You should not have to wait a year for a mammo if there is a problem or area to investigate. Please see your doctor and ak for the referrals you need to gt to the bottom of it. Routine or screening mammograms are done annually but if there is any need for any other mammo during the year, they call it a diagnostic mammogram and it gets coded differently. Check with your insurance to be sure but don't put off an exam just for the insurance. It's probably nothing, but best to be sure.
