北京大学深圳医院乳腺甲状腺外科团队为一名37岁患者成功实施腔镜下全乳切除联合即刻乳房重建手术1。该患者被诊断为多发乳腺导管原位癌，通过在腋窝位置设置切口、保留乳房皮肤和乳头乳晕、植入假体重塑乳房形态等技术手段，在实现肿瘤根治的同时保留了乳房外形1。医院自2020年开展腔镜乳腺重建以来，已完成数百例此类手术1。
乳腺癌的高发趋势值得关注。国家癌症中心2025年统计数据显示，我国乳腺癌年新发病例预计突破42万例1。与欧美国家相比，中国患者确诊中位年龄为47岁，比欧美早近10年，其中40岁以下年轻患者占比约20%1。专家指出，早期乳腺癌的5年生存率超过90%1，提示早期发现的重要性。根据《中国年轻乳腺癌诊疗专家共识（2026版）》，女性应从35岁起开展乳腺机会性筛查，高危人群可将筛查起始年龄提前至25—30岁1。医院计划于10月29日举办乳腺关爱月公益义诊，将提供30个免费乳腺钼靶名额，仅限40周岁及以上女性参加1。
A 37-year-old unmarried patient with multifocal ductal carcinoma in situ underwent successful endoscopic total mastectomy combined with immediate breast reconstruction at Peking University Shenzhen Hospital's Department of Breast and Thyroid Surgery 1. The surgical team preserved the patient's breast skin and nipple-areola complex while placing an implant through an axillary incision to restore breast contour, achieving both complete tumor removal and aesthetic preservation 1.
The case highlights the growing incidence of breast cancer among younger women in China. The National Cancer Center projects approximately 420,000 new breast cancer cases annually in 2025 1. Chinese patients are diagnosed at a median age of 47, roughly a decade earlier than their counterparts in Europe and North America, with patients under 40 comprising approximately 20 percent of cases 1. Early-stage breast cancer demonstrates a five-year survival rate exceeding 90 percent 1.
Medical experts recommend that women begin opportunistic breast screening at age 35, with high-risk populations potentially starting as early as ages 25 to 30 1. Peking University Shenzhen Hospital has performed hundreds of endoscopic breast reconstruction procedures since 2020 1. The hospital is offering 30 complimentary mammography slots during a breast health awareness event on October 29, limited to women aged 40 and above 1.
