Different people have different symptoms for lung cancer. Some people don't have any symptoms at all. About 25% of people with lung cancer do not have symptoms from advanced cancer when their lung cancer is found. Lung cancer symptoms may include:

  • Shortness of breath.
  • Coughing that doesn't go away.
  • Wheezing.
  • Coughing up blood.
  • Chest pain.

Other changes that can sometimes occur with lung cancer may include repeated bouts of pneumonia, changes in the shape of the fingertips, and swollen or enlarged lymph nodes (glands) in the upper chest and lower neck.

These symptoms can happen with other illnesses, too. People with symptoms should talk to their doctor, especially if they smoke, but even if they don't. Doctors can help find the cause.
