lung mets

Had my leg amputated because of aggressive osteosarcoma 2 years ago.......now have a 7mm lung nodule that has gone from 6mm to 7mm in 2 years.  It is noncalcified and now am being sent to lung surgeon.   I am scared to death that this is it for me.  Has any one else out there had this kind of lung nodule  and what does it mean for osteosarcoma that it is not calcified?

this is jrnnifer again and i forgot to say that i discovered that you can have radiation on the lungs is is an advanced form of radiation callrd TomoTherpy.
