Elder snakes and masses

[Bogertophis]

I guess what worries me most is it feels like it's attached to a rib at around the area of the heart.
He's my first BP and he made the crazy leap from NY to CA life with me...on top of a bunch of other stresses at that time.

I just wanna be prepared since I've got enough medical stress and possible upcoming things for myself as well @_@;
Being a projecting mom. Especially after weird mammal health issues over the years.

Honestly, I've lost a snake (a rosy boa) in the past to a mass in the heart area- wasn't a surgical option. It never hurts to be hopeful but still prepare for the worst. And you still have to take care of yourself too- sometimes you can only do so much, so don't beat yourself up if that's the case here. Is he still eating? I assume he's not really symptomatic yet? This could be slow growing, or fast.
