What is cervical cancer?

When cancer starts in the cervix, it is called cervical cancer. The cervix connects the vagina (birth canal) to the upper part of the uterus. The uterus (or womb) is where a baby grows when a woman is pregnant.

All women are at risk for cervical cancer. It occurs most often in women over age 30. Long-lasting infection with certain types of
HPV is the main cause of cervical cancer. HPV is a common virus that is passed from one person to another during sex. At least half of sexually active people will have HPV at some point in their lives, but few women will get cervical cancer.

Screening tests and the HPV vaccine can help prevent cervical cancer. When cervical cancer is found early, it is highly treatable and associated with long survival and good quality of life.

Risk factors

Almost all cervical cancers are caused by HPV, a common virus that can be passed from one person to another during sex. There are many types of HPV. Some HPV types can cause changes on a woman’s cervix that can lead to cervical cancer over time, while other types can cause genital or skin warts.

HPV usually causes no symptoms so you can’t tell that you have it. For most women, HPV will go away on its own; however, if it does not, there is a chance that over time it may cause cervical cancer.

Other things can increase your risk of cervical cancer—

  • Having HIV (the virus that causes AIDS) or another condition that makes it hard for your body to fight off health problems.
  • Smoking.
  • Using birth control pills for a long time (five or more years).
  • Having given birth to three or more children.
  • Having several sexual partners.

Screening Tests

Two tests can help prevent cervical cancer or find it early—

  • The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately.
  • The HPV test looks for the virus that can cause these cell changes.

HPV Vaccine

The vaccine protects against the types of HPV that most often cause cervical, vaginal, and vulvar cancers.

  • HPV vaccination is recommended for preteens aged 11 to 12 years, but can be given starting at age 9.
  • HPV vaccine also is recommended for everyone through age 26 years, if they are not vaccinated already.
  • HPV vaccination is not recommended for everyone older than age 26 years. However, some adults age 27 through 45 years who are not already vaccinated may decide to get the HPV vaccine after speaking with their doctor about their risk for new HPV infections and the possible benefits of vaccination. HPV vaccination in this age range provides less benefit, as more people have already been exposed to HPV.

If vaccination is started before age 15, a two-dose schedule is recommended, with the doses given 6 to 12 months apart. For people who start the series after their 15th birthday, the vaccine is given in a series of three shots.

HPV vaccination prevents new HPV infections, but does not treat existing infections or diseases. This is why the HPV vaccine works best when given before any exposure to HPV. You should get screened for cervical cancer regularly, even if you received an HPV vaccine.

Symptoms

Early on, cervical cancer may not cause signs and symptoms. Advanced cervical cancer may cause bleeding or discharge from the vagina that is not normal for you, such as bleeding after sex. If you have any of these signs, see your doctor. They may be caused by something other than cancer, but the only way to know is to see your doctor.

Diagnosis

If your doctor says that you have cervical cancer, ask to be referred to a gynecologic oncologist—a doctor who has been trained to treat cancers of a woman’s reproductive system. This doctor will work with you to create a treatment plan.

Types of Treatment

Cervical cancer is treated in several ways. It depends on the kind of cervical cancer and how far it has spread. Treatments include surgery, chemotherapy, and radiation therapy.

  • Surgery: Doctors remove cancer tissue in an operation.
  • Chemotherapy: Using special medicines to shrink or kill the cancer. The drugs can be pills you take or medicines given in your veins, or sometimes both.
  • Radiation: Using high-energy rays (similar to X-rays) to kill the cancer.
