Lung cancer: Symptoms and treatment

Lung cancer is a type of cancer that begins in the lungs. Your lungs are two spongy organs in your chest that take in oxygen when you inhale and release carbon dioxide when you exhale


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 mucus that has blood in it
  • Changes in a cough that you’ve had for a long time
  • Respiratory infections that keep coming back, including bronchitis or pneumonia
  • Shortness of breath that gets worse
  • Wheezing
  • Lasting chest pain
  • Hoarseness
  • Swelling of the neck and face
  • Pain and weakness in the shoulder, arm, or hand
  • Fatigue, weakness, loss of weight and 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.
