Good you got checked out. Good friend of ours had to have his left kidney removed last September due to cancer - contained to just the kidney. He's 77 and is doing just fine, still beats us at cards and dominoes.
The first day the doctor says cancer it's pretty tough. I spent countless hours doing internet searches when the told me I had leukemia at 50 especially since I've had family members pass from the same thing plus other cancers. By the grace of God I've already passed the survivability rate with treatments and going on 12 years now. Stay strong and pray.Nobody wants to get cancer but I got one of the better ones to get. The 5 year survivability rate of kidney cancer is 95% as long as it didn’t spread to the lymph nodes (and if it did then the rate goes down to 75%)
