My gynecologist recommended a breast cancer risk assessment due to my family history (sister and maternal aunt with past history of breast cancer - both are breast cancer survivors). The results of that assessment showed that I am high risk of developing breast cancer within the next 5 years, and that’s why the yearly MRIs are being done. Also, with dense breasts, the routine mammograms may not pick it up if it occurs. The symptom of sore nipples does not seem to be a concern to the breast surgeon as there is no discharge, no dimpling, no inverted nipple, etc. It only concerns me because it is a new symptom that has developed this year.

After reading these posts, I’m thinking this is most likely due to post-menopausal hormone changes.
