Slathering on Sunscreen Does Not Prevent Cancer
August 02, 2003
are unsure whether sunscreen prevents against melanoma, the
deadliest type of skin cancer that accounts for more than 75
percent of skin cancer deaths. They suggest that sunscreen may
prevent sunburn, but may fail to protect against cancer. Sunscreens
are designed to absorb energy from ultraviolet light, however
the energy may be transferred to the DNA in skin cells, which
could cause problems.
Some studies have even found a link between melanoma and
sunscreen use, though researchers suggest this may only show
that people who are easily sunburned, who are more likely
to get melanoma, are also more likely to use sunscreen.
Researchers still recommend using sunscreen as it does protect
against basal cell carcinoma, the most common skin cancer
that is usually easy to treat, and sunburn, and it slows the
wrinkling of aging skin.
