Yes, you're quite correct. We have come a long way and over the past few years made further advancements. For instance, the Sentinel Node Biopsy. My cousin had all her lymph nodes removed some years ago, even though she was very young, in an abundance of caution. They can now detect cancer if it's there by putting blue dye into the 'first' or Sentinel Node at the same time as the cancer surgery. They send it to the Lab to be tested while the Breast surgery goes ahead. If there is no cancer in the Node, they know there is no cancer in the lymphatic system, and they don't remove anything there. It now seems such a simple solution. I had this particular biopsy done recently and thank God for all those medical personnel who made this happen.
