Who Is at Risk for HPV?

HPV is so common that most people who have ever had sex — both women and men — will get the virus at some point in life. Because HPV can linger quietly, it’s possible to carry the infection even if it has been years since you had sex. Condoms can lower your risk of getting HPV, but they do not fully protect against the virus. HPV is also linked to cancers of the vulva, vagina, penis, and to anal and oral cancers in both sexes.

How HPV Causes Cervical Cancer

If one of the high-risk strains of HPV lingers in the body, it can cause abnormal cells to develop in the cervix. These precancerous changes do not mean that you have cervical cancer. But over time, the abnormal cells may give way to cancer cells. Once cancer appears, it tends to spread in the cervix and surrounding areas.

What Else Raises Your Risk?

Hispanic and African-American women have higher rates of cervical cancer than white women. The risk is also higher in infected women who:

• Smoke
• Have many children
• Use birth control pills for a long time
• Are HIV positive or have a weakened immune system

Early Detection: Pap Test

The Pap test is one of the great success stories in early detection. A swab of the cervix can reveal abnormal cells, often before cancer appears. At age 21, women should start having a Pap test every three years. From age 30 to 65, women who get both a Pap test and an HPV test can go up to five years between testing. But women at higher risk may need testing more often, so it’s best to check with your doctor. Skipping tests raises your risk for invasive cervical cancer.

Of note: You’ll still need Pap tests after getting the HPV vaccine because it doesn’t prevent all cervical cancers.

What If Your Pap Test Is Abnormal?

If test results show a minor abnormality, you may need a repeat Pap test. Your doctor may schedule a colposcopy — an exam with a lighted magnifying device — to get a better look at any changes in the cervical tissue and also take a sample to be examined under a microscope. If abnormal cells are precancerous, they can then be removed or destroyed. Treatments are highly successful in preventing precancerous cells from developing into cancer.

Early Detection: HPV DNA Test

In some cases, doctors may offer the option of the HPV DNA test in addition to a Pap test. This test checks for the presence of high-risk forms of HPV. It may be used in combination with a Pap test to screen for cervical cancer in women over 30. It may also be recommended for a woman of any age after an abnormal Pap test result.

Diagnosing Cervical Cancer: Biopsy

A biopsy involves the removal of cervical tissue for examination in a lab. A pathologist will check the tissue sample for abnormal changes, precancerous cells, and cancer cells. In most cases, a biopsy takes place in a doctor’s office during a colposcopy. A cone biopsy allows the pathologist to check for abnormal cells beneath the surface of the cervix, but this test may require anesthesia.

Stages of Cervical Cancer

Stage 0 describes cancer cells found only on the surface of the cervix.  More invasive cancers are separated into four stages. Stage I – the cancer has grown beyond the cervix and uterus, but hasn’t spread to the walls of the pelvis or the lower part of the vagina.  Stage II – the cancer has spread beyond the cervix and uterus and possibly to nearby tissues.  A Stage III tumor extends to the lower part of the vagina and may block urine flow. It may have spread to lymph nodes. Stage IV – this is the most advanced stage of cervical cancer. The cancer has spread to nearby organs or other parts of the body.

Treatment: Surgery

If the cancer has not progressed past Stage II, surgery is usually recommended to remove any tissue that might contain cancer. Surgical treatment options vary from cervical conization to simple hysterectomy to radical hysterectomy. A radical hysterectomy includes, the removal of the cervix and uterus as well as some of the surrounding tissue. The surgeon may also remove the fallopian tubes, ovaries, and lymph nodes near the tumor.

Treatment: Radiation

External radiation therapy uses high-energy X-rays to kill cancer cells in a targeted area. It can also help destroy any remaining cancer cells after surgery. Internal radiation, or brachytherapy, uses radioactive material that is inserted into the tumor. Women with cervical cancer are often treated with a combination of radiation and chemotherapy. Side effects can include low blood cell counts, feeling tired, upset stomach, nausea, vomiting, and loose stools.

Treatment: Chemotherapy

Chemotherapy uses drugs to reach cancer wherever it is in the body. When cervical cancer has spread to distant organs, chemotherapy may be the main treatment option. Depending on the specific drugs and dosages, side effects may include fatigue, bruising easily, hair loss, nausea, vomiting, and loss of appetite.

Coping With Cancer Treatments

Cancer treatments may make you tired or uninterested in food. But it’s important to take in enough calories to maintain a healthy weight. Check with a dietitian for tips on eating well during cancer treatment. Staying active is also important. Gentle exercise can increase your energy while reducing nausea and stress. Check with your doctor to find out which activities are appropriate for you.

Cervical Cancer and Fertility

Treatment for cervical cancer often involves removing the uterus and may also involve removing the ovaries, ruling out a future pregnancy. However, if the cancer is caught very early, you still may be able to have children after surgical treatment. A procedure called a radical trachelectomy can remove the cervix and part of the vagina while leaving the majority of the uterus intact.

Survival Rates for Cervical Cancer

The odds of surviving cervical cancer are tied to how early it’s found.About 66% of women overall will survive for at least five years after diagnosis. But statistics don’t predict how well any one individual will respond to treatment.

Vaccine to Help Prevent Cervical Cancer

Vaccines are now available to ward off the two types of HPV most strongly linked to cervical cancer. Both Cervarix and Gardasil require three doses over a 6 month period for people age 15 and older.  Children ages 9 – 14 years should get 2 doses 6 – 12 months apart. Studies suggest the vaccines are effective at preventing chronic infections with the two types of HPV that cause 70% of cervical cancers. Gardasil also protects against two types of HPV that cause genital warts. Gardasil-9 has been proven as effective as Gardasil for the prevention of diseases caused by the four shared HPV types (6, 11, 16, and 18). It also protects against five other strains of HPV virus (31, 33, 45, 52, and 58).
