It is my opinion that everyone has cancer in one form or another.
The key is to eliminate it before it gets out of hand.
As far as this cancer-detecting bra is concerned, that would be great, however, a 90% correct detection means that one of every 10 women would show a false positive, which would mean a doctors visit, which would mean they are now in the clutches of mainstream medicine, and that is not a good place to be, considering most doctors still think a yearly mammogram for over 40 year old women is a good idea, even though its been proven that over 2000 women would have to be screened every year for 11 years in order to save one life.
That would even be ok except for the fact that several of these women will get cancer from the constant ionized radiation, and many will die as a result. And that isn't even counting the 700 - 800 women who will show false positive, and all the crap that comes with it.
Cancer comes in two main forms. Its either man made, caused by pesticides, chemicals, ionized radiation, and poisons in air, food, or water... or the cancer is the result of being deficient in one or more of the 90 essential nutrients for an undetermined length of time.
Cancer will continue to rise in spite of doctors and treatments, and will kill even more of the population, no matter how much money is donated to cancer, because this is dead money and cancer has become a big black whole of a money pit. These organizations thrive on sickness, not on health.
