i hope someone can put my mind at ease. I had a really severe uti early last year and an ultrasound which did not show any issues. I had what I thought was another uti late last year but my gp saw blood in my urine and thought it was due to kidney stones. I had another ultrasound which showed a small 3cm mass on my right kidney. Following an urgent appointment the consultant he arranged a ct scan with contrast . He said that because nothing was there in the earlier scan that he didn’t think it was anything serious. By that I took it to mean, not a cancer. Two weeks after the ct scan I have been contacted to say that they wish to do a biopsy. I have an appointment next week with the consultant to discuss this. How worried should I be? You
