Symptoms

Many of the symptoms of anal cancer can also be caused by benign conditions like hemorrhoids, fistulas, and warts, but doctors can often detect anal cancer early because it forms in an easily accessible part of the digestive tract. Additionally, if you are at high risk for anal cancer, you can undergo routine anal Pap smears to identify and treat precancerous changes in the anus. Here are some common symptoms of anal cancer:

  • Bleeding from the rectum and anus
  • Lump near the anus
  • Abnormal discharge from the anus
  • Pain around the anus
  • Narrowing of the stool
  • Changes in bowel habits
