Lung Cancer

Common Questions & Answers
Symptoms of lung cancer include a persistent cough, coughing up blood, shortness of breath, chest pain, hoarseness, and losing weight without trying to.
It is recommended that people age 50 to 80 who have smoked the equivalent of one pack of cigarettes a day for at least two decades get a low-dose computed tomography (CT) scan every year, whether they still smoke or have stopped.
Lung cancer can spread, or metastasize, to the brain, bones, and liver. Lung cancer that has spread is called metastatic lung cancer.
