@part, Typo I think. ? 1 cm mass in Right breast? Also, how did they mammo your left side where you had the mastectomy? My surgeon & oncologist do manual exam on my right mastectomy side. Mammo & MRIs on left. I alternated mammos and MRIs every 6 months.
Blessings to you on upcoming biopsy. Please let is know his things turn out. 🙏🏼
