The research shows that an-hour walking a day can cut women’s chance of breast cancer significantly, according to the study published in Cancer Epidemiology, Biomarkers and Prevention.
The team monitored the incidence of cancer in a group including over 73,000 women from 50 to 74 years-old who had been recruited by the research society between 1992 and 1993.
The result indicated that those women who walked for at least seven hours per week had a 14% lower risk of breast cancer compared to those ones who walked three or fewer hours.
“We were pleased to find that without any other recreational activity, just walking one hour a day was associated with a lower risk of breast cancer in these women,” said the study leader Dr Alpa Patel, a senior epidemiologist at the American Cancer Society in Atlanta Georgia.
The study once again highlights the significant role of lifestyle in influencing the risk of breast cancer, the chief executive of Breast Cancer Campaign Baroness Delyth Morgan stated.
The experts recommend people exercise at a moderate intensity for about 2.5 hours a week.
A similar study in men had earlier revealed that brisk walking for at least three hours a week could reduce the risk of progression in patients diagnosed with early-stage of prostate cancer.
Scientists believe exercising may prevent “recurrence through changing the blood levels of certain proteins involved in triggering or boosting cancer growth.”
