge.
Anal cancer is a type of cancer that forms in tissues of the anus. The anus is the opening of the rectum to the outside of the body and at the end of the GI tract. Sometimes anal cancer causes no symptoms at all.
