Recent biopsy march says cell reaction just had a mammo&ultra still adnormal this hs been going on for 1/12 years doctor wants to do a part mast agree?

Not w/out more info!: I'm assuming you had a 'core needle biopsy' where an ultrasound was used to see the abnormal area, and numbing medicine injected, and a needle took several samples of this area. If you have not had this done, would be next step in all major breast centers. I would never recommend a partial mastectomy until a precancerous condition/cancer had been proven. Get 2nd opinion from breast surgeon.
