let. to ed. re. recent article in NY Times -- "Why We Need Health Care Reform"

I read with great interest the recent editorial advocating health care reform by the government. It is certainly impressive to see is the President writing in the Times. One thing in that was especially notable was that in one paragraph the President calls for insurance companies to pay for mammography and colonoscopy and the following sentence points how this will reduce the incidence of breast and prostate cancer. I wonder exactly how these two things are connected and to what degree these sentences show about the type of health and medical advice that the President is getting.
