Because HPV infection doesn’t usually show any signs, you probably won’t know you have it. Most people can therefore get HPV and pass it on without even knowing it.4
In most people, HPV is harmless and has no symptoms, but in some people the virus may persist and lead to disease of the genital area, including genital warts and cancers of the anus.1,2,4,5

GENITAL WARTS
Genital warts are benign, flesh-coloured growths that are most often caused by certain “low-risk” types of HPV (types 6 and 11).1,5–7
Genital warts most often appear on the external genitals or near the anus of males and females.6 Genital warts may cause symptoms such as burning, itching and pain.7 The types of HPV that cause genital warts are different from the “high-risk” types that can cause cancer.1 After sexual contact with an infected person, genital warts may appear within weeks, months, or not at all.7
A doctor can usually recognise genital warts just by seeing them.2
Genital warts can disappear on their own without treatment; however, there’s no way of knowing if they will disappear or grow larger. Depending on size and location of the warts, there are several treatment options. A special cream or solution may be applied to the warts. Some genital warts can be removed by either freezing, burning, or using laser treatment. However, no matter the treatment, there’s a chance that genital warts will reappear after treatment, since the types of HPV that cause them may still be present.6
ANAL CANCER
Anal cancer is an uncommon cancer that affects both males and females. Infection with certain types of “high-risk” HPV is a risk factor for anal cancers as well as other risk factors, including cigarette smoking and immunodeficiency syndromes.8
Anal cancer sometimes has no symptoms at first. Common symptoms can include bleeding and discomfort in the area. Other symptoms can include pain,itching, straining during a bowel movement, change in bowel habits, change in the diameter of the stool, discharge from the anus and swollen lymph nodes in the anal or groin area. A doctor may diagnose anal cancer using a number of tests such as a physical exam and history, digital rectal examination (DRE), anoscopy, proctoscopy, biopsy or ultrasound.8
For patients diagnosed with anal cancers, the main treatment options are surgery, radiation therapy and chemotherapy.8
MEN WHO HAVE SEX WITH MEN
Men who have sex with men may be at increased risk of HPV infection, genital warts and anal cancer.1
Men who have sex with men seem to be less likely to develop immunity after an infection with HPV type 16 - the HPV type most often linked to anal cancer.1,9 In fact, men who have sex with men may be up to 20 times more likely to develop anal cancer,10 and 2-3 times more likely to develop genital warts than heterosexual males.11
Prevention of HPV infection is an important consideration as there is currently no routine screening program for early detection of anal cancer.12
