Cervical cancer is cancer of the cervix (the lower part of the uterus that connects to the vagina). Cervical cancer usually forms slowly over many years, but occasionally it happens faster.

The purpose of the Papanicolaou test (Pap test) is to detect abnormal cells in the cervix, and the HPV test looks for the human papillomavirus that can cause these cell changes. When abnormal cells are found and treated early, cervical cancer can be prevented or cured.

These two screening tests, used as recommended by your health care provider, can help prevent cervical cancer or find it early.

Prevention

Most cervical cancer is caused by a virus called the human papillomavirus, or HPV, which is spread through sexual contact. Abnormal cervical cells rarely cause symptoms, but detection of the earliest changes leading to cancer development is possible through the use of Pap and/or HPV testing.

HPV is a group of more than 100 related viruses.

Screening and Detection

Cervical cancer is highly curable when found and treated early. Almost all cervical cancers are caused by HPV. 

  • All women: Know the benefits, limitations and potential harms linked to cervical cancer screening, and be aware of the risk factors linked to cervical cancer.
  • Women aged 21 to 29: Schedule regular Pap tests and follow your provider’s screening recommendations based on those results.
  • Women aged 30 to 65: Based on your testing history, you may only need a Pap test and/or HPV test every three to five years.
  • Women over 65: You may no longer need additional screenings based on your testing history.
Individuals at Increased Risk

Infection with HPV may cause cells in the cervix to grow out of control and become cancerous. Not every HPV infection is destined to become cervical cancer. Many HPV infections resolve without treatment.

  • Smoking increases the risk of cervical cancer as well as advancing age since cervical cancer grows very slowly over time.
  • If a mother or sister has cervical cancer, a woman’s chances of developing the disease increases by two to three times.
