Fabulous,
A few short comments I hope are helpful.
Every question you have is a fair question to ask a potential doctor. Your doctor needs to respond to your concerns so that you can make an INFORMED decision about your treatment. My questions include the doctor's experience, who I can call 24/7 if there is a problem, and if a particular treatment is recommended I want to know ALL about the other options, and what to expect after and during recovery. My body and questions are important, so are yours. Yes, I have declined to be treated by well respected doctors who "would not make time to answer questions."
As I understand it, squamous cell cancer (SCC), being far less common than Transitional Cell Carcinoma (TCC), has less research to support chemotherapy prior to bladder removal. Again, it is a fair question to ask WHY one doctor approves prior chemo while another does not. Many doctors have 'favorite' procedures or practices.
Number of bladder removals a doctor performs is a fair question. The minimum number has often been discussed or debated in this forum. Important but not mentioned, is the urinary diversion you would prefer, if possible. Search this forum for RC or Radical Cystectomy and Diversion.
A google search for reliable sites, looking for Squamous Bladder Cancer Treatments will offer some information on the subject.
To get what you want, asking directly produces the best answers. But first, do ask why chemo is not offered, or why it is not offered "at your age".
Feel free to ask ANY questions in this forum. No doctors here, just others with bladder cancers who have a range of experiences.
We do disagree on doctor personality. I want doctors who support (rational) patient involvement.
Best
Jack
