Mass concern

Hello everyone.

I recently had a mammo and an ultrasound where the doctor noted, “there is an irregular mass with microlobulated margins measuring 9 x 9 x 12 mm seen in the left breast at 6 o’clock. The echogenicity of the lesion is heterogeneous. No vascularity is seen within the lesion.” Additional testing, specifically an MRI, has been recommended. 

Has anyone had a similar scenario that turned out to be breast cancer?

Hi waveback1983 

Thank you for posting.  

It’s understandable that you would like to know what the possible diagnosis will be from the mammogram and ultrasound results you have been given. It can be difficult to understand the medical language and what this may mean for you.  

An MRI scan is sometimes recommended if the breast team feel the area wasn’t seen well on mammogram, or more information is needed to make a diagnosis.  

It’s natural to worry if this lump could be breast cancer. It may help you to know that there are many benign (not cancer) conditions that can cause lumps in the breast.  

You may find it helpful to contact the breast clinic, or screening centre, where you had the mammogram and ask to speak to a nurse to discuss your worries.
