Hi, it is very encouraging to hear it may not be cancer. Glad the doctors are following up with a broncoscopy and PET scan, that should give more information. As for coping, that's a tough one .... Breathwork (you can youtube various methods of breathwork for stress, relaxation, etc.) helps me calm down. Were you always short-tempered with your wife or is this something new with what you are going through? A possible diagnosis of lung cancer can cause so much stress. Thinking of you both! ~ Alisa
