Analysis of the Relationship between Climatic Elements and Skin Cancer in Ardabil Province

The purpose of this study was to investigate the relationship between climate change and skin cancer in Ardabil province. Multiple regression equations were used to analyze the relationship between climatic variables (frost, sunshine hours, mean humidity, maximum absolute temperature, minimum absolute temperature and average temperature) with changes in skin cancer at the stations. To determine the independent variables affecting skin cancer changes in the studied stations, a backward regression model was used. The results of this study showed that the correlation between climate variables and skin cancer in the studied stations is relatively significant and these correlations are often strong and significant at 0.01level with each other. The direct correlation between skin cancer and other climatic variables in the studied stations showed that the incidence of skin cancer in the warmer half of the year was more than the cold half of the year. Quantitative correlation coefficient and percentage of changes explained by backward model to justify the number of skin cancer incidence in the studied stations under the conditions of entry of all climatic variables and also in the case of removal of some low climate variables (entry of high-impact climatic variables ) showed that in the studied stations, the entry of all climatic variables in determination the amount of skin cancer incidence, between 79 and 91, and the withdrawal of single or multiple variables, and the remaining variables in backward regression model, range from 76 to 89 percent of these changes are explained.
