Hello to all , one year ago I was I had a grade 1 non invasive tumor removed, size 10 mm. Just made it to a year and today on cystoscope they found a small tumor , approx 5 mm, three months it was not there,I guess I am lucky I am checked every three months. My doctor told me he would like to do the procedure on removal in the office seeing it is so small. My questions is have any of you had this done in an office ? And what can I except regarding discomfort. I was also told it is common for a reoccurance, and not to worry. I know I am very lucky the tumor is small, but a worry it is.
