if best suggestion for now is don't express and recheck in 1-2 months?
Surgeon didn't feel biopsy was urgent and admitted scarring from biopsy
would
make site more difficult to check in the future.
>>>this type of discharge from a once lactating breast can be very normal
several years after the lactation.   If your mammogram is OK and you are at
low risk for family history, observation may be the most prudent course.

If you want the option of another test, an experience international
radiologist or a radiologist with experience, can do a ductogram.
 Basically they use a very small tube to try and pass it into the milk duct
where the discharge is coming from and then inject a small amount of
radiocontrast material back into the duct to visualize it better.  This is
the same principle that is used to visualize many "tubes" in the body from
blood vessels to ureters to salivary ducts to ovarian tubes.  It is not
commonly done but it can be done.  It would be my choice to do this before
a biopsy, once again assuming every thing else is OK
