Our mobile mammography coach offers only screening mammograms (routine, annual exams for people with no current breast problems). If you are under the age of 40, you need a prescription from your physician for a screening mammogram. If you are over the age of 40, no prescription is required. If you currently have concerns regarding your breast health (e.g., a lump you can feel, nipple discharge, pain, dimpling of the breast or nipple changes), please contact your physician immediately.
