In my skin.

Rates of melanoma, the deadliest skin cancer, continue to climb, more than tripling in Caucasians between 1980 and 2002, according to the American Cancer Society. Now skin cancer experts at the University of Newcastle upon Tyne have developed a novel test that uses a small skin sample and responses to a ten-page questionnaire to produce highly personalized assessments of the risks individuals face from their sun exposure to date. Patients also receive personalized skin protection advice and can re-take the test to see how changes they've made have affected their skin cancer risk. The "skinphysical" test was launched at British clinics in the autumn of 2005.
