Yes it’s absolutely quite normal to wait a month for your biopsy, I truly understand where your concerns are coming from and that’s very understandable. I know that the waiting times can vary depending on the doctor and their schedule but I believe that they go over their cases to make sure that you are looked after within an appropriate timeframe. I had to wait three months because it was in 2020 and everything was still chaotic and super stressful, best wishes for you and good health.
