Lung cancer usually has no symptoms in its early stages. When signs of the disease start to appear, they can include:
- Chronic, hacking, raspy coughing, sometimes with mucusthat has blood in it
- Changes in a coughthat you’ve had for a long time
- Respiratory infections that keep coming back, including bronchitisor pneumonia
- Shortness of breath that gets worse
- Wheezing
- Lasting chest pain
- Hoarseness
- Swelling of the neck and face
- Painand weakness in the shoulder, arm, or hand
- Fatigue, weakness, loss of weightand appetite, fever that comes and goes, severe headaches, and body pain
- Trouble swallowing
These problems usually happen because of blocked breathing passages or because the cancer has spread farther into the lung, nearby areas, or other parts of the body.
