Hi Cousins, Regarding Brease Exams and Xrays. I use to work for Xerox Medical Systems (a previous div of Xerox and no longer around) who produce a Xeroradiography machine used in early detection of breast cancer. Their guide lines for Xray exams was to have an Baseline (a Normal one to compare to later) in the 20's (earlier if breast cancer is in your family), then every 5 years until forty, then every 2 yrs until fifty, then every year thereafter. The risk of breast cancer increases significantly after fifty. Please, Kilgore men don't ignore yourself. Breast cancer does occur in men too. Take care, Barbara Rowe
