Can the radiologist tell breast cancer from a fibroadenoma during a ultrasound, or do you need a biopsy?

Will have some idea: Correct diagnosis is possible only by pathological examination ( need biopsy , and pathologist makes it ).

Usually yes,: He can distinguish fibroadenoma from cancer, but not always. Biopsy is the only way to know for sure. Ask your doctor what he recommends, after he reviews the study with you.

There are certain: imaging features that can used to be reasonably certain that a nodule is a fibroadenoma, and assign it to the BIRADS 3(probably benign, less than 3% chance of malignancy) short interval follow up category, or sometimes BIRADS 2(benign, less than 1% chance, no follow up), but ultimately "fibroadenoma" is a histopathologic diagnosis based on a biopsy. Usually they can be managed without biopsy.
