I've Had 2 Urologist Diagnose Me With RCC - 2.4cm,

I've had 2 urologist diagnose me with RCC - 2.4cm, then back out, I've had 3-CT's, MRI and ultrasound, saying lesion enhancement pattern in vasculartity. Vascular lesions can be identified because they enhance to the same degree as the vasculature. With the exception of inflammatory or vascular abnormalities, all enhancing lesions that do not contain fat should be presumed to be malignant. why aren't they taking this OUT of me??
