Welcome @mignon! I have nothing to add to the information all of these wonderful people have offered.
I was diagnosed in August of 2016 and quickly progressed from Stage 2 to Stage 3, now 3b. Mayo Clinic Rochester has been my Friday ritual since moving back to Minnesota in 2018. Everyone there has been so supportive and caring. I learned the more information I can provide them, the easier it is for them to rule things out! You will be glad to be there.
