Milana,
C'est en effet une sacree coincidence... Doctor Bouchi is having his office for private appointment in the 16 Arrondissement. You can book the appointment directly through Doctolib.fr if you have French Social Security. He was absolument categorique i should not have any Biopsy with negative PET. He is working all summer i believe and, since it's a "cabinet prive", you should be able to get an appointment in days : Cabinet médical 113 VH
113 Avenue Victor Hugo
75016 Paris = Docteur Jihad Bouchi
If you go to Doctolib, you will be able to book the appointment with him in no time, i guess calling the office is another option. He said most likely Bronchial radioscopy are never going to be able to get results and the ratio risk/benefit is important... I recommend you to see him, he is really great, i wish you the best and please give us some news asap. Best regards
