A search of the SB doesn't reveal any threads discussing this particular question. I am scheduled for removal of the upper right lobe in a couple of weeks, due to lung cancer (yes boys and girls, smoking really is bad for you!). Perhaps my priorities are off, but one of my main concerns is whether I'll be able to dive again. I understand the actual decision will require consultation with my own doctors, and preferably also a local doctor with scuba knowledge, but I'm also very interested in the current thinking of those in this community who know about such things (especially those with the letters MD after their names). Thanks in advance.
