I was diagnosed with leukoplakia about 3 years ago after a biopsy. At that time no doctor wanted to operate. My ENT said lets watch it and come back once a year. He also told me that only 1% turn into cancer. Well, I had to be that 1%. Things stayed pretty stable until one spot turned very sore, and was diagnosed with squamous cell carcinoma on the tongue. Can't tell you what to do in your case but I would get a second opinion somewhere. And if it turns out you don't need surgery now, keep an eye on it, have a doctor check it out regularly. Good luck!
