I know my cancer was very rare, and as much as I had hoped that these noduales are not cancer, I might have to think they r. I am waiting for biopsy. Pet says no cancer anywhere but lungs. Today I did test positive to a pregnancy test, which can happen with choriocarcinoma, and testicular and breast, and ovarian, but have not heard anything about lung cancer causing this. I know I should not b speculating, but I can't help it. Anyway anyone else have this happen?
