Ovarian Cancer Risk: What To Know If It Runs In Your Family

Ovarian Cancer Risk

Ovarian cancer remains one of the most challenging gynaecological cancers to detect and treat. While there is no definitive way to prevent it, understanding risk factors, particularly familial links, and early symptoms can play a significant role in reducing the overall impact of the disease. With nearly a quarter of ovarian cancers linked to family genetics, it is crucial for women, especially those with a family history, to be aware of their risk and take appropriate steps toward early detection and prevention.

<h2>What is the Role of Genetics in Ovarian Cancer?</h2>

According to medical experts, family history is one of the most significant factors when it comes to <span>ovarian cancer risk</span>. Women with close relatives, such as a mother or sister, who have been diagnosed with ovarian cancer are at a higher likelihood of developing the disease themselves. 

In fact, about 25% of all ovarian cancers are believed to be influenced by genetic mutations, most commonly in the BRCA1 and BRCA2 genes.

Dr. Shaina Bruce, a gynecologic oncologist at the Penn State Cancer Institute, as reported in US News Health highlights the importance of genetic testing for women with a family history of ovarian or breast cancer. “Knowing whether you are at high risk is the first step toward taking measures that can mitigate that increased danger,” she says. 

Genetic testing can reveal whether a woman carries mutations on the BRCA1 or BRCA2 genes, which are known to increase the likelihood of ovarian cancer by 40% and 20%, respectively.

<h2>What to Do If You Test Positive for BRCA Mutations?</h2>

For women who test positive for BRCA1 or BRCA2 mutations, the prospect of developing ovarian cancer becomes more tangible. Dr. Bruce advises that women at an increased risk for ovarian cancer consider surgery to remove their fallopian tubes and ovaries once they have completed their families. 

“This is a common recommendation for women in this high-risk group,” she explains. “Removing the ovaries and fallopian tubes significantly reduces the risk of ovarian cancer but also induces surgical menopause.”

The downside of surgical menopause, particularly for younger women in their 30s and 40s, is the sudden loss of ovarian function, which can lead to various health challenges. “The estrogen your ovaries make is important for protecting your heart, bones, and reducing the risk of dementia,” Dr. Bruce notes. 

However, the procedure has its advantages, with studies showing that more than 80% of ovarian cancers actually originate in the fallopian tubes.

Historically, women were advised to remove both their ovaries and fallopian tubes as a preventive measure against ovarian cancer. However, in recent years, medical science has evolved, with studies suggesting less invasive options. Dr. Bruce mentions that Penn State is currently participating in a study comparing the removal of just the fallopian tubes in women with BRCA1 mutations, while leaving the ovaries intact for a later procedure. 

Moreover, for women already planning to undergo sterilisation surgery, commonly known as "getting your tubes tied," the option to remove the fallopian tubes altogether is now being discussed as a preventative measure against ovarian cancer.

Though the surgery is minimally invasive, typically involving three small incisions, Dr. Bruce emphasises that it is still a significant decision. “Most women recover within a couple of weeks, but some may prefer to delay the surgery until they have finished having children.” In such cases, regular screening through transvaginal ultrasounds and blood tests may be recommended to monitor any early signs of ovarian cancer.

Screening for ovarian cancer is not generally recommended for women unless they have a known genetic predisposition to the disease. This is primarily because ovarian cancer symptoms are often vague and can be easily mistaken for other conditions. However, for women with BRCA mutations, screening can provide a form of early detection until they are ready for risk-reducing surgery.

For women with BRCA1 mutations, surgery is usually recommended between the ages of 35 to 40, whereas those with BRCA2 mutations are advised to wait until they are between 40 to 45 years old. “If a patient is younger than the recommended age for surgery, screening with ultrasounds and blood tests is a safe interim option,” explains Dr. Bruce.

<h2>Other Risk Factors for Ovarian Cancer</h2>

While genetics play a significant role, there are several other factors that may increase a woman’s risk of developing ovarian cancer. Dr. Bruce points out the following:

<strong>Hormone replacement therapy: </strong>Women who undergo hormone replacement therapy after menopause may be at a higher risk.

Never having been pregnant: Women who have never carried a pregnancy to term are at a slightly higher risk.

Endometriosis: This condition, characterised by the growth of tissue similar to the lining of the uterus outside the uterine cavity, is also linked to an increased risk of ovarian cancer.

<h2>Simple Ways to Lower Your Ovarian <span rel="noindex">Cancer Risk</span></h2>

<ul><li>Include plenty of fruits, vegetables, and whole grains in your meals to boost overall health.</li><li>Regular exercise can help lower your risk by promoting a healthy weight.</li><li>Breastfeeding reduces ovulation, which may decrease ovarian cancer risk.</li><li>They can lower the risk by stopping ovulation for extended periods.</li><li>Awareness of your genetic predisposition can help you take proactive measures.</li></ul>

While surgery may not be an easy choice, advances in medical science are offering more options than ever before. Whether it’s genetic testing, screening, or risk-reducing surgery, knowing your options could be the key to beating ovarian cancer before it begins.
