Ultra-Violet Light and Skin Cancer
G. M. Findlay O.B.E., M.D., Sc.D.
1. By exposure of mice to ultra-violet light for a period of not less than eight months it is possible to produce papillomata and malignant epitheliomata of the skin.
2. When mice are tarred and exposed to ultra-violet light at the same time, the period necessary for the induction of cancer is shorter than when either tar or ultra-violet light alone is employed.
3. A series of mice tarred for one month failed to develop cancer, but when tarred and exposed to ultra-violet light for the same period three mice developed malignant growths.
