Why is lung cancer often found at a later stage when people first notice symptoms?
Lung cancer often does not cause symptoms at first. It may not cause signs until it is advanced. This is one reason it is often found later.
Lung cancer is often found at a later stage because it frequently causes no symptoms at first. Lung cancer may not cause any signs or symptoms until the cancer is advanced. Because of this, it is sometimes found by chance, such as during a chest x-ray done for another health problem. Confirming lung cancer also takes more than just a scan. A doctor reviews a person's health history and family history, and does a physical exam. The care team may also order imaging tests, like a chest x-ray or CT scan, plus blood tests. They may take a small tissue sample, called a biopsy, to look closely at the cells. Going through all these steps takes time, which can add to a later diagnosis. Your care team will tell you what signs and symptoms to watch for. If you have any concerns, it helps to talk with your care team.
