Thanks to the folks above that mention Mrs. Edwards. I didn't mean to forget to add the same thoughts and comments about her and her fight against cancer.
As noted by Dr. Guy, cancer may not seem to have a mind or intent, but the results are still devastating. When a body has cancer and that cancer starts spreading to various organs, it's normally a short period of time before the individual is dead, either from the treatment (which must be agressive to stop the spread of the cancer cells) and the reaction to it, or from the destruction of the cancer cells.
I hope that both of these individuals, and for that matter anyone fighting cancer, is able to win their own battles and eradicate their cancer so they can go on to a long(er) and health(ier) life.
