Addendum from the Mercola site

From Mercola:

As this article points out, this myth can be traced back to the two industries that benefit the most: the cancer industry and the sunscreen manufacturers. These two giant profit-makers tag-team efforts which keep the unsuspecting public in a trance.

Not only do sunscreens promote cancer by blocking your vitamin D production, they are also likely carcinogens all by themselves. A study in the April 2004 Journal of Chromatography found that there is significant penetration of all sunscreen agents they studied into the skin.

and a Mercola reader adds:

Philippa Darbre, an oncology expert at the university of Reading, in Edinburgh, England, is the lead researcher of the recent study. According to her study, the chemical form of paraben found in 18 of the 20 tumors tested showed that they came from something applied to the skin, the most likely candidates being deodorants, antiperspirants, creams, and/or body sprays.

In an interview with the New Scientist [January 12, 2004], Darbre pointed out that:

"One would expect tumors to occur evenly, with 20 percent arising in each of the five areas of the breast. But these results help explain why up to 60 percent of all breast tumors are found in just one-fifth of the breast, the upper-outer quadrant, nearest the underarm."

The National Institute of Occupational Safety and Health has reported that nearly 900 of the chemicals used in cosmetics are toxic. Other groups believe the figure is much greater than that."
