Connection and Risk Factors Between Breast Cancer and Ovarian Cancer
Breast and ovarian cancers share a strong genetic link, particularly for individuals carrying mutations in the BRCA1 and BRCA2 genes. These genetic factors significantly increase the risk of developing both cancers.
Research reveals that people with a history of breast cancer may have an elevated risk of ovarian cancer. This increased risk is especially pronounced when breast cancer is linked to BRCA1 or BRCA2 mutations, although the risk is attributed to the underlying genetic factors rather than the disease itself. In fact, individuals with breast cancer are approximately twice as likely to develop subsequent primary ovarian cancer.
Reciprocally, those with ovarian cancer may also face an increased risk of breast cancer, though the risk varies with time since their initial diagnosis. People with ovarian cancer also show an elevated risk of developing breast cancer, which may be attributed to genetic mutations.
Apart from genetic factors, other shared risk factors include older age, overweight or obesity, and never carrying a pregnancy to term. Individuals may be able to mitigate some of these risks, such as achieving and maintaining a moderate weight.
BRCA1 and BRCA2 gene mutations are among the most significant shared risk factors for breast and ovarian cancers. Around 10-30% of families with these cancers carry BRCA1 gene mutations, while approximately 20% have BRCA2 mutations. Other shared risk factors may include a family history of either cancer, family history of colorectal cancer, Lynch syndrome, endometriosis, never having children, and not breastfeeding.
Some risk factors, such as having a history of breast or ovarian cancer, are unchangeable. However, managing these unchangeable risk factors may involve careful monitoring, lifestyle changes, and, in certain cases, preventive medical procedures. People carrying genetic mutations may consider additional measures such as prophylactic surgeries to prevent the occurrence or spread of cancer.
Modifiable risk factors, on the other hand, can be influenced. These include maintaining a moderate weight, regular exercise, limiting alcohol intake, and using oral contraceptives judiciously.
Individuals diagnosed with both primary breast cancer and primary ovarian cancer may have a relatively favorable outlook, with 5- and 10-year overall survival rates of around 90%. The outlook is generally more positive when the interval between the two diagnoses is longer. However, ovarian cancer following breast cancer often involves later-stage diagnosis, which can negatively affect survival.
In the event that signs or symptoms of breast or ovarian cancer appear, especially in individuals with a personal or family history of these diseases, it is essential to consult a medical professional. Regular screenings and prompt treatment are crucial for improving outcomes.

- Similarly, people with ovarian cancer may also be at an increased risk of developing breast cancer, a risk that may be attributable to genetic mutations.
- Age, overweight or obesity, and never carrying a pregnancy to term are shared risk factors aside from genetics for both breast and ovarian cancers.
- Managing these unchangeable risk factors may involve careful monitoring, lifestyle changes, and, in some cases, preventive medical procedures.
- People carrying genetic mutations may consider additional measures, such as prophylactic surgeries, to prevent the occurrence or spread of cancer.
- Modifiable risk factors, like maintaining a moderate weight, regular exercise, limiting alcohol intake, and using oral contraceptives judiciously, can help reduce the risk of developing breast or ovarian cancers.
- Managing mental health, skin care, nutrition, and weight management are all integral components of overall health and wellness, especially for individuals at a higher risk of cancer.
