What is the purpose of preoperative localization?

The purpose of preoperative localization is specifically aimed at identifying the exact location of nonpalpable lesions, which may not be detectable through physical examination alone. This process is essential in the context of surgical planning for patients diagnosed with breast cancer or other breast conditions where a lesion cannot be felt during a clinical examination.

By utilizing imaging techniques, such as mammography, ultrasound, or MRI, healthcare providers can accurately mark the location of these lesions prior to surgery. This allows the surgeon to target the area effectively, ensuring that all cancerous tissue is removed while sparing as much healthy tissue as possible. Preoperative localization helps improve surgical outcomes by enhancing the precision of the procedure.

In contrast, assessing tissue health, evaluating the extent of a tumor, or obtaining a biological sample serve different purposes within the diagnostic or treatment process and do not directly address the localization of lesions that cannot be palpated.
