Final answer:
Lipomas usually exhibit a well-circumscribed, radiolucent appearance on mammograms. The correct answer is (C).
Step-by-step explanation:
Lipomas usually exhibit a well-circumscribed, radiolucent appearance on mammograms.
A lipoma is a benign tumor composed of fat cells. On mammograms, lipomas typically appear as well-defined, encapsulated masses that are radiolucent, meaning they appear darker than the surrounding tissue. This is because fat has a lower density and absorbs less X-ray radiation, resulting in a less dense appearance on the mammogram.
In contrast, malignant tumors in the breast, such as breast cancer, typically appear as irregular, dense masses on mammograms. They may also exhibit spiculated margins and architectural distortion. However, these features are indicative of malignancy, not lipomas. Therefore, The correct answer is (C).
