[|AI|]  Welcome to Chat Doctor .1. It looks like a suspicious mass lesion in the breast for which your doctor asked for a followup mammograms/ultrasound.2. If you still feel the lump and pain - approach to the same doctor with a fresh ultrasound (to find out the extension of the lesion)3.then the needful action will be taken.4. Yes, if required an excision/mastectomy -complete or partial depends on the involvement and type of the lesion. Anything to ask ? Do not hesitate. Thank you.
