About cervical cancer_and_hpvPresentation Transcript
What is cervical cancer?
Cervical cancer appears in cervix uteri or cervical area. It may present with pelvic pain and vaginal bleeding, especially after intercourse, but symptoms may be absent until the cancer is in its advanced stages. The early stages of cervical cancer may be completely asymptomatic, so cervical cancers usually are diagnosed at a much later stage, after the cancer has spread to other parts of the body and becomes more difficult to treat. The early stage cervical cancer can only be discovered by diagnostic test.
What is HPV?
Human papillomavirus (HPV) is a virus that capable of infecting humans.
It affects the growth of the cervical cells and causes nearly all cases of cervical cancer.
HPV types that are more likely to lead to the development of cancer are referred to as “high-risk.”
Some types of HPV are referred to as “low-risk” viruses because they rarely cause lesions that develop into cancer, but some of them will cause genital warts.
By the age of 50, about 80% of women will have had genital HPV infection.
How common is cervical cancer and Genital warts?
Cervical cancer is the 2nd-most-common type of cancer that affects women.
About 1 new case of cervical cancer is being diagnosed 1 minute around the world. In 2008, it was estimated that there were 473,000 cases of cervical cancer, and 253,500 deaths per year.
Genital warts is 60 times more prevalent than cervical cancer in the world, i.e. about one new case of genital warts is being diagnosed every single second.
How can HPV be transmitted? HPV can be transmitted through vaginal, oral and anal sex. Rarely, HPV can be spread by indirect contact, for example, using a towel after someone who is infected.
I only have one sexual partner. Will I be susceptible to HPV infection? Yes. According to studies on young female in UK and USA, including college students, around 50% will be infected by HPV within 5 years after sexual experience, even with a single partner.
How do I know if I have HPV? When you infected by HPV, there will not be any symptoms. The infection can only be discovered by diagnostic test.
