Running after cancer

Jamaican sprinter Novlene Williams-Mills was 30 and at the peak of her career when she discovered she had breast cancer. This was just before the 2012 London Olympics; she decided to compete anyway and won bronze in the 4x400m relay. Novlene describes what was going through her mind as she received that medal.
