Connection Between Breast and Ovarian Cancer: Key Links and Risk Factors
Heads Up: Breast and Ovarian Cancer Connection
Got a pair of cancers on your mind? Let's talk about breast and ovarian cancers, two notorious health issues that share some sinister ties, particularly when it comes to genes.
These two types of cancer often go hand-in-hand, thanks to their shared genetic risk factors. In fact, if you've got one, chances are you may have an increased risk for the other. But here's the silver lining: some of these risk factors are actually manageable.
A Tangled Web of Genes
The link between these cancers can be traced back to certain genetic mutations, particularly the BRCA1 and BRCA2 genes. Sounds techy, we know, but it's all about the DNA code. Each gene is like a blueprint for the body, and mutations in these blueprints can lead to some serious health consequences.
Close to 40% of families with ovarian and breast cancer have mutations in the BRCA1 gene, while about 20% carry BRCA2 mutations[4]. So, if you've got a family history of either cancer, it might be worth considering genetic testing to get a clearer picture of your own risk.
Risk Factors: What's in Your Control?
Apart from genetics, other risk factors for both cancers include:
- A family history of either cancer
- Older age, with ovarian cancer typically striking people over 40 years old, while breast cancer tends to appear in those ages 55 years or older
- Overweight or obesity
- Having a first child after 30
- Never having children
- Not breastfeeding
- Hormone therapy after menopause
Take heart, though. Some of these risk factors can be influenced or even minimized. For example, managing your weight, getting regular exercise, limiting alcohol, and discussing contraception options with your doctor are all strategies that can help lower your risk.
Reducing the Risk: Tackling the Unchangeable
Some risk factors are out of our control, like a personal or family history of breast or ovarian cancer. To tackle these unchangeable risk factors, focus on careful monitoring, lifestyle changes, and, in some cases, preventive medical procedures. If you've had either of these cancers before, it's vital to stay vigilant for signs of recurrence or a second cancer.
Healthcare professionals may suggest more frequent and thorough screenings for those at higher risk. This can include regular mammograms, breast MRI scans, pelvic exams, transvaginal ultrasounds, and CA-125 blood tests. Genetic testing is also a key strategy for monitoring and prevention. For those carrying genetic mutations, doctors may consider additional options such as prophylactic surgeries.
The Bright Side: A (Relative) Silver Lining
A 2020 observational study suggests that people with both primary breast cancer and primary ovarian cancer have a relatively favorable outlook, with 5- and 10-year overall survival rates of around 90%[1]. The outlook is generally more positive when the interval between the two diseases is longer.
Remember, though, that a variety of factors can impact your personal outlook. Speak with your healthcare team for more information about your individual outlook.
When to Speak Up
If signs or symptoms of breast or ovarian cancer appear, especially with a personal or family history of these diseases, don't hesitate to speak with a doctor. Early detection and prompt treatment are crucial for improving outcomes.

- In the realm of oncology, breast and ovarian cancers hold a significant connection, particularly in regard to their shared genetic risk factors, such as BRCA1 and BRCA2 genes.
- Should you have a family history of either breast or ovarian cancer, there's a chance you may have an increased risk for the other, making genetic testing merit consideration.
- Besides genetics, other risk factors for both cancers include factors like age, weight, reproductive history, and hormone therapy during menopause, which can be influenced or minimized through healthy lifestyle choices and medical advice.
- For those with a personal or family history of breast or ovarian cancer, careful monitoring, lifestyle changes, and preventive medical procedures are crucial to mitigate unchangeable risk factors.
- In cases where genetic mutations have been identified, doctors may suggest additional options such as prophylactic surgeries.
- While a family history of breast or ovarian cancer may present concerns, early detection and prompt treatment provide a relative silver lining, with long-term overall survival rates of approximately 90% for patients diagnosed with both primary breast cancer and primary ovarian cancer.
