aFinal answer:
If a lesion resembling a fibroadenoma grows by 20% on follow-up ultrasound, seek medical advice for possible further imaging, a biopsy, or surgical removal to ensure proper diagnosis and treatment.
Step-by-step explanation:
If a lesion that looks like a fibroadenoma grows by approximately 20% on follow-up ultrasound (US), it is important to consult with a healthcare professional. A fibroadenoma is a benign breast tumor common in young women, but any significant changes in size or characteristics merit further evaluation. The usual approach would involve a multidisciplinary team, which may include a radiologist, oncologist, and a surgeon. Additional imaging, a biopsy, or even surgical removal could be recommended based on the patient's history, risk factors, and current findings. It’s crucial to rule out malignancy or other conditions that may require different management strategies.
