We know that exercise can help your heart, but there is new evidence that it can also help you beat cancer.
The University of North Carolina study of more than 1,000 breast cancer patients suggests that five year survival rates were higher among those who exercised. "Physical activity makes you feel better in general, it improves your day to day how you feel, so it would be really exciting to find out how that reduces your risk chances of dying," said Marilie Gammon, a breast cancer researcher.
Researchers say physical activity may influence breast cancer survival in the same way it affects the odds of developing breast cancer by boosting the immune system, while reducing hormones that feed tumors. The study is published in the Journal Cancer.
