Further to my first post (4 minutes ago!) I just realized a couple of things I meant to ask - but i can't figure out if I can edit the previous post. The CT scan indicates it is confined to the right lung, but how accurate are they? I'm scared it might actually have spread, though the report said the lymph nodes outside the lung eg armpits etc were showing clear, lung wall showing clear etc. The other thing that worries me (and the main reason for going north to the specialist clinic) is that if the tumour is already T4 does that mean it is aggressive, and growing fast?? Hence could spread fast outside the primary site? And how fast do they spread?
