Getting Hydrogen Peroxide Inside the Cancer Cells
Proteolytic enzymes (also called: pancreatic enzymes) literally cut apart the thick protein coating which covers cancer cells. Proteolytic enzymes are normally used to cut apart the protein coating so that the immune system can recognize the cells as cancerous. The use of proteolytic enzymes for this reason has been around for decades.
By cutting apart the protein coating proteolytic enzymes may also be able to get much more hydrogen peroxide inside the cancer cells.

I am taking serrapeptase for what you are referring to...
