12 month mammogram and new lesion found.

i went for my 12 month mammogram and ultrasound today and they have found a 2cm lesion on the opposite breast which needs to be biopsied. I am hoping and praying that it is not a new cancer. I’ve had a prior biopsy on that breast which was benign but I can’t even feel this lesion. The one I had last year was a 2.5cm lesion and was easily felt. I surely couldn’t be that unlucky. I had lumpectomy and radiotherapy with the right breast and am on anastrozole now. I’m really not ready for this roller coaster ride to start again.
