Surveillance of a cancer diagnosis can be made by observing foot nails

The new method developed by American medics manages to identify lung cancer as a leg nail. This unique discovery belongs to scientists at the University of San Diego. Researchers have found that nicotine can be diagnosed with lung cancer on the nails. Nails on the fingers grow more slowly than the fingers and nicotine accumulate on the cornea.  It is precisely due to the amount of nicotine that can determine the risk of developing lung cancer.
