Abstract: To explore the relationship between heavy metals exposure and breast cancer, 96 newly diagnosed cases of breast cancer (cancer group) and 30 matched normal cases (control group) were adopted as study materials, and the contents of heavy metals (Cd, Hg, As, Cr, Pb) in serum and breast tissues were determined by inductively coupled plasma mass spectrometry (ICP-MS). It was shown that Cd, Cr, As and Pb contents in serum and breast tissues in the cancer group were significantly (P<0.05) higher than those in the control group. Logistic regression analysis showed that Cd, Cr, As and Pb contents in the serum were associated with breast cancer risk. ORs of Cd, Cr, As and Pb were 12.364 (95%CI: 3.405-44.889), 132 (95%CI: 14.257-1 222.1), 4.941 (95%CI: 1.521-16.047) and 7.416 (95% CI: 0.326-9.980), respectively, indicating that exposure to environmental heavy metals such as Cd, Cr, As and Pb may be one of the risk factors for breast cancer.
