Breast Self-Exams Good or Bad?

I was watching the news on TV the other day and their health news on breast self-examinations really confused me. I always believe that women who do breast self-exams are more likely to be saved from breast cancer for possibly detecting potentially cancerous lumps on their breast. Since I had a health scare last year after my mammogram, I always do breast self-exams. But there was a study made about breast self-exams that they may be causing more harm than good to women, that breast self-exams don't have cancer survival benefit for women. According to the study, breast self-exams could even hurt. There were women who do breast self-exams regularly and actually had more benign biopsies that are unnecessary and costly too, without finding any cancer anyway. And some of these women struggled with anxiety and fear that they might have breast cancer. Well in my opinion, women should always be attuned with their body changes, they should know how their breasts should feel like and look like. If you notice change and have unusual feel to your breast then you should see your doctor.
