Connection Between Breast and Ovarian Cancer: Underlying Links and Key Risk Factors
Breast cancer and ovarian cancer aren't strangers to each other, thanks to their shared genetic ties. These two cancers are strongly linked, particularly in individuals who carry mutations in the BRCA1 and BRCA2 genes.
Let's face it, people with these genetic mutations have a much higher probability of brawling with both breast and ovarian cancer, with as many as 60-70% developing breast cancer and 40-50% developing ovarian cancer - a pretty staggering stat.
But cancer isn't a solitary bout; it often comes in pairs, and a history of one type increases the risk of the other. If you've had breast cancer, you're more likely to find trouble with ovarian cancer, especially if your battle with the breast involved genetic mutations in BRCA1 or BRCA2. However, it's the underlying genetics that boost your risk, not the illness itself.
Research has shown that people with breast cancer are roughly twice as likely to develop primary ovarian cancer. On the flip side, an ovarian cancer survivor might see a 1.6-fold increase in breast cancer risk, although the exact risk varies with time from the initial diagnosis.
Interestingly, ovarian cancer patients may also face a hike in breast cancer risk due to genetic mutations, just like their breast cancer counterparts.
So, what other risk factors are these cancers huddled around? Well, aside from those pesky genetic mutations, other shared offenders include:
- Age: Both cancers tend to strike after 40, with ovarian cancer nabbing the older advocate.
- Weight: Keeping weight in check is crucial. Overweight or obesity may cause hormonal imbalances that increase the risk of breast cancer.
- Pregnancy: Having a first child over 30 and never having kids seems to boost the risk, too.
- Lack of breastfeeding: Breastfeeding may offer some protective benefits.
- Hormone therapy: Hormone therapy after menopause might also play a role in upping the risk.
Fortunately, some risk factors can be modified. Maintaining a moderate weight, regular exercise, reducing alcohol intake, and pondering contraception options can all help minimize the risk.
Now, if you've tussled with either of these cancers before, managing your risk involves careful monitoring, lifestyle adjustments, and, at times, preventive medical procedures. Regular check-ups, mammograms, breast MRI scans, pelvic exams, transvaginal ultrasounds, and CA-125 blood tests are some options your healthcare team might suggest. Genetic testing for BRCA1, BRCA2, and other relevant mutations often proves to be the best strategy for monitoring and prevention.
For those carrying genetic mutations, prophylactic surgeries could be an option. These procedures involve removing organs or tissues to stave off the occurrence or dissemination of cancer.
The battle between these two cancers doesn't always end in a knockout. A 2020 study found that people grappling with both primary breast cancer and primary ovarian cancer had a relatively optimistic outlook, with 5- and 10-year overall survival rates hovering around 90%. The outlook is usually brighter when there's a longer gap between the two diagnoses. However, ovarian cancer following breast cancer tends to be diagnosed at a later stage, which can affect survival rates.
Remember, early detection is key, so stay vigilant for signs,particularly if you have a family history of these diseases. Work closely with your healthcare team to devise a strategy that best suits your situation.

Fun facts: People with ovarian cancer may also face an increased risk of bladder, bile duct, colorectal, acute leukemia, and melanoma of the eye. Breast cancer can metastasize (or spread) to the ovaries, although it's relatively rare.
High-risk individuals for ovarian cancer include those with BRCA1 or BRCA2 gene mutations, Lynch syndrome, or endometriosis. People who have never been pregnant, had a late first pregnancy, are over 40, or have a family history of these cancers are also at higher risk.
- People with genetic mutations in the BRCA1 and BRCA2 genes have a higher probability of developing both breast and ovarian cancer.
- Research has shown that those with breast cancer are approximately twice as likely to develop primary ovarian cancer, while an ovarian cancer survivor might see a 1.6-fold increase in breast cancer risk.
- Ovarian cancer patients may also face an increased risk of breast cancer due to genetic mutations, just like their breast cancer counterparts.
- Age, weight, pregnancy history, lack of breastfeeding, hormone therapy, and menopause are other shared risk factors for both breast and ovarian cancer.
- Maintaining a moderate weight, regular exercise, reducing alcohol intake, and considering contraception options can help minimize the risk of these cancers.
- For high-risk individuals, regular check-ups, mammograms, breast MRI scans, pelvic exams, transvaginal ultrasounds, CA-125 blood tests, genetic testing, and, in some cases, prophylactic surgeries are crucial for monitoring and prevention.
