The fact it has blood supply makes the radiologist think that it need s to be biopsied thus being a birads 4, and its good that the margins are not irregular that kept it from becoming birads 5 which is highly suspicious for malignancy.
Hi,
To get an answer to your question from a nurse, you need to post it on the Breast Cancer Forum, as opposed to the Breast Cancer Support Forum, which is not monitored by a nurse, it's only patient to patient. If you got to the main page, look at the top and you will see Breast Cancer Forum. Go to that page, and you can post a question.
Did you have a mammogram also?
