In which situation is breast MRI screening recommended as an adjunct to mammography?

• A. In a woman over 50
• B. In a woman with a family history of breast cancer
• C. In a woman with a BRCA gene mutation
• D. In a woman with dense breast tissue

Answer: (C)

Breast MRI screening is particularly recommended as an adjunct to mammography for women with a BRCA gene mutation due to the significantly increased risk of breast cancer associated with this genetic condition. Women who carry BRCA1 or BRCA2 mutations have a substantially higher lifetime risk of developing breast cancer compared to the general population. As a result, standard screening methods, like mammography alone, may not be sufficient in detecting cancers early in these individuals. MRI has a higher sensitivity for detecting breast cancers, especially in women who have dense breast tissue, which can obscure lesions on mammograms. Therefore, using MRI in conjunction with mammography allows for more thorough surveillance and early detection of breast tumors in this high-risk group. While family history of breast cancer can contribute to a woman's risk, it does not equate to the same level of risk as having a BRCA mutation. Women over 50 are generally at higher risk due to age, but MRI is not routinely recommended based solely on age. Dense breast tissue can complicate mammogram readings, but an established genetic risk like a BRCA mutation necessitates more sensitive imaging methods. Thus, the recommendation for breast MRI screening is specifically highlighted for women with a BRCA gene mutation owing to their unique risk factors.
