[Skin cancer incidence in Zacatecas].

Background: Skin cancer is the most frequent cancer related to ultraviolet radiation. The aim was to estimate the incidence of skin cancer type, melanoma and non-melanoma in Zacatecas, Mexico.

Methods: An epidemiological study was carried out during the period from 2008 to 2012.

Daily doses of biologically active UV radiation retrieved from commonly available parameters.

A multiple linear correlation is done between atmospheric transmissivity for four biologically active radiation daily doses (UVB, erythemal, DNA and plant damage) T, and three parameters (daily sunshine fraction sigma, cosine of the daily minimum solar zenith angle mu min and daily total ozone column omega). T is defined as the ratio of a daily dose to its extra-atmospheric value. The data used are spectral UV measurements (390-400 nm at 0.
