A new study by the Netherlands Cancer Institute shows that breast cancer patients who adhere to a physical exercise regimen through their chemotherapy suffer from fewer side effects like fatigue, physical disability, nausea and pain. Writing in the Journal of Clinical Oncology, the researchers said that even small amounts of low intensity exercise are beneficial compared to a sedentary life during chemotherapy. Nothing works as well as moderate intensity strength and aerobic exercise according to the study involving 230 women who were put through a moderate intensity exercise programme. These women endured chemotherapy the best with only 12 per cent of them requiring a dose adjustment. In contrast, 34 per cent of the women in the non-active control group required dose readjustments.
