From Respectful Insolence:
No, Suzanne, what you said is not "controversial"; it's idiotic, ignorant, and disrespectful.
It was not chemotherapy that killed Swayze; it was his pancreatic cancer, a deadly disease. When Swayze was diagnosed, his cancer was stage IV, with metastases to the liver. The usual median survival of such tumors is less than six months. Swayze survived nearly 20 months. We can't say for sure that it was due to his chemotherapy, a less aggressive variety than usual of pancreatic cancer, or Swayze's top physical condition. It was probably a combination of the three that allowed him to live for so long.
What we can say from evidence is that "detoxing" and nutritional therapy does not work and, in fact, may even be more harmful. A regimen that sounds very much like the one you advocate, complete with colon cleanse "detoxing" and "nutritional" treatment was very recently shown to be far worse than chemotherapy and almost certainly no better than no treatment at all, which, as far as pancreatic cancer is concerned, is what it is. If Swayze had followed your moronic advice, chances are he would have died much sooner.
