@engineer,
I'm slow on the pink ribbon stuff at the same time I'm glad I knew to get my mammos. We talked about this on a recent thread because Butrflynet and Bumblebeeboogie left a dozen pink roses at my door one day, not long ago - and I liked getting them.
I'm aware of at least reported stuff about questions re reactivity on early breast cancer or prostate cancer being problematic - there has been talk of this for many years now. I have further comments - my xray showed calcifications that an immediate ultrasound scored as worth looking at, and they turned out to be invasive. A lot of the recent talk is to cut down chasing calcifications.
On prostate cancer, I see a lot of information - do you not get google news?
My own bias is against organized campaigns. Me, if I had millions, I donate some to specific research facilities.
