Hi,
Experienced radiologists are quite able to identify typically benign breast calcifications depending on their form and pattern.However, calcifications that grow in a cluster (grouped)are suspicious because they sometimes cluster around a mass.The appearance of clustered calcification on x-ray, gives clues to the radiologist,but not definite answers,so it is standard procedure in most cases to biopsy the area because it's the only way to determine if cancer is present.
A family history of breast cancer doesn't mean that you will also have the same disease,but it can increase your risk.Keep in mind that very often biopsies done on clustered calcifications return a benign finding, but if unfortunately it does not,then the cancer would be at a very early stage and very curable.
Best wishes and good luck!...
Thanks for your information it has helped, I guess I will not know anything else, whether I need a biopsy etc. when I get the results of the test from yesterday. Will keep you posted.
