The most interesting and hopeful thing I've heard of lately (maybe I heard it here on the Cellar) is the doctors who had discovered how to
culture cancer cells from a person with cancer.
The hope is that once this technique becomes perfected and widely available, they can get a sample from a tumor, grow more of it, so there are a hundred petri dishes full of this cancer, and then apply various chemo to the different dishes to see which kind of chemo is most effective for that particular tumor. Then the jump straight to that particular chemo, rather than just guessing and wasting time.
You read about these studies and the reporters all make it sound like its a huge breakthrough that will change everything, but they use words like "may," and "could," "promising," and "hope" but I was really encouraged when I read this news because it seems like a whole new approach. I hope it's implemented widely soon.
