This was really interesting...a cancer patient (not ovarian) who died, researchers were allowed to explore her genome (the first time for a cancer) and explore how it worked against health tissue. They were surprised and admitted this proves how little we all know about cancer.

The one piece I took from the article is that with faster DNA sequencing, this can proablly be done on other cancers like ovarian...we can only hope (speaking of, the NCI *did* choose ovarian as one of three, I believe, cancer they will be exploring in depth via genome)
