I wear pink for everybody - for those who have had breast cancer, for those who have it, for those who will have it in the future, even for those who don't have it, because there is a big chance that somebody who they know and care for has it, too.
Fortunately, nobody that I can recall in my closer circles has had breast cancer. But my life hasn't been unaffected by cancer in general, and I have lost sombody close to me of it before not to mention that I have known others who have had it.
It never hurt anybody to give and receive a little more love and hope and I would like to share mine with everybody. Nobody is unaffected by cancer.
