Signs & Symptoms
In many cases, symptoms do not appear until the cancer is quite advanced. However, by the time a tumor does cause changes within the lungs, the signs include:
- Difficulty breathing—stridor (a harsh sound with each breath), wheezing, labored breathing, shortness of breath (SOB);
- Coughing, possibly with blood in sputum;
- Recurring pneumonia or bronchitis;
- Chest, shoulder, or arm pain;
- Loss of appetite;
- Weight loss;
- Bone pain;
- Hoarseness;
- Headaches or seizures;
- Swelling of the face or neck;
- Fatigue.
Early Detection
There are no routine screening tests for lung cancer. Detection at an early stage is possible with an x-ray or sputum analysis and some doctors order these tests, especially for people who smoke. However, there is no evidence that such attempts at lung cancer screening have a positive impact on treatment or survival. If a doctor suspects lung cancer, an x-ray is the first step in diagnosis.
