• Recurrent infections, such as Reference pneumonia Opens New Window.
• Pericardial effusion, which is the buildup of fluid in the space between the heart and the sac around the heart (pericardium). This condition is not common with lung cancer.

The long-term outcome (prognosis) for lung cancer depends on how much the cancer has grown and spread.
