ABSTRACT
To measure the concentration of total antioxidant status [TAS] in women with breast cancer. This is a case control study conducted in Al-Salam Hospital and Department of Pharmacology in Mosul Medical College. Twenty women having histologically confirmed breast cancer and twenty age-matched healthy volunteer women participated in the study. Serum total antioxidant status [TAS] was measured in both groups. Mean TAS of the patient group [0.91 +/- 0.32 mmol/l] was significantly lower [P<0.001] than that of the control group [1.82 +/- 0.14 mmol/l]. The present study demonstrated that women with breast cancer have a low level of TAS as compared to those of healthy women. It further emphasizes the growing concern that oxidative damage may occur in those patients that exhaust the antioxidant defense of the body leading to a low levels of TAS. Administration of antioxidant supplements such as a combination of vitamins A, C and E are necessary in women at high risk of developing breast cancer or after surgery or with anticancer drugs
