I am so sorry to read about your sister (in one of your other posts). Is it for her that you are researching on this site? It's great that you are so supportive of her - if only everyone who got cancer was so lucky!
Mum started taking wobenzym immediately upon diagnosis on the recommendation of a family member who is a surgeon in the Czech Republic. I don't know too much about it, but the following link might be of some interest

Please share anything that you have come across in your travels that might be of value to us!!
Welcome to our group.
