Deodorant and Cancer

Dear Dr. Bone,

I read that underarm deodorant can cause breast cancer. Is this true?

Dear Sweaty,

I remember getting an email many years ago about the hazards of deodorant. Actually, it was about antiperspirants, not deodorants.  What is the difference? Deodorants prevent or control odor related to perspiration, whereas antiperspirants work to prevent perspiration in the first place. A major concern about antiperspirants surrounded the aluminum content found in these products. Aluminum was thought to be linked to Alzheimer’s disease. The relationship between aluminum and breast cancer came later and still is hotly debated. Aluminum deposits are found in greater concentration in the areas of the breast where most cancers are diagnosed, and aluminum, like cadmium, has estrogenic-like activity on breast cancer cells.  A further risk involves the ingredients called parabens, which are used throughout the cosmetic industry. When absorbed through the skin sometimes from underarm shaving cuts, these parabens might conceivably accumulate in the fat cells of the breast or in the lymph nodes near the breast.

Despite these associations, there is no definitive study proving that deodorant or antiperspirants cause cancer. However, it makes sense that you should avoid unnecessary exposures that might be related to cancer, even if remotely. I advocate using only deodorants, not antiperspirants. Sweating is a natural mechanism to help us rid our bodies of toxins. Instead of trying to prevent sweating, I prefer to use a deodorant that eliminates odor naturally. The crystals in Naturally Fresh Deodorant products are pure, aluminum-free and paraben-free, and are hypoallergenic.  They are perfect for people working to prevent cancer, for cancer patients, and for cancer survivors.

And, in addition to their original fragrance-free line, Naturally Fresh now has lovely scented products, including lavender, papaya fusion, ocean breeze, and tropical breeze to appeal to men and women everywhere.
