2 cents plus 2 cents plus 2 cents... We may never get terribly rich here but we are better off than we were without sharing what we have to offer...
The drawback with PET is that it is more expensive, and as I understand it, it has limits in showing smaller tumors.
The biggest problem with the CT is that because it is now available in more places and is cheaper, even though the dose of rads is higher with it, more doctors are ordering it simply because they can. Again, I don't think I can say this too often or too loudly, but no one is keeping track of your total rads exposure (which is cumulative).
The study that Tom posted that discussed the 25% of breast cancer patients who have had chemo and eventually are diagnosed with another cancer later down the road may very well be a reflection not just of the chemo but of the continuing exposure these patients get to radiation through such procedures as CT, x-rays, mammography, etc.
