This cancer could affect YOU!
- Cervical cancer is a cancer that develops at the entrance to the uterus, called the cervix.In Japan, approximately 11,000 women are diagnosed with cervical cancer every year and about 2,900 women die from it.
- The frequency of cervical cancer is relatively high in younger women. It starts to increase in women in their 20s and around 1,000 women each year have to have their uterus removed by the age of 40 due to treatment for cervical cancer. In Japan, cervical cancer is the second leading cause of cancer death among women aged 25 to 40.
- While the HPV vaccine is expected to protect against cervical cancer by preventing infection with HPV, some HPV infections cannot be prevented by the vaccine. In order to be able to detect and treat the cancer early, it is important for women to attend cervical screening once every two years from the age of 20.
