Canadian study of 32,000 toenails aims to shed light on prostate cancer
HALIFAX — They may be unappealing to some and not an obvious source of scientific data, but researchers are hoping a record-setting collection of 32,000 toenails will shed light on the most common form of cancer in Canadian men.
Scientists in the Maritimes and B.C. are examining toenail clippings from about 150 men with prostate cancer and comparing them to the nails of men without the disease.
“We’re going to use toenail samples as an indicator of risk factors specifically related to environmental exposure to heavy metals in development of prostate cancer,” Dr. Jong Sung Kim of Dalhousie University in Halifax told Global News.
He said they’re trying to detect cadmium and arsenic, since nails are said to be good biological materials to examine them in.
