Tinus Smits' carcinosin comes from one lab--Dolisos Netherlands, I think. He's a stickler for that particular remedy because it fits better with his own philosophical approach--that we have universal "layers" which have to be addressed with "more universal" remedies. Hence he doesn't use lac humanum, for example; he'll use lac maternum (source from several nursing women, not just one).

He also uses a remedy called carcinosinum-cum cuprum, which should address the way the body stores and uses copper, and how this metal functions in tumour formation and growth.

It is a kind of chemical/function approach to cure.

I think there are many different types of carcinosinum remedies; in the past there used to be different cancer tissues made into carcinosin remedies, so that not all "carcinosin" remedies were made with breast tissue. Carc. co. may be one of those "specific cancer tissue" remedies.
