Pia, I understand how it felt to lost a friend. I almost lost mine too.
From your story, it seem that your friend did not really follow Clark protocol.
Chemo, Radiation, Surgery, and Clark protocol don't mix as stated in her book.
When come to advance cancer, no one would want to follow alternative until its too late. Especially cancer, mainstream doctor will scare the hell out of the patient and their families.
The main tactic is, if you don't do surgery, chemo, radiation thread, even though they know that it didn't really work. I have friend who gone cutting off arms, leg, a certain organ remove, eyes and so on. They look so deform after their doctor visit. Dr. don't give a damn how deform it as long they got the $$$. They even add, as long you can still live statement.
PS. Don't be afraid to go off orthodox completely.
