Explanation:
Patient is under the age of 40 and therefore USS is first line imaging investigation.
In this patient the diagnosis is likely to be a fibroadenoma of possibly a cyst (although a bit young for cyst) If under 25 then imaging alone maybe sufficient for diagnosis of a fibroadenoma.- Royal College of Radiologists Breast Group
