I was actually amazed at how .U.N-painful the mamogram really was. I had my first one about a year ago and, honestly, I wonder why people complain about it!
Having watched my mother inlaw suffer from breast cancer treatments for the past 9 months, I can tell you that a mamogram saved her life! Without her annual mamo, she'd have never known she had cancer.
They are easy and take very little time. I can't see why anyone wouldn't do it.
