He's going to be ok!! I will pray. My husband was diagnosed with kidney cancer last year, and had to have his entire right kidney removed. Parts of the tumor had increased to his lungs. (That isn't uncommon or necessarily horrible.) A month after surgery it was shown that the tumors in his lungs are now curing themselves since the main tumor was removed! He goes back for another checkup this month. :) Kidney cancer is one of the "better" cancers to be diagnosed with. It is easily contained, and can cure itself after removal of the main tumor. Your dad is going to do great. Try to stay calm pray, and let your dad know how much you love him.
