What exactly does this mean?

Hi Folks

Steve has just received letter clarifying situation regarding his latest cysto - 12 months after first diagnosis and Turbt. He has had 6 plus 3, plus 2 doses of BCG.

They quote 'There were two velvety patches on posterior wall, near to the dome and congested areas on both lateral walls. Each have been biopsied with diathermy. Histology of three separate biopsies shows urothelial atypia only without any definite evidence of carcinoma in situ (pre-cancerous changes) or malignancy. Follow up cysto in 3 months and 3 further doses of BCG'.

I just wanted your view on this. Obviously, we are pleased but what is 'atypia'?

Also, I worry constantly from what I read here about understaging etc, but his Urologist is the 'top' guy at his hospital and their path departments are supposed to be excellent so should we just hope for the best.

Thanks

Ceri
