Off Topic, but can i ask a medical question here on this forum?

Ya, chemical exposure.
I think back and wonder if that has lots to do with my "issues"?
When i was a kid, i started working in a tool manufacturing company, that used all kinds of nasty solvents in cleaning up the manufactured parts.
I remember a nasty cleaning solvent they had us use on the wash rack, cleaning the F-4 Phantom's on a regular maintenance schedule.
Plus 30 years in the auto mechanic field, being around every nasty fume, vapor, chemical, that you can think of.
And back then, we were never trained, told, in wearing gloves, respirators, masks, safety equipment, in doing your job.
So, who knows, if all that is a contributing factor in developing cancer issues.
Doctors can't prove it, for certain, and i certainly can't, either.
What a catch 22.
