Hi Sammy,
There's a lot to learn when this is all new. Read the pages about superficial bladder tumors and staging and grading to get an idea of what might lay ahead. The path report...ask what exact stage and grade the tumors were, how many. I'm almost positive that the doctor is referring to local chemo, placed in the bladder, there is more info on the subject on the website as well.

Keep asking questions! Try not to panic. Also, try to make sure your mother has a good doctor she is comfortable with as this is the beginning of a long relationship. The survival statistics are excellent for low grade tumors, and this is a very treatable cancer when caught early.
All the best,
Wendy
