Your surgeon or oncologist will make the referral. I had my result before surgery based on my biopsies. In my case they had enough tissue to do the typing.

The oncologist was looking to see my numbers ( aggressive or not so aggressive). Had my numbers been higher she would have suggested chemo before surgery to shrink any nodes to minimize a major axillary removal.

Ask about this on the 13th. Often it’s done with surgically rendered tissue.
