The key findings in the stem are: - 29 year old woman with a painful mass in her left breast- No fevers, chills, or changes in the right breast- Last menstrual period was 3 weeks ago- Ultrasound shows a 1.75 cm well-circumscribed anechoic mass with posterior acoustic enhancement- Patient is anxious and wants further testingThe ultrasound findings are consistent with a simple cyst. In a young premenopausal woman, a new palpable breast mass has a high likelihood of being a benign fibroadenoma or cyst. The ultrasound confirms this is likely a cyst. The options include fine needle aspiration, mammogram, MRI, excisional biopsy, and core needle biopsy. Fine needle aspiration is the least invasive and quickest way to obtain a sample of the cyst fluid and confirm the diagnosis. It avoids unnecessary radiation exposure from mammogramMRI in this young patient. Excisional and core biopsies are more invasive than needed to diagnose a simple cyst.A: Fine needle aspiration
