NEW YORK, June 18: Watching and routinely examining men with early, slow-growing prostate cancer is more effective and cheaper than sending them to surgery or radiation right away, according to a new study. The findings are based on a model of 65- to 75-year-old men that takes into account costs of tests, treatment and missed work, treatment side effects, men’s quality of life and their chance of dying from prostate cancer.
