Small hard lump in breast after prophylactic mastectomy- trying not to worry...

Thanks Brenda- I will have to wait until Monday when I see my surgeon anyway but I'm sure she'll order one if she's unsure at all. I did have some lumps that felt a lot like this one a few 
months after my surgery and she could tell right away they they were stitches so fingers crossed. Good luck with your results- is it for a similar thing?
