I wish the word cancer was dropped from the medical dictionary.
Lots of people get cancer, some have a severe form and die a long painful slow horrible death, others die very quickly in little pain and others make a full recovery.
The word is used as a catch all, might as well say someone is "ill" - means nothing.
I'm not really sure what your trying to say? As a cancer survivor I can tell you that for those lucky enough to, in your opinion, "make a full recovery" the scars heal and the cancer is gone but the fear of return and the pain of what was the darkest, most uncertain time of my life will never leave. The word Cancer does not mean "nothing". Not for those who survived it, not to someone fighting it and not to those who have lost someone to it.
I wish JK all the best, he has no doubt come through this stronger than he could have imagined.
Isn't science awesome!
