Ovarian Cancer: Myths vs Facts Everyday Health MenuNewslettersSearch Ovarian Cancer Ovarian Cancer Myths vs Facts The best way to beat ovarian cancer is to know the difference between misconceptions and the facts. Check out these 6 myths, debunked. By Lambeth HochwaldMedically Reviewed by Thomas Urban Marron, MD, PhDReviewed: July 27, 2022Medically ReviewedOvarian cancer is often caught in later, more advanced stages when it has spread and become difficult to treat.Adobe Stock; Everyday HealthHistorically known as a silent killer because early symptoms, like bloating and constipation, may not be associated with severe illness, ovarian cancer affects 21,000 American women annually, according to the Ovarian Cancer Research Alliance and is often diagnosed at a later, less-treatable stage. But beyond its reputation, there are also a lot of misconceptions, says David A. Fishman, MD, a gynecologic oncologist and the director of the cancer center at NewYork-Presbyterian Weill Cornell Medicine in New York City. Here, Dr. Fishman sifts through some of the myths and facts regarding the disease. Myth 1 Ovarian Cancer Symptoms Can Mask Others Fact: The discomfort is real, not vague. It’s more that you can mistake symptoms for other things. “Since your ovaries are surrounded by your bowels and colon, you may think you’re having digestive issues, for instance, if you’re experiencing pelvic pain,” Fishman explains. The solution is to always consider the possibility that the discomfort could be coming from your ovaries. Any pelvic discomfort or pain that lasts for more than a few days should be evaluated, he says. “During an appointment with any healthcare provider, whether it’s your gynecologist or your GI doctor, make sure you ask to have your ovaries evaluated, too.” Myth 2 There s No Way to Prevent Ovarian Cancer Fact: There’s no surefire way to prevent it, says Fishman, but there are certain things you can do to help prevent it. “For example, five years’ use of birth control pills can decrease your risk by 50 percent, even among women who have a mutation, like BRCA1 or BRCA2, that increases the risk of developing ovarian cancer,” he says. “If you’re not trying to get pregnant, taking birth control pills for five years can help.” Myth 3 There s No Definitive Way to Screen for Early-Stage Ovarian Cancer Fact: Actually, an ultrasound can pick up an ovarian mass quite well. The catch: ultrasounds are not used as a screening tool because the disease is relatively rare and the tests are expensive. “Ultrasounds are the best imaging we have to evaluate the ovaries,” he says. But because it costs a lot to screen so many women, insurance companies have yet to offer them as part of routine preventive care, he explains. Myth 4 Women With the BRCA1 and BRCA2 Mutations Have the Highest Ovarian Cancer Risk Fact: Yes and no. The lifetime risk of being diagnosed with ovarian cancer is 1.4 percent for those who do not carry a high-risk mutation. For those who carry the BRCA1 or BRCA2 mutation, the average cumulative risk is 40 to 75 percent, and 11 to 34 percent, respectively. But that’s not the whole story. Experts are learning more and more about inherited mutations as well as acquired mutations. “For example, you can be born without a mutation, but you can be exposed to environmental toxins that cause you to develop one,” says Fishman. “Ultimately, all cancers are due to genetics, but not all genetic mutations are inherited, some are acquired. It’s unique to you.” Myth 5 The CA 125 Blood Test Is a Useful Blood Test to Detect Ovarian Cancer Fact: Not really. Doctors sometimes use this blood test, which measures the amount of a protein called CA-125 in the blood, as a first-pass screen to detect the potential presence of ovarian cancer. But it was never intended to be a diagnostic test, Fishman notes. “There are many different types of ovarian cancer,” he says. “Some types don’t produce that protein. So, its ability to detect early-stage ovarian cancer is less than 50 percent.” Where is it useful? In tracking the status of disease in some people who have already been diagnosed. “That’s what it’s approved for,” he says. Myth 6 Ovarian Cancer Is All About the Ovaries Fact: Not necessarily. There are actually some strong theories that ovarian cancers start in the fallopian tubes and spread to the ovaries, but the connection remains uncertain, says Fishman. He is currently studying whether detecting precancers in the fallopian tubes and treating them will deter ovarian cancer from developing.
