again, thanks all.
dad had PET/CT today. we'll get the results tomorrow. here's to hoping that only the lungs are at issue---as his first CT initially suggested.
It also looks like we are going to get a second opinion (from a reputable onc. who was recommended by two independent sources). I think we have good reason to as we've gotten some mixed info. For instance, dad's ct and xray shows nodulation on both lungs, but the onc. said based on the ct (and corresponding report from ct guy who he described as phenomenal) he believes the cancer is only in the right lung (which, I suppose, is why he suggested IIIB staging). This seems second opinion worthy in and of itself.
Of course, this could be moot after tomorrows PET/CT results.
on a side note, I've noticed that since this started I'm hyper aware of this balancing act where I'm trying to be strong, but trying to avoid that strength from morphing into a subtle form of denial. so million dollar question: what is it to be authentically strong in the face of this?
