What are HPV
and Cervical Cancer?
Cervical cancer is a type of anogenital cancer that occurs in the cervix, which is the lower end of the uterus. All women are at risk of cervical cancer, and almost all cervical cancer cases are caused by the human papillomavirus (HPV).1,2
After the first exposure to HPV, it may take 10-15 years for cervical cancer to develop.2 Before becoming cancerous, abnormal cells will begin to form in the cervix. If undetected, the abnormal cells then start to grow and spread, eventually becoming cervical cancer.1
As early-stage cervical cancer usually doesn’t show any symptoms, it can be hard to detect until after the cancer has spread.3 That’s why understanding the risk of cervical cancer is important.
| Asia | ~ 351,720 new cervical cancer cases were diagnosed, and 199,902 deaths were reported in 20204 |
| Worldwide | Cervical cancer is the fourth most common female cancer worldwide, with an estimated 604,000 new cases and 343,000 deaths reported in 20202 |
By knowing your HPV and cervical cancer risk, you can decide if you will benefit from HPV vaccination and regular cervical cancer screenings.
What is HPV?
HPV is the primary cause of cervical cancer. Almost all cases of cervical cancer can be attributed to HPV infection, with HPV types 16 and 18 accounting for about 70% of all cervical cancer cases.5
After HPV types 16 and 18, the 6 most common HPV types worldwide are types 31, 33, 35, 45, 52 and 58, which account for an additional 20% of cervical cancers.5
Most HPV infections, including the types that can cause cancer, may resolve on their own. But for some women, the infection may result in abnormal or cancerous cell changes in the cervix if it becomes chronic.6
HPV infections that last beyond 12 months will increase the likelihood of abnormal changes. If these abnormal changes are not detected early, they may develop into cervical cancer.7
Since an HPV infection often has no symptoms, it can be hard to detect.1 At the same time, a negative HPV test may not mean that the infection has cleared either, as the virus can persist at a low level and cause diseases later in life.8
What are the symptoms of cervical cancer?
Early stages of cervical cancer don’t usually show symptoms and the first signs of cervical cancer may take several years to develop.
However, when symptoms do occur, they may include9:
Vaginal bleeding
after sex
Vaginal bleeding after menopause
Having periods that are heavier or longer than normal
Vaginal discharge that is watery and has a strong odor
Vaginal discharge that Contains blood
Pelvic pain or pain during sex
Advanced cervical cancer that has spread to other parts of the body may include the symptoms of early-stage cervical cancer, along with9:
Difficult or painful bowel movements
Bleeding from the rectum when having a bowel movement
Difficult or painful urination
Blood in the urine
Dull backache
Swelling of the legs
Pain in the abdomen
Feeling Tired
Understanding your risk of HPV can help you decide if you will benefit from regular cervical cancer screenings and detect any signs early.
