A three-decade study has found that men who have advanced prostate cancer can gain up to an extra three years of life by having their prostates removed (versus those who are simply monitored during that period). The conclusion does not apply to men who are the early stages of the slow-moving, but life-threatening, cancer.
I wonder whether similar conclusions have been reached with respect to breast cancer and total mastectomies.
