Thank you so much for your quick reply! Yes, fingers crossed it is scar tissue which we know can be very common after radiation. You are right, there is definitely the fear factor that comes up when the word biopsy is used because it reminds us of what we already went through. I will let you know how it goes! Yes one would think a total of 45 days of on and off antibiotics within the past 5 months would kill any infection. Glad all is well with you! Best : )
