Connection between Breast and Ovarian Cancer: Identified Links and Key Risk Factors

Down the DNA Tunnel: Understanding the Link Between Breast and Ovarian Cancers
There's a robust genetic link between breast cancer and ovarian cancer, and it all comes down to a few key players, primarily the BRCA1 and BRCA2 genes.
Both types of cancer share common underlying genetic risk factors. If these risk factors are present, individuals may face a heightened risk of developing both cancers.
Age, weight, and reproductive history are other factors shared by breast and ovarian cancers. Some of these factors might be within our control for management, like maintaining a moderate weight through diet and exercise.
Breast Cancer and Ovarian Cancer: Fueling Each Other's Growth?
There's evidence to suggest that having breast cancer can up the likelihood of developing ovarian cancer [Source]. This correlation is particularly pronounced in breast cancers associated with genetic mutations in BRCA1 or BRCA2. However, the increased risk isn't due to the disease itself, but rather the underlying genetic factors.
Research points to a doubled risk for women with breast cancer in developing subsequent primary ovarian cancer [Source]. On the flip side, women with ovarian cancer face a 1.6-fold increased risk for breast cancer, though the specifics can vary depending on the time since their initial diagnosis.
Women with ovarian cancer aren't immune to breast cancer either, with genetic mutations playing a part in these cases as well.
Other Peculiar Suspects: Breast and Ovarian Cancer Shared Risk Factors
Mutations in the BRCA1 and BRCA2 genes are crucial shared risk factors, with roughly 30% of families with both breast and ovarian cancer carrying BRCA1 mutations and about 20% harboring BRCA2 mutations [Source].
Other risk factors linking breast and ovarian cancers might include:
- A family history of either cancer
- Advanced age, with ovarian cancer typically striking women over 40, and breast cancer prevalent in women ages 55 and up
- Weight: Being overweight or obese can increase the risk of both cancers
- An initial pregnancy beyond the age of 30
- Never having children
- Lack of breastfeeding
- Post-menopausal hormone therapy
Reducing the Risk: Tips and Tricks
Some risk factors, such as having had breast or ovarian cancer before, are out of our control. However, careful monitoring, lifestyle changes, and medical procedures can help manage the unchangeable.
Those with a history of breast or ovarian cancer might benefit from more frequent and thorough screenings to catch any new cancers early. Possible screening methods include:
- Routine mammograms
- Breast MRI scans
- Pelvic exams
- Transvaginal ultrasounds
- CA-125 blood tests
Genetic testing for BRCA1, BRCA2, and other relevant mutations is an effective means for monitoring and prevention.
For carrying genetic mutations, doctors might consider additional measures like prophylactic surgeries to prevent the occurrence or spread of cancer.
Modifiable Risk Factors: A Few Things You Can Control
Changeable risk factors include:
- Weight: Maintaining a moderate weight decreases the risk of both breast and ovarian cancer
- Exercise: Regular physical activity lowers the risk of breast cancer; limited evidence suggests auto-gettering benefits for ovarian cancer too
- Alcohol: Reducing alcohol consumption decreases the risk of breast cancer; the risk rises with greater alcohol intake, so you may want to chat with a healthcare provider about strategies for limiting alcohol
- Birth Control:Pill might protect against ovarian cancer, though it could slightly increase the risk of breast cancer; consult a doctor to weigh the risks based on your individual circumstances
The Outlook: A Bumpy Road Ahead, but Hope Remains
A recent study indicates that people diagnosed with both breast and ovarian cancer have a somewhat promising outlook, with 5- and 10-year overall survival rates of around 90% [Source].
The survival odds tend to be better when the gap between the two cancers is substantial. However, ovarian cancer following breast cancer is often diagnosed at a later stage, which can negatively impact survival.
A person's age during their first cancer diagnosis and the duration between the two cancers are significant predictors of overall survival.
Discuss your individual outlook with your healthcare team if you have concerns.
When to Consult a Doctor
For women with a history of breast or ovarian cancer, it's crucial to stay vigilant for signs of recurrence or a second cancer. Early detection and timely treatment are vital in improving outcomes.

Frequently Asked Questions
- Bladder Cancer and Melanoma of the Eye: People with ovarian cancer may face an increased risk of additional cancers, such as bladder cancer and melanoma of the eye.
- Metastasis: Breast cancer can spread to the ovaries, although this is somewhat uncommon, particularly in advanced stages of breast cancer.
- High-Risk People: Women at higher risk for ovarian cancer might be 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
- Advanced age over 40 years
In Quite a Pickle: Summing Up
The connection between breast cancer and ovarian cancer is multifaceted, with a strong focus on genetic mutations in the BRCA1 and BRCA2 genes. People with genetic mutations face significantly higher risks of both cancers.
Lifestyle factors such as maintaining a healthy weight, regular exercise, limiting alcohol consumption, and potentially using birth control might help reduce the risk.
In cases of genetic mutations, genetic testing, regular screening, careful monitoring, and preventative measures can be beneficial.
Stay informed, stay vigilant, and remember that every personal situation is unique. Consult with your healthcare team regularly to ensure best outcomes.
- Individuals with breast cancer might have a higher likelihood of developing ovarian cancer, particularly those with associated genetic mutations in BRCA1 or BRCA2.
- Women diagnosed with ovarian cancer are not immune to subsequent breast cancer, with genetic mutations playing a role in these instances as well.
- Shared risk factors between breast and ovarian cancers include mutations in the BRCA1 and BRCA2 genes, family history of either cancer, advanced age, weight, initial pregnancy beyond age 30, never having children, lack of breastfeeding, and post-menopausal hormone therapy.
- To manage these unchangeable risks, individuals with a history of breast or ovarian cancer may benefit from more frequent and thorough screenings, including mammograms, breast MRI scans, pelvic exams, transvaginal ultrasounds, CA-125 blood tests, and genetic testing for relevant mutations.
- Modifiable risk factors include maintaining a moderate weight, regular exercise, limiting alcohol consumption, and potentially using birth control to help reduce the risk of both breast and ovarian cancers.
- People diagnosed with both breast and ovarian cancer have a somewhat promising outlook, with 5- and 10-year overall survival rates around 90%, but the outlook depends on the individual's age during their first cancer diagnosis and the time between the two cancers. For women with a history of breast or ovarian cancer, staying vigilant for signs of recurrence or a second cancer and early detection are crucial in improving outcomes.
