"Drugs used to block copper absorption for a rare genetic condition may find an additional use as a treatment for certain types of cancer, researchers at Duke Medicine report.
"The researchers found that cancers with a mutation in the BRAF gene require copper to promote tumor growth. These tumors include melanoma, the most dangerous form of skin cancer that kills an estimated 10,000 people in the United States a year, according to the National Cancer Institute...
"Already, a clinical trial has been approved at Duke to test the copper-reducing drugs in patients with melanoma, although enrollment has not yet begun."
Editor's note: The scientists hypothesize that copper-reducing drugs might help fight melanoma tumors with BRAF mutations, as detected by molecular testing.
