Thank your for you input here. I too had an inconclusive biopsy. Recommendations are now for surgery or wait and see. I want another biopsy. I've had 2 opinions from well known hospitals. I think I'll persist in requesting another biopsy thanks to your kind words. How can they treat what they can't define? I understand biopsy can risk nerve damage (nerve sheath tumor likely) but I don't know the odds of that. Do you or know where I can find a percentage of time where this can happen?
