Learn how HPV can lead to HPV-associated cancers.
What is HPV?
How is HPV transmitted?
As the most common sexually transmitted disease, most men and women get HPV infection in their lifetime.
- HPV is transmitted through sexual contact (vaginal, anal, and oral)
- Most people get their HPV infection shortly after the onset of sexual activity
- HPV infection can persist for many years
- HPV infection is associated with the number of sexual partners
- HPV infection is linked to tobacco smoking
What does HPV do?
- Most HPV infection can be cleared spontaneously without any symptoms
- Low-risk HPV infection can cause genital warts
- High-risk HPVs are carcinogenic
- causing almost 100% of cervical cancer
- causing 90% of anal cancer
- causing 70% of oropharyngeal cancer
- Cervical cancer is the fourth most common cancer in women worldwide
- 85% of cervical cancer occurs in developing countries
- Incidence has reduced 74% in countries where a pap smear or HPV screening is implemented
- The target for cervical cancer screening coverage is 93% by 2020
- HPV positive oral cancer has increased by 700% in the past three decades, while HPV negative oral cancer has decreased by 30%
- It is estimated that by 2020 oral cancer will surpass cervical cancer as the most common HPV-related cancer
Oral HPV detection can prevent the development of HPV-associated oral cancer.
