30-Minute Daily Walk May Lower Breast Cancer Risk in Younger Women, Study Finds
A small Latvian study of 18 healthy premenopausal women (~41 years old) found that just 30 minutes of low‑intensity walking triggered changes in blood that increase anti‑cancer activity (myokines) and slowed the proliferation of HER2‑positive breast cancer cells; exercising 30–45 minutes at a moderate-to-high intensity produced stronger effects. Presented at the European Breast Cancer Conference, the findings align with public‑health guidance that regular activity may help prevent cancer, but researchers caution the results are preliminary and require further study.
