I'm glad they researched it. My wife's breasts had lumps, and she was always a little paranoid about them. She even had a couple of biopsies. Never missed her mammograms and even had the advanced 3D mammogram ones for dense breasts. Still wound up with Stage 3 Lobular Breast cancer. The first symptom was that her breast suddenly swelled up to double in size--no lumps whatsoever. The cancer was completely invisible on mammogram. It took an MRI to see it. Between causing anxiety over benign things and 15% of breast cancers that are even invisible on a mammogram, I'm quite unsurprised at the ineffectiveness of self-exams.
