History of exercise helps prevent heart disease after breast cancer

A study found that women with breast cancer who engaged in regular exercise were 40% less likely to have a cardiovascular event and 60% less likely to die from coronary heart disease. Exercise may help mitigate the increased cardiovascular risk faced by cancer patients, reducing the risk of heart disease and its associated complications.
