 is very well evidenced that if you do a simple lumpectomy where you're taking out the cancer surrounding tissue but you leave most of the breast when you do that the survival is not any worse than taking it all out if you get radiation afterward. So basically you're out from getting the whole breast tissue and all the tissue removed is when you're doing radiation after a lumpectomy where you're taking out like a portion of the breast. So that's let me make that clear for everybody so if you think why are they only taking a little bit of breast cancer take the whole thing out that's why this study show the radiation does the trick.
