Please explain to me why a mom nursing a 2 month old should stop breastfeeding for 1 1/2 days after having a mamogram? This poor mom was told by her OB not to worry about a lump in her breast (slightly smaller than a golf ball).....it is nontender, doesn't change with nursings. She was told that since she is only 28 y/o there is no reason to be concerned. She took my advice and thereafter went to her primary physician and he referred her for testing. The radiology department first told her that she should stop nursing 2 days before the test....no reason why. I told her she should empty her breasts prior to the testing. I also went over to radiology and inquired and was told, "Oh, she should not nurse for 1 1/2 days off that breast being tested because of the radiation it will get".....I just don't get it?
