Hi Carmine,
Get a few more opinions if it makes you feel comfortable. You should be happy with the institution you are choosing for your care.
But,
If the Cancer has spread into the muscle it is high grade. In my opinion, (and since you are asking for opinions) Get the surgery. It WILL spread left untreated, and even after months of painful treatments you are likely to lose it anyway... Unfortunately even with removal. There is still quite a bit of follow-up, but you are getting the heart of it out before it goes anywhere else.
Now, as for where you should do it? That is a real personal choice I have found, and as much research should go into that as goes into finding second, third, etc...opinions. You are so close to a variety of MAJOR Hospitals, actually centrally located...NY, Penn, Wash, Maryland, Virginia...Be thankful you are where you are, some people on this site are not so lucky to have so many great choices in their backyard. You can be very selective...
Keep us posted,
Karen
