Cervical Cancer: 4 Risks You Don't Know Published Jan. 8, 2013 319th Air Base Wing Public Affairs Office GRAND FORKS AIR FORCE BASE, N.D. -- TriWest healthcare officials say that getting regular Pap tests is the number one way to protect against cervical cancer, but warn that some may still be at high risk. Cervical cancer occurs most often in women older than 30 years old, according to the Centers for Disease Control and Prevention, and it used to be the leading cause of cancer death for American women. However, over the past 40 years, the number of deaths has dropped significantly thanks in large to the Pap test, according to a TriWest Healthcare Alliance news release. A few factors can increase your risk for cervical cancer and some are not well known. According to TriWest, these include: High number of full-term pregnancies: According to the National Cancer Institute, women who've had seven or more full-term pregnancies could have an increased risk of cervical cancer. The CDC lists that number as three or more children. Long-term use of birth control pills: Women who have used "The Pill" for five years or more have a greater risk of cervical cancer than women who don't use oral contraceptives, experts agree. Smoking: This is perhaps one of the greatest preventable risk factors of cervical cancer. Quitting smoking can cut your risk in half. HPV: Not to be confused with HIV ... HPV stands for Human Papillomavirus, a common sexually transmitted virus. The CDC says that almost all cervical cancers are caused by HPV. Luckily, there is a vaccine, and it's covered by TRICARE. Above all else, getting regular Pap tests remains the number one way to detect cervical cancer early enough for successful treatment. TRICARE covers Pap testing every year beginning at age 18 (or younger if sexually active), according to TriWest. Then, after three consecutive normal tests, TRICARE will cover a Pap test every three years, unless recommended otherwise by the doctor.
