Have you heard the rumor about antiperspirants or deodorants causing breast cancer? Texas A&M AgriLife Extension Service and the Cancer Prevention and Research Institute of Texas would like to put your mind at ease regarding this false claim – antiperspirants do NOT cause breast cancer.
Researchers from both the National Cancer Institute (NCI) and the U.S. Food and Drug Administration (FDA) say “there is no conclusive evidence linking the use of underarm antiperspirants or deodorants and the subsequent development of breast cancer.”
You might also wonder why doctors tell women not to use antiperspirant or deodorant on the day of a mammogram. The American Cancer Society says the reason for this request is that “many of these products contain aluminum, which is a metal and can show up on a mammogram as tiny specks in the area.” These specks can look like a possible sign of cancer on the mammogram film. By avoiding the use of these products, you can help prevent any confusion when the radiologist looks at the mammogram films. Possibly this is how the rumors got started that the aluminum in deodorant causes breast cancer.
If you are concerned about breast cancer, talk with your doctor, nurse, or healthcare provider about your risk. You can also reduce your risk of developing or dying from breast cancer by avoiding or limiting the use of hormone replacement therapies, maintaining a healthy weight, exercising regularly, avoiding excessive alcohol consumption, and getting regular mammograms and clinical breast exams.
