LONDON - Louise Butcher hopes that when she becomes the first woman to run the London Marathon topless on April 21, having had a double mastectomy in 2022, the thousands of supporters lining the course see a powerful image of strength.

The 50-year-old breast cancer survivor runs topless to help erase the stigma around the disease -- and there are few bigger platforms, she said, than one of the world's biggest road races.
