A lung nodule, also known as a pulmonary nodule, is a small mass of dense tissue on the lung, according to the American Lung Association. Leo on Sunday said the nodule was discovered by doctors in "a very initial phase" and that it was "well localized."
"The doctors think it is opportune to intervene," the 71-year-old said.
