Eric,
I'm glad you're being proactive regarding your suspicious lymphnode, but sorry to read about your missed job opportunity and a chance to move back east. I'm affraid that if you share your challanges with other future employers, they may be just as reluctant to hire you, though hopefully not as cheesey about it. There is some debate over how much to share with a prospective employer as we all want to be forthright and honest about our journey, but this may not be the best policy where an employment search is concerned.
