THE AETIOLOGICAL POSITION OF SUNLIGHT IN SKIN CANCER.

This article focuses on the paper "The Aetiological Position of Sunlight in Skin Cancer," by H. Gratmann and E.-M. Reiners. This is an analysis of 24-73 cases of skin cancer. The authors found that epithelioma was commoner in rural male patients than urban ones. Epithelioma of the lower lip was commoner in rural patients and those urban ones more exposed to sunlight, than in town dwellers with indoor occupations. They consider that these types of skin cancer may have to be accepted as occupational diseases. There is no significant difference in basal-celled tumors and in the female.
