00:06:54 The long awaited results of a 10 year prostate cancer trial were published last week in the New England Journal of Medicine. The study looked at 1,643 men diagnosed with early prostate cancer, and found that those who actively monitored their cancer instead of immediately starting treatment had the same minuscule risk of death as men who had either radiation therapy or surgery straight away.
