Knee Arthritis May Be Sign of Early Lung Cancer

NEW YORK (Reuters Health) - Having isolated arthritis in one knee could be an early warning sign for lung cancer, Italian researchers suggest. "Knee monoarthritis as an early manifestation of lung cancer has never been described previously," Dr. Fabrizio Cantini, from the Hospital of Prato, told Reuters Health. He noted that the knee trouble in such cases appears very early, "with the consequent possibility of surgical removal of the cancer."
