The study looked at test results from 1976 to 2008. The article makes two 'helpful' points:
- mammograms do not help find late stage breast cancers any sooner so the death rate from them has not gone down by much
- Between 70,000 and 80,000 women are treated annual for breast cancers that would never kill them
In my mind, that is the real target. Finding ways to determine if a cancer is deadly or a cancerous tumor that is slow growing or will be reabsorbed by the body. That would be a whole new focus of research.
