Well, what a difference a day makes. Finally, I got some real information from my brother. They aren't doing a medial stenectomy. When he had his PET scan not only did the one nodule show "hot" but so did the lymph nodes near his groin. They are going into the groin tomorrow(Fri)to biopsy the lymphs. They think it may be sarcoidosis (not sure of the spelling)I will keep you posted. Thanks again.
