Link Between Breast and Ovarian Cancer, Potential Risk Factors
Rewritten Article:
Check out the lowdown on the connection between breast cancer and ovarian cancer – it's all about genetics, baby!
These two types of cancer share some common risk factors that could up your ante for both diseases. If you've got them, watch out!
Do Breast and Ovarian Cancer Increase Each Other's Risks?
Here's the deal: if you've battled breast cancer, you might be more likely to develop ovarian cancer later down the road. This risk is particularly high if your breast cancer has links to genetic mutations like BRCA1 or BRCA2. But don't freak out – this increased risk is mostly due to those underlying genetic factors, not the cancer itself.
You might be shocked to hear that ovarian cancer patients may also have a slightly increased risk of breast cancer. Once again, genetics play a significant role.
According to the heavyweights in the medical field, people with breast cancer are about twice as likely to develop a subsequent primary ovarian cancer. On the other hand, those with ovarian cancer have a 1.6-fold increased risk of subsequent breast cancer, but that risk varies depending on when they were initially diagnosed.
Other Risk Factors for Breast & Ovarian Cancers
While genetic mutations are the most significant shared risk factors, there are other factors to consider:
- A family history of either cancer. Keep an eye on your family's medical history!
- Age: As you get older, your chances of developing both cancers increase. Ovarian cancer typically occurs in women over 40 years old, while breast cancer strikes those 55 years or older.
- Weight: Being overweight or obese can elevate your risk of both cancers. Maintaining a moderate weight is crucial.
- Reproductive History: Factors like having a child later in life, never having children, and not breastfeeding might also play a role.
- Hormone Therapy: Hormone therapy taken after menopause could potentially boost your chances of breast cancer.
Reducing Your Risks
Although some risk factors are non-negotiable, you can manage others to decrease your chances of getting breast or ovarian cancer.
If you have a history of either cancer, your healthcare team will work with you to monitor new developments, recommend lifestyle changes, and discuss preventative measures. This might include undergoing regular:
- Mammograms
- Breast MRI scans
- Pelvic exams
- Transvaginal ultrasounds
- CA-125 blood tests
Genetic testing for BRCA1, BRCA2, and other relevant mutations could be your best bet for early detection and prevention.
Individuals carrying genetic mutations may also consider additional options like prophylactic surgeries to prevent the occurrence or spread of cancer.
Controllable Risk Factors
Here's where you come in: lowering your risk of breast and ovarian cancer is possible!
- Weight: Maintaining a healthy weight can help reduce both cancer risks. Extra pounds can lead to higher estrogen levels, which can up your chances of breast cancer.
- Exercise: Regular physical activity reduces breast cancer risk and could also benefit ovarian cancer prevention (though evidence is limited). Exercise helps maintain a healthy weight and may have direct anti-cancer effects.
- Alcohol: Cutting back on alcohol lowers breast cancer risk. The risk increases with the amount you drink, so it's recommended to limit your intake.
- Birth Control: Oral contraceptives might protect against ovarian cancer, but they may slightly raise your risk of breast cancer. It's essential to discuss contraception options with your healthcare provider to assess risks based on your personal situation.
Outlook
Research suggests people with both primary breast cancer and primary ovarian cancer have a relatively optimistic prognosis, with 5- and 10-year overall survival rates around 90%.
The outlook is generally brighter when the interval between the cancers is longer. However, ovarian cancer following breast cancer often occurs later, which can impact survival.
Your age at your initial cancer diagnosis and the time between the two cancers are key predictors of overall survival. Remember, every case is unique, so speak with your healthcare team for more information about your individual outlook.
When to Consult a Doctor
Stay vigilant for signs of either breast or ovarian cancer, especially if you have a personal or family history of these diseases. Prompt treatment and early detection can help improve outcomes.

Frequently Asked Questions
Aside from breast cancer, people with ovarian cancer might be at an increased risk for these other cancers:
- bladder cancer
- bile duct cancer
- colorectal cancer
- acute leukemia
- melanoma of the eye
Breast cancer can spread to the ovaries, although this is relatively uncommon, and it's more likely to occur in advanced breast cancer cases, especially those that are hormone receptor-positive or those with BRCA mutations.
Those at high risk of ovarian cancer include individuals with:
- 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
- age over 40 years
Summary
There's a strong connection between breast and ovarian cancer due to common genetic mutations, particularly in the BRCA1 and BRCA2 genes. If you've got these mutations, your risk of developing both cancers significantly increases.
A personal or family history of one cancer can raise your risk of the other. Understanding these risks can help with early detection and prevention strategies. If you suspect anything or need more information, don't hesitate to consult your healthcare provider.
- The connection between breast cancer and ovarian cancer is primarily based on shared genetic mutations, such as BRCA1 and BRCA2.
- Women who have been diagnosed with breast cancer might face a higher risk of developing ovarian cancer later in life.
- Conversely, ovarian cancer patients may also have an increased risk of subsequent breast cancer, but the risk varies depending on the initial diagnosis timing.
- Other risk factors for both breast and ovarian cancers include a family history of either of the cancers, increasing age, weight, reproductive history, and hormone therapy taken after menopause.
- By maintaining a healthy weight, regular exercise, limiting alcohol consumption, and discussing contraception options with a healthcare provider, individuals can potentially reduce their risks of breast and ovarian cancer.
- Regular checkups, including mammograms, breast MRI scans, pelvic exams, transvaginal ultrasounds, and CA-125 blood tests, along with genetic testing for BRCA1, BRCA2, and other relevant mutations, can aid in early detection and prevention of these cancers.
