The oxidative pathway and the alteration of the antioxidant defense have drawn attention to the pathophysiology of cervical cancer (CC). In our preliminary study, it was possible to corroborate the findings regarding the antioxidants of patients affected by CC. The total antioxidant activity and lipid peroxidation (LP) were evaluated in 14 people diagnosed with CC and 14 volunteers without CC (control group). Results showed low antioxidant activity in CC group. LP was not significant when analyzing CC group and control group. Our results indicate that changes in antioxidant defense may contribute to the pathophysiology of CC.
