Hi there Meg,
Love and healing sent for Donald. Cancer is a terriffying battle for anyone to face, but there are a few things that he can do to help himself along a bit.
If he needs to have Chemo, the terrible side effects can be offset by taking Kelp suppliments. If you can find someone that can give him intravenous Vitamin C that will stop the side effects altogether. Your oncologist will not know this, he is only taught the main three "cures", chemo, radio therapy and surgery. One lady I know asked specifically for this and her consultant had never heard of it. Her GP HAD!!
One natural "cure" that has had no end of success stories to it's name is Essiac Tea.
You can get it from a number of places on the internet, but the Herbalist on the Ducking Stool (Alan Hopking) does a preperation that does not need boiling and straining. It's already done for you.
Phone him up and ask his advice - the number is 0500 909697
It may not work on ALL cancers, I don't know, but it has a reputation to recon with.
