I am 70 y.o. woman. Without asking my permission, neither even telling me, in the time of core needle biopsy, doctor included in my breast Neoadjuvant. This make my breast immediately shrink pretty substantially. Lab received samples that been taken right before N-t installed. Diagnosis: Infiltrating mammary carcinoma with lobular features. Nothing diagnostic of lymphovascular invasion identified. Doctor insisting on full mastectomy, but I am not agree. My question, is: how dangerous for me if what doctor installed, would continue stay in my breast? My breast looks weird, like there're some different parts in it. Is there any negative influence on my health, if nothing else on my breast would be done? Thank you.
