Here is a link to a site that has a whole series of interviews with Dr. Bela Denes (Urologist). I haven't looked up his credentials but when you go the the page you can what questions are asked/answered in each video in the series. I only watched a couple so far.
The ones I watched so far are called "Bladder Cancer prognosis" and "When to get checked for bladder cancer".
Video Series: Bladder Cancer Q&A
In the prognosis one they talk about things like differences in men's and women's bladders. Did you know women have thinner bladder walls than men? It also talks about women having 5-10% higher mortality rate and some reasons behind that. It also explains stages and grades and the like.
While I wouldn't consider this to be anything in depth, it seems like a reasonable high level overview and is addressed to lay people. I tend to like the nitty gritty doctor targeted material more but this seems like some reasonable educational material.
I have no idea how accurate the information is and some things seemed a bit too over-generalized to me, but it may be helpful to folks so I'm posting it here.
