Three years ago I had a 14 cm cancerous tumor (chromophobe RCC) on my right
kidney so I had a right radical nephrectomy. It was only stage 2. For about 2 weeks now, it has felt like there's a mass on my left side now (I recognize this feeling because its the same as before). I just had a clear ct scan in may. It seems impossible that a tumor could grow on my left side fast and big enough for me to feel it by now. It's uncomfortable and hurts off and on.
