Get a 2nd opinion quickly because lung cancers are treatable when found early (usually before symptoms). Do you smoke? You don't mention why you were having a chest X-ray. A non smoker can get a different type of lung cancer that responds well to treatment. But you can only diagnose ca through a biopsy.
In the past, tuberculosis was sometimes mistaken for cancer on x ray, but in this day and age we have other methods of confirming the diagnosis.
I am a woman, 58 years old, from Germany. In addition to lung cancer, I have big problems and pain, because my pancreas pushes out my gall and I therefore already had about 20 ERCP procedures (endoscopic retrograde cholangiopancreatography pancreaticography).
