A routine screening mammogram can help detect cancer early, when it's most treatable. This video from MD Anderson demonstrates what you will experience when you have a mammogram. They recommend that women with an average risk begin annual mammograms at 40 years old.  I recommend that if it's time, get it scheduled, then treat yourself to something special when it's done. Even if it's just a drive-thru milk shake or a new bottle of nail polish, do something to pat yourself on the back when you're done.
