sometimes, we have to be our own advocate. Personally, I would address your concern to your doctor and just ask why they don't just biopsy it for you. If your doctor gives you a reasonable explanation, then you have your answer. If not, then say thank you for your time, but I need to find a doctor that will care for MY needs. I do believe your doctor thinks he/she is doing what is best for you. If you're not feeling the love, then it's time to move on. Listen to your gut - that's where your intuition is located. If it doesn't feel right to you, then it probably isn't best for you. Keep us posted. Please?
