Fact or Myth: Deodorant Causes Cancer

The idea that aluminum in deodorants causes cancer is not strongly supported by science. Many studies have looked into this, and reputable organizations like the American Cancer Society and the National Cancer Institute say there’s no clear evidence for it. Aluminum is used in deodorants to stop sweat, but only a tiny bit might get into your body, and it’s quickly removed. While some studies have hinted at a possible link between aluminum and breast cancer, nothing has been proven and the largest studies on the topic have shown no link. So, it’s best to be cautious about believing claims that aluminum in deodorants leads to cancer. In tissue samples that have been studied, breast tissue from people who used aluminum antiperspirants did not contain more aluminum than from those who did not. In fact, the amount of aluminum absorbed from eating food each day is far greater than that absorbed from aluminum antiperspirant. 

While this is good news in general, during some cancer treatments your doctor may need you to avoid antiperspirant, as well as many other skincare products. They should let you know and should be able to provide alternative options if you ask.
