Glen you should really go spend some time by going to an oncologist with someone, actually with someone you love. Then go with them through treatment, surgery, chemo and radiation. Not only to support your loved one but to see others in each place doing the same thing. Success story right here in our household.
Then we have the ones I know relatives included that think it isn't real and denial, denial, denial thinking like you seem to do. It can't happen to me so consumed with addiction until it's too late. Then we watched until they are consumed with cancer. All that time it wasn't by my tobacco use it was because of something else that everyone blamed it on.
Are you saying everyone dying of cancer or being it's imaginary they should just give up and not fight?
