Connection between Breast and Ovarian Cancer: Causes and Risk Factors
Let's Talk About the Link Between Breast and Ovarian Cancer
There's no denying it - breast cancer and ovarian cancer share a tight bond, mostly due to genetic factors. And if you got got the wrong genes, like BRCA1 or BRCA2, you might be in for a double whammy.
But let's break it down. You see, both breast and ovarian cancers share some underlying genetic risk factors. If you've got those risk factors, you might have an increased risk for developing both cancers.
Can't control some of those genetic factors, but others? You bet. You can do your part by maintaining a healthy weight and keeping active. Overweight or obesity, for instance, can increase your risk of breast cancer. And while the link is less clear for ovarian cancer, staying fit can only help.
Now, what about the elephant in the room - those with a history of breast or ovarian cancer? You're definitely at a higher risk for developing the other one, especially if these cancers are linked to genetic mutations like BRCA1 or BRCA2. But here's the good news - you can't change that risk factor, but you can manage it.
Your healthcare team can suggest more frequent and thorough screenings, like mammograms, breast MRI scans, pelvic exams, and transvaginal ultrasounds, to catch any new cancers early. Genetic testing, too, can help you make informed decisions about monitoring and prevention. And for those carrying genetic mutations, doctors might consider additional options like prophylactic surgeries.
So, remember - some risk factors are out of your control. But by adopting a healthy lifestyle, staying informed, and working with your healthcare team, you can take charge of your health and reduce your risk of breast and ovarian cancer.
Genes are Key: Understanding Risk Factors
Mutations in the BRCA1 and BRCA2 genes are the most significant shared risk factors. Research suggests that around 45% of families with ovarian and breast cancer have BRCA1 gene mutations, while around 15% have BRCA2 mutations[1].
But wait, there's more. A family history of either cancer, older age, overweight or obesity, having a first child over 30, never having children, not breastfeeding, and hormone therapy after menopause can also increase your risk[1][2][3].
But don't fret too much - many people with these risk factors never develop cancer. Being informed and proactive is key!
Keep an Eye Out: Symptoms to Watch For
Be vigilant about changes in your body, as early detection is crucial for improving outcomes. Here are some warning signs that may indicate breast or ovarian cancer:
- Breast changes, like lumps, nipple discharge, or skin changes
- Ovarian symptoms, such as bloating, pelvic pain, and unusual bowel habits
Remember, if you have a personal or family history of breast or ovarian cancer, it's essential to stay on the lookout for signs of recurrence or a second cancer after a previous diagnosis.
Resources and FAQs
- Can those with ovarian cancer develop other cancers? Yes, they may face an increased risk of several cancers, including breast, bladder, bile duct, colorectal, acute leukemia, and melanoma of the eye[1].
- Can breast cancer spread to the ovaries? While it's relatively uncommon, breast cancer can metastasize (spread) to the ovaries. It may be more likely in breast cancers that are hormone receptor-positive or in those with BRCA mutations[1].
- Who is at high risk for ovarian cancer? Those who have BRCA1 or BRCA2 gene mutations, a family history of ovarian, breast, or colorectal cancer, Lynch syndrome, endometriosis, never been pregnant, had a late first pregnancy, or are over 40 years old may be at higher risk[1].

- A significant shared risk factor between breast and ovarian cancer is the presence of mutations in the BRCA1 and BRCA2 genes, with around 45% of families with both cancers having BRCA1 gene mutations and about 15% having BRCA2 mutations.
- Other risk factors for both breast and ovarian cancer include a family history of either cancer, older age, overweight or obesity, having a first child over 30, never having children, not breastfeeding, and hormone therapy after menopause.
- While it's relatively uncommon, breast cancer can metastasize (spread) to the ovaries, particularly in breast cancers that are hormone receptor-positive or in those with BRCA mutations.
- Those who have BRCA1 or BRCA2 gene mutations, a family history of ovarian, breast, or colorectal cancer, Lynch syndrome, endometriosis, never been pregnant, had a late first pregnancy, or are over 40 years old may be at higher risk for ovarian cancer.
- People with these risk factors for breast and ovarian cancer should be vigilant about changes in their bodies and seek medical attention if they notice signs such as breast changes, like lumps, nipple discharge, or skin changes, or ovarian symptoms, such as bloating, pelvic pain, and unusual bowel habits.
- If you have a personal or family history of breast or ovarian cancer, it's essential to stay on the lookout for signs of recurrence or a second cancer after a previous diagnosis, and to work with your healthcare team to manage your risk through more frequent and thorough screenings, genetic testing, and preserving a healthy lifestyle.
