Newbe here but not to RCC.
6 years ago, at age 54, I was diagnosed with a right renal mass. After three urologists told me to have surgery ASAP, I let Mayo Clinic in Arizona take a stab at it. (Plug for Mayo here; they are very very good at what they do). The doctor went in with robot surgery and at my request tried to save part of the kidney. Unhappily this was not possible so he performed a radical nephrectomy and also removed three lymph nodes. Next night the pathology report was back. Renal Cell Carcinoma, Chromophobe, 7.5 cm tumor, Furman level 3. T2a, N0M0.
