“…Some published studies have documented a positive relation between high socioeconomic status (SES) and breast cancer risk [10][11][12][13]. While overall there is an inverse association between SES and cancer risk and almost all cancer incidences, in particular of the lung, stomach, pharynx, esophagus, and cervical uteri, are higher when SES is lower [10,[13][14][15], a positive association was found for cancers of colon, prostate, breast, and skin melanoma [13,14]. For example, in an Italian study, women with lower educational levels were at lower risk of breast cancer, melanoma, and ovarian cancers but had a higher risk of stomach, liver, and cervical cancers [16].…”
