My father was diagnosed with squamous cell
cancer in his lungs 2 years ago
and my grandmother on mothers side died from lung cancer also. This really bothers me. I have been on 4 rounds of different antobiotics, nasal sprays,mucinex dm, xyzal,delsem, robitussin, prednezone and I also take protonix for gerd. Nothing seems to work I am 37 years old and for the most part have been healthy. I had a chest X-ray last May 07. showed nothing then. Should I be worried.
