In the breast cancer significant differences occurs in the normal distribution of the trace elements, playing an important role in carcinogenic process. The aim of this study was to investigate the serum levels of some trace elements (Chromium, Cadmium, Manganese, Cobalt, Nickel, Selenium, Zinc, Iron, Copper and Magnesium) by using flame atomic absorption spectroscopy (FAAS). The present study included 150 females, the participates were divided into two main groups, control group which consisted of 75 apparently healthy females, 75patients with breast cancer group .The serum levels of Chromium (tcal2.9631 ,ttab1.960), Cadmium (tcal2.0798 ,ttab1.960), Manganese (tcal18.5676, ttab1.960), Selenium (tcal2.2759,ttab1.960), Iron (tcal2.9296,ttab1.960), Copper (tcal4.0869, ttab1.960),Magnesium (tcal2.6648, ttab1.960), Cobalt (tcal3.8615 , ttab1.960) and Zinc (tcal7.0160, ttab1.960) were statistically significant higher in the breast cancer patients group than the control group. Similarly, Nickel (tcal1.5988,ttab1.960) levels showed significant lower level in breast cancer patients group. On the other hand, the higher levels of trace elements could lead to formation of free radicals or other reactive oxygen species. The evaluation of these trace elements in serum maybe used as helpful tool in diagnosis of the breast cancer.
