What You Need to Know About Preventing Gynecologic Cancers – Curetoday.com

Knowing your family history is the first preventative step any woman can take to avoid a diagnosis of ovarian cancer.

BY Dr. Gizelka David-West

As a gynecologic oncologist, this is an all too familiar conversation. Ovarian cancer is the fifth leading cause of cancer death in women, making it the deadliest of all gynecologic cancers with no screening tool. These facts are exactly why we advocate for preventative measures for ovarian cancer and the four other gynecologic cancers cervical, uterine, vaginal and vulvar.

Knowing your family history is the first preventative step any woman can take to avoid a diagnosis of ovarian cancer. Twenty to 25% of all cases of ovarian cancer are due to genetic mutations, with BRCA mutations accounting for about 16% of those cases and 5% being other mutations. Harboring a mutation in the BRCA 1 or BRCA2 gene increases a womans risk of developing ovarian cancer by 60% or 40%, respectively. With genetic testing and a confirmed mutation, we can prevent this disease with risk reducing surgeries that remove the fallopian tubes and ovaries, dramatically reducing this risk of cancer. Knowing your genetic profile can also help prevent recurrence of this deadly disease with targeted therapies that have been proven to prolong life without disease recurrence or progression.

Next up on the list of gynecologic cancers are three of the five, which fall into the category of HPV related cancers cervical, vulvar and vaginal cancers. With the development of the HPV vaccine, now available to women up to the age of 45, we can prevent these cancers and have the potential to eradicate them. Seems like a no brainer to call your local gynecologist and get vaccinated not only does the vaccine prevent these cancers, it prevents and can help treat the pre-cancer called dysplasia, which transforms into cancer of these organs if left untreated over time.

Finally, uterine cancer, a subset of which is endometrial cancer, is the most common of the gynecologic cancers. Although it is expected that 62,000 new cases of endometrial cancer will be diagnosed this year, it can potentially be prevented. A major risk factor for endometrial cancer is higher than normal estrogen stimulating the uterus this can come from our fat tissue and women who are overweight or obese, have a much higher risk of developing this cancer. Additionally, extra estrogen exposure can come from hormone replacement therapy, which some women may start using in the peri- and post-menopause phase of life. Genetics also play a role in uterine cancer and women with a confirmed diagnosis of Lynch Syndrome have up to a 60% risk of developing this cancer.

I focus my prevention strategies for endometrial cancer on encouraging my patients to maintain a normal range body mass index with regular healthy diet and exercise. If exploring hormone replacement therapy to use with caution the lowest doses for the shortest amount of time. And of course, genetic testing is recommended if strong personal or family history suggestive of Lynch Syndrome.

I hope this post has been informative and provides tools to help you share knowledge this month on preventing gynecologic cancers! To learn more about gynecologic cancers, genetics, clinical trials and survivorship, I encourage you to visit the Foundation for Womens Cancer website and share what you learn with your family, friends and colleagues.
