Natural History Of HPV Infections In The Anus In Men And Women Anal Cancer And HPV
Anal cancers are more common in women than men in the general population.
Since anal cancer is higher among MSM (men who have sex with men) and men and women who are immunocompromised to transplantation for HIV.
Anal cancers occur relatively infrequent when compared to cervical cancer.
Anal intercourse is without question a factor in the acquisition of HPV infection, but other modes of transmission (see autoinoculation above) are also contributory.
The incidence of anal cancer is about 2% per year among both men and women in the general population since the 1970’s.
Risk factors for anal cancer include exposure to HPV, chronic irritation caused by fissures or fistulas, smoking, and immunosuppression are both similar in both men and women.
Changes in sexual behavior in the last several decades no doubt contribute to an increased risk of exposure to HPV in the anal canal.
