The Halsted technique is a surgical method primarily used in the field of oncology for breast cancer treatment. Named after the American surgeon William Stewart Halsted, this technique emphasizes meticulous dissection and the preservation of surrounding tissues to minimize damage. It often involves the removal of the entire breast along with nearby lymph nodes, aiming to ensure complete cancer removal. This approach is significant for its focus on reducing the risk of cancer recurrence. By carefully excising the tumor and surrounding tissues, the Halsted technique helps maintain the integrity of the remaining structures, which can lead to better postoperative outcomes for patients.
