Anal cancer

Anal Cancer

Anal cancer (pronounced /ˈeɪnəl ˈkænsər/) is a type of cancer that forms in tissues of the anus. The anus is the opening of the rectum (last part of the large intestine) to the outside of the body.

Etymology

The term "anal" is derived from the Latin word "anus" which means "ring, circle". The term "cancer" is derived from the Latin word "cancer" which means "crab or creeping ulcer".

Symptoms

Symptoms of anal cancer can include bleeding from the anus or rectum, pain or pressure in the area around the anus, a lump near the anus, a change in bowel habits, or anal itching or discharge.

Causes

Anal cancer is often linked to the Human Papillomavirus (HPV). Other risk factors include being over age 50, having many sexual partners, having receptive anal intercourse, smoking, or having a weakened immune system.

Diagnosis

Diagnosis of anal cancer is made through physical examination, biopsy, and imaging tests such as CT scan or MRI.

Treatment

Treatment options for anal cancer include surgery, radiation therapy, and chemotherapy. The choice of treatment depends on the stage of the cancer, the patient's overall health, and personal preferences.
