Lung cancer can start in the windpipe (trachea), the main airway (bronchus) or the lung tissue. Find out about symptoms, risk factors and causes of lung cancer, diagnostic tests, treatment, including surgery, chemotherapy, radiotherapy and biological therapy, likely outcome (prognosis), research and how to cope with lung cancer, including managing breathlessness.
If you have cancer that has spread to your lungs from somewhere else, this is not the right section for you. We have information on secondary lung cancer that will be more suitable.
