Which statement about MRI in breast cancer screening is supported by the material?

• A. MRI replaces mammography for all screening
• B. MRI is used only after a breast cancer diagnosis
• C. MRI can supplement mammography in those with implants or prior treatment
• D. MRI is not useful in breast cancer screening

Answer: (C)

MRI adds value to breast cancer screening by serving as an adjunct in people where mammography alone may miss things or be harder to interpret, such as when implants are present or after breast-conserving treatment. Implants can obscure portions of the breast on mammography, reducing sensitivity, and scar or post-surgical changes after treatment can mimic or hide recurrent cancer. MRI provides superior soft-tissue contrast and can evaluate implant integrity while also detecting additional cancer foci not seen on mammography. It is not used as a universal replacement for mammography in all screening scenarios; mammography remains the first-line test for most women, with MRI added in selected cases like implants or prior treatment.
