See what you can find. As far as I know the problem lies more with the copper. When a cancerous tumor grows past a certain size (imillion cells?)
It has to form its own blood vessels to survive. This is called angiogenesis.
A number of proteins are involved in angiogenesis (Vascular Endothelial Growth Factor being a main one) and most of these pro-angiogenesis proteins use copper as a cofactor. A Dr Linda Vadhat is treating triple negative breast cancer with copper reduction with some interesting results. Of course I cant say that zinc cant spur cancer growth.
