Overview
Common Risk Factors
Common risk factors associated with anal cancer are:
- Human papillomavirus (HPV) infection, notably HPV-16.[1]
- Sexual activity: Having multiple sex partners or having anal sex, due to the increased risk of exposure to the HPV virus.[2]
- Smoking: Current smokers are several times more likely to develop anal cancer compared with nonsmokers.[2]
- Immunosuppression, which is often associated with HIV infection.[2]
