Evaluation of Selenium, Calcium and Membrane Potential among Breast Cancer Patients in Owerri

Background: Breast cancer is the cancer diagnosed in women mostly. Aim: This study was investigated to evaluate the level of selenium, calcium and membrane potential among breast cancer patients in Owerri. Material and Method: 38 breast cancer patients and 36 apparently healthy subjects between the ages of 45- 60 years admitted to General Hospital Owerri were selected in this study. Fasting venous blood was collected and was used for the determination of selenium, calcium and membrane potential. Results: The results obtained revealed that the levels of selenium and membrane potential were significantly decreased in breast cancer patients when compared with the control at P<0.05. Conclusion: This could probably imply reduction of selenium and cell membrane potential leading to oxidative stress.
