What surgery to choose

I was diagnosed with bladder cancer in 2007 i had all the tumors removed but no guaranty they would not return my second opinion was a joke so i did nothing i recently went to the cancer treatment centers of America and again was diagnosed with a very aggressive cancer although it is still contained in the bladder it is starting to invade the walls and needs to be removed everyone i have talked to recommends the external bag i could sure use some insight on this and other options
