CausesCancer occurs when cells in the body divide without control or order. Eventually, these uncontrolled cells form a growth or tumor. The term cancer refers to malignant growths. These growths can invade nearby tissues and spread to other parts of the body. There is evidence that human papillomavirus (HPV) infection is linked to many anal cancers. However, most people who have been infected with HPV do not get anal cancer.
Risk FactorsFactors that increase your risk of anal cancer include:
- HPV infection
- Receptive anal intercourse
- Multiple sexual partners
- HIV infection
- Use of immunosuppressant drugs
- Cervical dysplasia or cervical cancer
SymptomsSome anal cancers do not have symptoms. When symptoms do occur, they may include:
- Anal bleeding with and without a bowel movement
- Pain or pressure around the anus
- Itching or discharge from the anus
- A lump near the anus
- Change in bowel habits
- Thinning in the width of the stool
DiagnosisYou will be asked about your symptoms and medical history. A physical exam will be done. A digital rectal exam may also be done.The rectum and anus may need to be examined. This can be done with:
- Blood tests

A meta-analysis found that mothers participating in a prenatal exercise group were less likely to have a large newborn, less likely to need a cesarean section, and no more likely to have a low birthweight baby than those who did not exercise. The study supports proper prenatal care advice which advocates for mothers to exercise during pregnancy if allowed by the physician.
