Training in the sun

From the New York Times on November 21 ..

``Marathon runners may have an increased risk for skin cancer, a small study published Monday suggests, and excessive sun exposure and exercise-induced suppression of the body’s immune system may be involved.
The lead author of the report, Dr. Christina M. Ambros-Rudolph, said the pilot study had reached no conclusion about the exact increase in risk that marathoners face.

But, Dr. Ambros-Rudolph said, “Our results show that there is a difference, in particular in sun exposure and measurable consequences such as increased solar lentigines.”

Solar lentigines are “age spots” caused by long-term sun exposure.''
