Hello and thank you for the question. Sorry for the delay in response. Have you had the follow up as of yet? A Bi Rad score of 4 would indicate a need to go ahead and have a biopsy if they suggest it. It very well may and likely will turn out to not be cancer. However, in an abundance of caution, it's important to make sure. You have more than one thing going on with the microcalcifications and lesion. Since there was a delay in this situation, please update us and we'll go from there.
