If he was cancer skip the tests and stuff at the local hospitals and Drs. Get a referral to a cancer center. Don't wait - cancer is cancer - while you're waiting it can grow and spread. Despite the fact that they removed it there may still be some left. I had a biopsy on the 10th of December, was diagnosed the 20th, had my tests, the 21st, results same day, had a referral that day MRI the 6th of January ( would have been sooner but christmas shutdown interfered ) appointment with specialist January 12, surgery Feb 4th. So 6 weeks start to finish. Good luck!
