Abstract
Breast cancer is the most common cancer diagnosed and the second leading cause of cancer death among Iraqi women. The population was exposed to high levels of depleted uranium following the first and second Gulf Wars and this might be a risk factor. Protein 53 (p53) or Tumor protein 53 (Tp53) was originally defined as an oncogenic protein. The aim of the study was to evaluate P-53 serum concentrations in fifty Iraqi female breast cancer patients and twenty five healthy volunteers using the ELISA technique. All these patients attended the Teaching Hospital of AL Diwaniyah during the period between June 2016 to March 2017. The mean values for TP53 concentration in patients with breast cancer and apparently healthy groups were 47+33.5 U/ml and 27. 8+12.7 U/ml, respectively. The results showed no significantly difference , in contrast to most studies conducted elsewhere in the world.
