I have had 2 mammograms and 2 breast ultrasounds. The ultrasounds were worse than the mammos.
My mom is currently battling Stage III breast cancer. She had surgery in June, she has been in chemo since July. In January she will start radiation. If she had gone for a mammogram on a regular basis her treatment would have been MUCH, MUCH easier. Her chances of surviving another 5 years would be MUCH, MUCH higher than 65%.
If the mammogram is a little uncomfortable, just think about the alternative and I bet you will feel better.
