It is true that breast cancer treatment has advanced greatly in the last hundred years. But survival of some types of breast cancer haven't changed much and the statistic in the graphic overstates the progress because you can't directly compare the cases found in 1920 with cases found now.
As well, all cancers are measured by 5 yr survival rates. A person can be clinging to life at 5yrs and die at 5 yrs + 1 day and still be counted in the survival rates. It’s a lie we’re fed. Living longer with cancer is not the same as being cancer free.
Also true, but of course you need some sort of standard for evaluating progress. That doesn't mean there aren't other ways to look at it.
Well said
