What are the warning signs of lung cancer?

ANSWER

If a routine physical exam reveals swollen lymph nodes above the collarbone, a mass in the abdomen, weak breathing, abnormal sounds in the lungs, dullness when the chest is tapped, abnormalities of the pupils, weakness or swollen veins in one of the arms, or even changes in the fingernails, a doctor may suspect a lung tumor. Some lung cancers produce abnormally high blood levels of certain hormones or substances, such as calcium.
