Are you familiar with the work of Matthias Rath?

Hi Dr. V.,

I was just recently introduced to Matthias Rath and his work. He suggests that protease is one of the causes of cancer - I guess it might break down collagen and allow the cancer cells to migrate, or something like that. I remembered that there was protease in Vitalzym. Are they the same protease? I have taken a ton of Vitalzym. Thanks for any insight you may have into this area.
