Because you have a family history of breast cancer, you will likely need additional monitoring to insure that any lesions are found early and dealt with. In the case of a cough, it is very unlikely that it could be related to breast cancer. We do see patients with a cough associated with breast cancer that has metastasized to the lungs, but you would likely see other symptoms of metastatic disease (weight loss
, shortness of breath, perhaps a breast mass). Thus it is possible, but extremely unlikely that there is a connection between your cough and breast cancer. A chronic cough can have many different causes including asthma, smoking, and post-nasal drip. If your cough continues, you should be evaluated for asthma and post nasal drip since both are treatable conditions. If you are taking a drug for blood pressure known as an ACE inhibitor (such as Lisinopril), then you should be switched to a different drug because it can cause a cough. I would schedule an appointment with your primary care physician
while you are having the cough to get it evaluated. I would also get a referral to a breast cancer geneticist
for evaluation. They can take a detailed look at your family history and define what your risk is and recommend a suitable screening plan. Good luck.
