How can it be diagnosed?
The symptoms of lung cancer usually appear only with advanced disease. If your doctor finds something suspicious in screening or you have any of the symptoms of lung cancer, further tests will be required to diagnose the condition.
If you have one or more symptoms indicative of lung cancer, you should visit your doctor, who will examine you and ask for relevant tests.
Medical history and physical exam: If your doctor suspects you might have lung cancer, he will ask you about the presence of risk factors like smoking, your occupation, etc. He will also examine you for signs of lung cancer and other health problems.
Depending upon the findings, the doctor might advise certain tests.
