understanding ultrasound results

[Cilghal]

I was recently diagnosed with a 1.3cm relatively well circumscribed mass via mammogram. They followed with a breast ultrasound. From time of findings to appointment with the breast specialist is 3 weeks. I am making myself sick with worry. I am a 45 year old NP so comfortable with medical terminology but do not understand what some of this means. It is a heterogenous solid/cystic mass. Measures 10x8x13mm- It has soft tissue components and there is vascular flow to this area. The border is macrolobulated. There is some through transmission. It was categorized a Bi- Rad 4 with biopsy recommended.  I know the vascular flow is bad but don't know what it means. Could you explain or point me to a good resource to get information?

Dear Cighal:  The features mentioned on these reports are all descriptive features of this abnormality.  A complex cyst, or a cystic mas with solid components often requires further evaluation to be certain that there is nothing concerning within the solid structures.  A BIRAD 4 means that this is a suspicious abnormality. Most category 4 abnormalities are benign but may require biopsy since this category can be malignant in 25-50% of cases.  It may be reasonable to call the breast specialist to see if the appointment could be moved up so that you can begin to get some answers and eliminate prolonged worry.
