Also, the risk of mortality from cardiovascular diseases in these patients is more than other people. Aerobic exercise is effective in the prevention and treatment of cardiovascular diseases and breast cancer. This study was performed to investigate the effects of swimming exercise before and after of cancer on levels of Bax and Bcl-2 in female mice of myocardium. Materials and methods: In this study, 56 BALB/c mice were randomly divided into two active and passive groups. The active group swam in the water pool before breast cancer for four weeks, three days per week and 30 minutes daily. Passive group did no exercise before cancer cell inoculation. Then, both groups were separately divided into four subgroups: a) continue to exercise, b) rest, c) doxorubicin, and d) exercise/doxorubicin. Finally, Bax and Bcl-2 levels (as apoptotic markers) in myocardial tissue were measured. Results: The Results showed that level of Bcl-2 and Bax in myocardial tissue respectively increased and decreased significantly in the group that had aerobic swimming exercise before and after breast cancer in comparison to the group that did not exercise, . Conclusion: Aerobic swimming exercises before and after the breast cancer is effective on the level of Bax and Bcl-2 in myocardial tissue in mice with breast cancer. Therefore, regular swimming aerobic exercise may increase myocardial cell survival in breast cancer patients.
