My dad has pc with mets to the bones. he has done vitaminc c iv for a while and stopped but will start back up this month... for - he has an agressive pc and the vitamin c in super high doses did not seem to work for him in the Chemo type way we expected.. BUT it seemed to slow things down and he felt so much better with so much more energy! Along with all the supplements and diet he is on is what is keeping him going! So it is definitly worth a try and even if it does not cure hi it is making his body strong!!
