This article is a wake-up call for when you have any kind of medical test. What the author is saying is that when you have a biopsy, you are getting cut into your skin. Your skin is your protective barrier against disease & infection. The question now is: is did this cut for the biopsy let in bacteria or perhaps cancer cells from the outside of your body now into your body.?

The article furthur relates the worry that there are many unnecessary biopies being done because of false positives of other tests.

So what you want to do is to prevent false positives on tests by NOT USING skin care products that contain metals such as aluminum (deodorants) or parabens (in makeups & skin care products, soaps lotions) that can get absorbed into your breasts & armpits before you go for a breast MRI, mammography, etc.

If you can avoid having false positives on your tests by not using certain skin care products before them, you can avoid unnecessary biopsies.
