The topic Carcinoma of the Anus you are seeking is a synonym, or alternative name, or is closely related to the medical condition Anal Cancer.

Quick Summary:

  • The anus is a part of the body that is connected to the rectum of the large intestine and is the passageway, through which stool leaves the body.
  • Anal Cancer is a form of cancer that affects the anus, or anal canal. It arises after genetic mutations transform healthy cells into abnormal cells with uncontrollable growth rates.
  • Abnormal cancer cells can form new cancer cells, which can subsequently invade other tissues in the body. In addition, these abnormal cells do not ‘die-off’ as healthy cells do, resulting in the formation of a mass, or a tumor.
  • Many different types of cells are located in the anal canal, which means various types of tumors can form in the anus. However, some tumors are benign, or non-cancerous, while others are malignant, meaning they are cancerous.
  • The 2 most common type of Anal Cancer, include adenocarcinoma of anal canal and squamous cell carcinoma of anal canal. Squamous cell carcinoma type of Anal Cancer is known to be associated with human papillomavirus infection (HPV), which is a sexually transmitted disease.
  • The symptoms of Anal Cancer include rectal bleeding, constipation, and the presence of lumps in the anal canal. It is typically diagnosed through a rectal examination.
  • Cancer of the Anus is treated using radiation therapy, chemotherapy, and/or surgery. Earlier the detection, better are the treatment outcomes.
