My experience with the NHS is there is not a constant dialogue with the consultant. The frequency of intervention is dependent upon the stage of your treatment. You have to remember that the timelines of treatment can be long and drawn out, people are simply compressing those timeline down to key points.
Since March I have seen a urologists 3 times and had 1 phone call. But that is because I was going through diagnosis.
I believe everyone should be assigned a uro-oncology nurse. I have 2. One at my initial local hospital and one at my treatment centre. They both are very good at answering questions and providing advice.
