15 years out with new finding

I will be 16 years out from diagnosis on 5/13/26 and had my annual diagnostic mammogram yesterday. Radiologist told me there was a new finding on my non cancer side so he did an ultrasound. It is less than a cm and he stated it appears to be in a duct. Given my history, he wants to do a biopsy which isn’t scheduled unto 3/12. Prior to my initial diagnosis in 2010, I had an intraductal papilloma removed on the right side about 8 years prior to my diagnosis. When I was diagnosed with Stage 2B IDC with 3 of 17 nodes involved , they found another intraductal papilloma which they removed on the cancer side at the same time they performed the lumpectomy and axillary node dissection. I had 6 rounds of TC chemo and 35 days of radiation including boosts to the axillary and the clavicle. I did 3 1/2 years on Tamoxifen and 7 years on Letrozole. My last MRI was in August 2024. My last diagnostic mammogram was in February 2025. I hate this disease. I really try not to worry but I have had so many friends diagnosed since my own diagnosis and have lost 4 friends who supported me through my initial diagnosis. Thank you for reading! Anyone else with a similar situation?
