Copper for treatment of Wilson's disease have been investigated for use in cancer therapy. Copper is an essential trace element in plants and animals, but not all microorganisms. The human body contains copper at a level of about 1.4 to 2.1 mg per kg of body mass. Copper is absorbed in the gut, then transported to the liver bound to albumin.

Ceruloplasmin also carries the copper that is excreted in milk, and is particularly
