Cancer and metal

Atomic absorption spectroscopic analysis of blood samples from cancer patients suggests that they have raised levels of a range of trace metals. Chemist Munir Shah of the Quaid-i-Azam University, in Islamabad, Pakistan, working with biochemists Qaisara Pasha and Salman Malik have focused on these qualities in an investigation of plasma trace metal concentrations in cancer patients and compared their findings with healthy controls. Whether or not this results from metabolic changes in the bodies of those with cancer or whether the presence of high levels of trace metals may itself by linked to carcinogenesis is not yet known.
