The results revealed that the distribution of EGFR gene mutation types in the lung cancer patients of the coal-producing areas and the non-coal-producing was statistically significantly different (p = 0.005), whereas the diversity of EGFR gene mutation types in the coal-producing areas lung cancer patients was significantly more than that of the non-coal-producing lung cancer patients (Fig. 2). This evidence concerns the gene EGFR and lung cancer.
