I'm sure some know, not all. True what you're saying about oncologists. They want that paycheck. However, I have read that many doctors and oncologists if they or their family members get cancer, they do not take the chemo/radiation route - they know it doesn't work!! When people get these barbaric treatments then die short time later, they didn't die from cancer, but from the toxic treatments. This is a horrible crime against humanity, along with the bio-weapon shots inflicted on millions worldwide.
My husband & I detox daily to get rid of heavy metals. We're being poisoned by air (chem-trails), food, water and whatever else. We haven't taken any vaccines for over 30+ years. If your pediatrician will not test your child's blood for heavy metals, best thing to do is find a holistic doctor who will help you.
Here's link about Vaccines & Autism at Weston A. Price Foundation website. This is an excellent website providing a lot of information on nutrient dense traditional foods, and so much more.
