Cancers of the anus are predominantly squamous cell carcinomas. In 2017, approximately 2,100 people, including 1,395 women, were newly diagnosed. Contrary to the decreasing rates of colorectal cancer, both the incidence rate and the mortality rate from anal carcinoma have risen substantially over the past 15 years. Other countries have also reported an increase in incidence. The relative 5-year survival rates with cancer of the anus for women and men are 65 percent and 61 percent, respectively.

Human papillomaviruses are the most important risk factor

In Germany, about 90 percent of anal carcinomas can be traced back to an infection with human papillomaviruses (HPV). Other risk factors are smoking, certain sexual practices (frequently changing sexual partners, passive anal sex) and chronic immunosuppression. The risk of developing anal carcinoma is much higher among HIV-positive persons, especially among HIV-positive men who have sex with men, than in the general population. The Standing Committee on Vaccination (STIKO) recommends that girls and boys be vaccinated against HPV, preferably between the ages of 9 and 14 years.
