Can individuals in high-risk groups for breast cancer take oral contraceptives?


Hello, two women in my family have been diagnosed with breast cancer: my mother (with ductal carcinoma in situ) and my aunt (my grandmother's sister, stage II).
Am I suitable for taking oral contraceptives? Can I use any brand available on the market? If I take them, will it increase my risk of developing breast cancer? I would appreciate your assistance, thank you.

Qianxia, 30~39 year old female. Ask Date: 2022/11/30

Dr. Lin Xinwang reply Obstetrics and Gynecology


Hello Qianxia: Emergency contraceptive pills do not trigger breast cancer.
If there is a family history of breast cancer, you are considered high risk and it is recommended to undergo regular breast examinations.
The preferred choice of contraceptive pills is low-dose options.

When considering the use of birth control pills for women with a family history of breast cancer, it is essential to weigh the benefits and risks carefully. Given your family history, including your mother with ductal carcinoma in situ (DCIS) and your aunt with stage II breast cancer, it is understandable to have concerns about the potential implications of hormonal contraceptives on breast cancer risk.

Current medical guidelines suggest that women with a family history of breast cancer should have a thorough discussion with their healthcare provider before starting any hormonal contraceptive method, including birth control pills. The concern arises from the fact that certain hormonal contraceptives can influence estrogen levels in the body, and estrogen is known to play a role in the development of some breast cancers. However, the relationship between birth control pills and breast cancer risk is complex and not fully understood.

Research indicates that while there may be a slight increase in breast cancer risk associated with the use of combined oral contraceptives, this risk is generally considered low, especially for younger women. The risk appears to diminish after discontinuation of the pills. For women with a strong family history of breast cancer, the decision to use hormonal contraceptives should be made on an individual basis, taking into account personal health history, age, and the specific type of breast cancer in the family.

In terms of specific brands of birth control pills, there is no blanket restriction on which brands can be used based solely on family history. However, some formulations may contain higher doses of estrogen, which could be a concern for women at increased risk. Therefore, it is crucial to discuss with your healthcare provider the best options for you, which may include low-dose estrogen pills or non-hormonal contraceptive methods.

Additionally, regular screening and monitoring are vital for women with a family history of breast cancer. This includes self-breast examinations, clinical breast exams, and mammograms as recommended by your healthcare provider. Genetic counseling may also be beneficial if there is a significant family history of breast cancer, as it can provide insights into your risk and inform your healthcare decisions.

In summary, while women with a family history of breast cancer can consider using birth control pills, it is essential to have a detailed discussion with a healthcare provider to evaluate the risks and benefits specific to your situation. They can help you navigate your options and ensure that you make an informed decision that aligns with your health needs and family history.
