Can Your Sunscreen Give You Cancer?

Sunscreens prevent sunburns, but beyond that simple fact surprisingly little is known about the safety and efficacy of these ubiquitous creams and sprays. 

FDA’s failure to finalize its 1978 sunscreen safety standards both epitomizes and perpetuates this state of confusion. 

EWG’s review of the latest research unearthed troubling facts that might tempt you to give up on sunscreens altogether. That’s not the right answer – despite the unknowns about their efficacy, public health agencies still recommend using sunscreens, just not as your first line of defense against the sun.

There’s no consensus on whether sunscreens prevent skin cancer.

The Food and Drug Administration’s 2007 draft sunscreen safety regulations say: “FDA is not aware of data demonstrating that sunscreen use alone helps prevent skin cancer” (FDA 2007). The International Agency for Research on Cancer agrees. IARC recommends clothing, hats and shade as primary barriers to UV radiation and writes that “sunscreens should not be the first choice for skin cancer prevention and should not be used as the sole agent for protection against the sun” (IARC 2001a).
