Debunking the myth: Breast cancer and antiperspirant use

Cancer News in Context:http://www.hsph.harvard.edu/cancer/

[October 30, 2002] Long the subject of Internet rumor, the

relationship between antiperspirant use and breast cancer was

recently put to the test. In a study published last week in the

Journal of the National Cancer Institute, researchers reported that

they found absolutely no connection between antiperspirant use and

breast cancer risk1. To avoid additional speculation, they also

looked at deodorant use and underarm shaving—and again saw no impact

on the risk of breast cancer.

Of course, the scientific community rarely accepts the results of a

single study as fact. However, in this case, researchers were

investigating a claim that had no factual basis, was not supported by

any type of research, and was inconsistent with everything known

about the development of breast cancer. Hopefully, the publication of

this study will finally dispel a myth that has caused a great deal of

concern and confusion.

Freed from this rumor, women can now put greater energy into the

behaviors that are known to help lower the risk of breast cancer:

maintaining a healthy weight, being physically active, limiting

alcohol intake, and breastfeeding (if possible). They should also

talk to their doctors about how birth control pills and

postmenopausal hormones might affect their risk. Finally, all women

should get regular screening tests for breast cancer, including

clinical breast exams and mammograms starting at age 40 (or earlier

if there are special risks or concerns).

Unfortunately, we will probably never be rid of health rumors like

the one that circulated about antiperspirants and breast cancer.

However, there are ways to help ensure the soundness of the health

information found on the Internet. One of the best ways is to start

searches at sites that are known to be reliable, like those of the

federal government, large health organizations, and established

medical and public health schools. Consumers can also get the truth

on health-related rumors by bookmarking " Hoaxes and Rumors " at the

Centers for Disease Control and Prevention website. By taking these

few extra steps, people can better decide which health information

should be acted on and which should be disregarded.
