We’ve known that physical activity can reduce breast cancer risk, and appears to work especially well at preventing estrogen-receptor negative tumors, the hardest ones to treat. But only last year did we figure how much exercise was needed. We’ve known that light exercise doesn’t work, like a leisurely stroll. It appears useless for preventing breast cancer. And we’ve known that fewer than 10 minutes a day of even good exercise doesn’t work either.
