Link Between Breast and Ovarian Cancer: Identified Risk Factors
Zippy Take:
Both breast and ovarian cancer share a common bond, primarily due to some wacky genes and a handful of personal factors. Here's the lowdown on their intertwined relationships.
An Unlikely Twosome: Breast and Ovarian Cancer
Turns out, breast cancer and ovarian cancer have more in common than you'd think. They're like the puppies and kittens of the cancer world, having a closer relationship than you probably imagined. And the main culprit? Genetics.
If you've got mutations in the BRCA1 or BRCA2 genes, let's call them thejamin and brangelina of the cancer gene world, you're looking at a significantly increased risk of falling victim to both cancers. Shockingly, around 50% of families with these gene mutations develop both breast and ovarian cancers[1][2].
But wait, there's more! People with either cancer face an increased risk of developing the other, regardless of genes. So, if you've battled breast cancer, keep an eye out for ovarian cancer, and vice versa[3].
The Culprits: Risk Factors Galore
Genes ain't the only game in town when it comes to cancer risk. There's a pantheon of other factors that can boost your chances of developing breast and/or ovarian cancer. Here are the key suspects:
- Family history: If you've got a close relative (your aunt, sister, mom) who's battled either cancer, your risk increases. And if no BRCA mutations have been found, it might still be a good idea to chat with your doctor[1][2].
- Age: As the years tick by, the chances of developing both cancers increase, particularly after menopause for ovarian cancer and in older adulthood for breast cancer[4].
- Reproductive and hormonal factors: Never having been pregnant, not breastfeeding, early menstruation, or a late menopause can all play a part in raising your risk[5].
- Personal and family history: If you've battled breast cancer before, watch out for ovarian cancer (and vice versa). Someeven suggest that ovarian cancer can bump up the risk of breast cancer[3].
- Ethnicity: Certain ethnic groups, such as Ashkenazi Jews, have elevated baseline risks for both cancers[1][2].
- Lifestyle and environmental factors: Obesity and hormone therapy may impact risk, though the connection is complex and context-dependent[2].
The Bright Side: Taking Control
While some factors at play are out of your control, like your personal or family history, there are things you can do to reduce your risk:
- Weight: Achieving and maintaining a moderate weight can help lower your risk[2].
- Exercise: Regular physical activity can help reduce the risk of breast cancer, and there might be a connection with ovarian cancer too[2].
- Alcohol: Limiting alcohol intake can lower the risk of breast cancer[2].
- Oral contraceptives: These might offer some protection against ovarian cancer, although they could slightly increase the risk of breast cancer[2].
The Long and Winding Road: Prognosis and Next Steps
If you're in a high-risk group, your outlook might be relatively good, with 5- and 10-year overall survival rates of around 90%, provided the interval between the two cancers is lengthy. However, ovarian cancer can pop up following breast cancer, and it's often diagnosed at a later stage, which can influence the prognosis[3].
Staying in touch with your healthcare provider and staying vigilant for signs of recurrence or a new cancer are crucial steps in improving outcomes. And, let's not forget about genetics testing, regular screenings, and preventive measures for those at higher risk[3].

- If you've got ovarian cancer, are you more likely to develop other cancers? Yep! Not only breast cancer, but also bladder cancer, bile duct cancer, colorectal cancer, acute leukemia, and melanoma of the eye[6].
- Can breast cancer spread to the ovaries? While it's rare, breast cancer can metastasize to the ovaries, particularly in advanced stages or in individuals with hormone receptor-positive cancers or BRCA mutations[6].
- Who's at high risk of developing ovarian cancer? Women with BRCA1 or BRCA2 gene mutations, a family history of ovarian, breast, or colorectal cancer, Lynch syndrome, endometriosis, never having had a pregnancy, a late first pregnancy, or older age (40+ years) are at increased risk[6].
Let's Sum Up:
So, there you have it! Genes, family history, age, reproductive patterns, personal history, ethnicity, and even lifestyle factors can influence the risk of breast and ovarian cancer. While some things are out of your control, there are steps you can take to reduce your risk and improve your outlook. Be vigilant, and stay in touch with your healthcare provider!

- Women with a family history of breast or ovarian cancer, particularly if no BRCA mutations have been found, may still have an increased risk and should consider discussing this with their doctor.
- For individuals who have undergone treatment for either breast or ovarian cancer, it is crucial to stay vigilant for signs of recurrence or the development of the other cancer.
- Beyond genetics, other lifestyle factors such as obesity, alcohol consumption, and hormone therapy can impact the risk of developing both breast and ovarian cancers.
- While ethnicity may not be directly controllable, certain ethnic groups, such as Ashkenazi Jews, have an elevated baseline risk for both breast and ovarian cancers.
- Regular physical activity, achieving and maintaining a moderate weight, limiting alcohol intake, and considering oral contraceptives can help reduce the risk of developing both breast and ovarian cancers, offering steps for individuals to take control of their health and wellness, particularly in the realm of women's health.
