Perhaps my choice of the words "garden variety" was a bit off....What I meant was that the type that you have,
urothelial carcinoma, is the most common. This link describes the types (doesn't mention melanoma)

If you go to our home page and click on SHOW ALL on the box at the top left, you will find a wealth of information on bladder cancer.
Since you have high grade now, BCG is the way to go. It has been shown to be highly effective in high grade bladder cancer.
It would be interesting if you could obtain the records from your initial diagnosis so many years ago!
