The anal canal

Anal cancer signs and symptoms include:

  • Bleeding from the anus or rectum
  • Pain in the area of the anus
  • A mass or growth in the anal canal
  • Anal itching

Some people with anal cancer don't experience any signs or symptoms.

When to see a doctor
The signs and symptoms of anal cancer aren't specific to this disease. Some people mistake their signs and symptoms for more common conditions, such as hemorrhoids, and don't see their doctors. Talk to your doctor about any signs and symptoms that bother you, especially if you have any factors that increase your risk of anal cancer. Treatment for anal cancer is more likely to succeed if cancer is found at an earlier stage.
