Confused

[Byager]

On June 15th I had a mammo and an ultrasound done. Report stated round lobular heterogeneously hypoechoic soild mass 0.5x0.5x0.5. Small group of microcalcifications projecting superior and posterior to region of palpable abnormality. Inderterminate in morphology. I went to the breast surgon today, he used a needle to take cells from the mass to be sent to the lab. He told me that he would have the results in a week. If the labs come back neg. he does not see any reason to biopsy the microcalcifications. Does that sound correct? I am very worried about the microcalcifications. Thank you,

Dear Byager, Microcalcifications are small calcium deposits found within the breast tissue. Microcalcifications in and of themselves are not a condition that would become cancerous however they can be a sign of a problem that may need further investigation based on their appearance on a mammogram.  For instance microcalcifications that are more scattered are probably due to a benign (non-cancerous) cause, a “cluster” of microcalcifications may increase concern that there may be an underlying tumor.  The information from the needle biopsy will be put in context of the findings of the mammogram and ultrasound.  The decision as to whether further sampling is needed if the result is a non-cancerous finding would be based on whether or not the biopsy was thought to be representative of the suspicous area.
