The full explanation.

The simple version

The cervix is the lower part of the uterus. Early cervical cancer often causes no symptoms, which is why screening is so important. When symptoms do appear, abnormal vaginal bleeding is one of the most common.

Possible signs

Symptoms, when present, can include:

  • Abnormal vaginal bleeding — between periods, after sex, or after menopause
  • Unusual vaginal discharge
  • Pelvic pain or pain during sex

Screening finds it early

The Pap test and HPV test can find abnormal cervical cells before they become cancer, or find cancer early. Almost all cervical cancer is caused by HPV, and the HPV vaccine lowers the risk.

Screening can find cervical changes before they ever become cancer.

When to see a doctor

See a doctor for abnormal vaginal bleeding, bleeding after sex, or unusual discharge, and keep up with recommended cervical screening.
