There are many different strains of the human papillomavirus (HPV), and some strains can cause genital warts or cancers such as cervical, anal, and penile cancers.
Causes
Even if an infected individual does not have visible warts or symptoms, the virus can be transmitted through vaginal, anal, or oral sex with an infected individual. Various factors can increase the risk of infection with HPV, including multiple sexual partners, unprotected sexual activity, and weakened immunity.
Symptoms
Many people with genital HPV infection do not experience any symptoms and may not be aware that they are infected. Some individuals, however, may develop visible genital warts, which are small, flesh-colored bumps or clusters on the genital or anal areas. Occasionally, HPV infection may cause abnormal changes in cells in the cervical, anus, or other genital areas, which may increase the risk of cancer.
Diagnosis
An HPV infection in the genital area is typically diagnosed through a combination of medical history, physical examination, and diagnostic tests:
-
A healthcare provider may visually inspect the genital or anal area for signs of warts or abnormal changes.
-
In women with cervixes, Pap smears (or Pap tests) may be performed to screen for abnormal cervical cells that may indicate HPV infection or cervical cancer.
-
This test detects the presence of HPV DNA in cervical cells and can help identify high-risk HPV strains that may increase cervical cancer risk.
-
Anal Pap Smear: Anal Pap smears may be recommended for individuals at increased risk of anal cancer, such as men who have sex with men (MSM) or those with genital warts or abnormal cervical Pap smears.
Treatment
HPV infection cannot be cured, but there are treatments available that can manage symptoms and reduce complications:
-
To shrink or eliminate visible genital warts, topical medications such as imiquimod or podophyllotoxin may be prescribed.
-
There are several surgical procedures that can be used to remove genital warts, including cryotherapy (freezing), electrocautery (burning), and surgical excision.
-
In individuals with abnormal cervical or anal Pap smears, further monitoring or treatment may be necessary to prevent cancer from developing.
Prevention
In order to prevent genital HPV infection, vaccination, safe sex practices, and regular screening are important:
-
The HPV vaccine is highly effective at preventing infection with the most common high-risk HPV strains that can lead to cancer. The vaccine is recommended for both males and females starting at the age of 11 or 12.
-
Consistent and correct condom use can reduce HPV transmission risk, although they may not provide complete protection.
-
The risk of infection can be reduced by limiting the number of sexual partners and choosing partners who have been vaccinated against HPV.
-
Screening: Regular Pap smears and HPV testing for cervical cancer screening can detect abnormal changes early and prevent cancer from progressing. Anal Pap smears may be recommended for individuals at increased risk of anal cancer.
Conclusion
There is no cure for HPV, but vaccination, safe sex practices, and regular screenings can reduce infection risk and reduce the risk of complications. Genital HPV is a common sexually transmitted infection that can cause warts and increase cancer risk. Cancer can be prevented if genital warts and abnormal cervical or anal cells are detected and treated early.
