Which tumor is notably associated with a radial scar?

• A. Carcinoma in situ
• B. Tubular carcinoma
• C. Lobular carcinoma
• D. Invasive ductal carcinoma

Answer: (B)

The tumor that is notably associated with a radial scar is tubular carcinoma. Tubular carcinoma is a special subtype of invasive ductal carcinoma characterized by small tubular structures that are well-formed and are typically low-grade. Radial scars are benign breast lesions that can be identified on imaging or histological examination, and they have been found to have a noteworthy association with tubular carcinoma. This connection is significant because the presence of a radial scar may suggest the need for rigorous evaluation to rule out any associated malignancy, including tubular carcinoma.

In contrast, while other types of carcinoma might interact with a variety of benign breast lesions or even present in the context of radial scars, tubular carcinoma stands out due to its specific relationship with these lesions, which has been demonstrated in several studies highlighting their co-occurrence. Understanding this association helps in breast pathology and informs management strategies for patients who present with a radial scar during diagnostic imaging or biopsies.
