I went to the pulmonologist today. He feels confident that the masses that I have are so small that they are unlikely to be cancer. We will repeat the cat scan and reassess later. They are too small to biopsy without a thoracotomy and he says that the risk way outweighs the benefit.

As far as my shortness of breath, he thinks that it is probably due to my myasthenia gravis. I have breathing tests scheduled to be sure.

So it looks like I'm not going to croak any time soon.
