Paula:

     If I understand correctly she has a benign tumor ....

     Why the rush to remove?

     the textbook of breast disease    by john isaacs.. mentions that they
are softerduring lactation.... he also describes them as secreting a fluid
but does not mention this as harmful.

      I can not think of any reasons why she should not bf on the other
breast....hormone levels are going to change in the course of lactation...
You have firm ground with the ob on your side,,,,
