When a patient, especially a smoker (even after stopping smoking cigarettes, the risk is still greater) has shortness of breath, or persistent and worsening cough, doctors always explore the possibility of lung cancer.
Common first symptoms of lung cancer are breathlessness and fatigue.
Lung x-ray can detect almost every cancer, but, not the smallest one that are easily caught at CT scan.
Blood vessels of possible lung cancer can be seen well on CT scan.
People with pneumonia may become short of breath, too.
Sometimes is hard to explain the shadow on chest x-ray, cause it can be due to many conditions.
Lung scarring can mimic pneumonia on x-ray, and pneumonia is sometimes difficult to distinguished from lung cancer on x-ray images.

CT scan is the most accurate test for lung diseases.

thanks for your reply, i am worried, as his mother died of lung cancer, can it be hereditary??

Having a parent or sibling with lung cancer doubles a person's risk of lung cancer.
