I found the NYTimes artical supports what I think about the biopsy technique used as the only way to classify the breast cancer. The overtreatment is another issue deserving more discussions.
I DO think the biopsy technique used as the standard breat cancer diagnosis tool is not accurate as you expected. Completely using the biopsy results to make your cancer treatment decision could either kill the innocent people or ignore the real cancer patients.
Thank you for your professional comments.
