I've quit giving to the Cancer Society
Amen. It breaks my heart when I see so many well-intentioned people getting involved with "Race for the Cure" or other cancer fund-raisers du jour...it is just money down a rat hole. (See United Way and Red Cross.) There is too much money wrapped up in cancer for anybody to waste time finding a cure. You are much better off watching what you eat and drink than you are donating for the 'cause'.
Isn't cancer related to the immune system? When David, the bubble boy, came out of his bubble malignant tumors popped up all over him--best I remember.
