In 2012 I had a tumor removed from my kidney. The tumor had started inside the kidney and extended out close to my liver. My urologist said it was one of the largest tumors he's ever removed. However, afterwards, I was told that the tumor was benign and I believed this meant it was not cancer. A couple of weeks after the surgery, I returned to the hospital due to an infection. I was told by a different doctor that the tumor was considered cancer due to how large it was and how far it had extended from the interior of the kidney. I'm now confused as to whether or not I actually had "cancer" or just a tumor that could have become cancerous.
