What imaging modalities are typically used to establish the initial diagnosis of breast cancer?

• A. Ultrasound and Mammography
• B. CT Imaging, Bone Scans, or PET-CT
• C. MRI and Sputum Cytology
• D. Sputum Cytology and Blood Tests

Answer: (A)

Initial evaluation of a suspected breast cancer relies on imaging that can detect suspicious lesions and guide tissue sampling. Mammography is the standard first-line imaging test, able to reveal masses and characteristic microcalcifications that raise suspicion for cancer. Ultrasound complements mammography by further characterizing the lesion, distinguishing solid from cystic masses, and providing a guide for needle biopsy. Together they form the typical initial imaging approach. Other imaging like CT, bone scans, or PET-CT is used mainly for staging to look for spread after a cancer is suspected or diagnosed, not for establishing the initial diagnosis. MRI can be helpful in certain situations (such as evaluating extent, very dense breasts, implants, or high-risk screening) but is not universally used as the first-step diagnostic imaging. Sputum cytology and blood tests do not establish a breast cancer diagnosis.
