The trace elements of the basic biologic components in the human body and animal, i.e., the increase and decrease in them cause a lot of damage such as toxicity. In this study, 25 samples of newly diagnosed breast cancer patients who did not receive any chemotherapy or radiotherapy were compared with 25 healthy females' volunteers. Level concentrations of serum of healthy and patients for each of the trace elements Ag, Pb and Cd were obtained by using atomic absorption spectrophotometry. There is not statistical significance found in serum levels when the mean concentration of patient and healthy females were compared, where the P-value is found (0.05 < p).The elements levels in patient serum might be important in pathogenesis of breast cancers.
