有大一女生确诊乳腺癌，专家呼吁筛查年龄前移

Core Insights - The five-year survival rate for breast cancer patients can reach nearly 90% if detected early, while the rate drops to less than 30% for late-stage patients [8] Group 1: Breast Cancer Statistics and Trends - The five-year survival rate for breast cancer in China has gradually increased, exceeding 60% recently, but the early diagnosis rate still lags behind developed countries due to insufficient screening precision [2][3] - The incidence of breast cancer among women in China is rising, particularly in the age groups of 30 and below, and 35 to 45 years old [3][4] - Over 20% of breast cancer patients are diagnosed at late stages (III-IV) [4] Group 2: Screening and Diagnosis - The "Two Cancers" screening program (breast and cervical cancer) is included in basic public health services for women aged 35-64, but awareness and participation in screening among younger women are still low [2][5] - Current screening methods, including breast ultrasound and mammography, have shown high detection rates, with early detection rates in underdeveloped regions reaching 71% [4] - The precision of screening needs improvement, especially for younger women who may not prioritize regular check-ups [5] Group 3: Technological Innovations - Advances in imaging technology and the integration of AI in diagnostic processes are enhancing the accuracy of early breast cancer screenings [6][7] - Genetic testing and AI risk assessment technologies are becoming crucial for high-risk populations, particularly those with mutations in BRCA1 and BRCA2 genes [7] Group 4: Clinical Benefits of Early Detection - Early detection of breast cancer significantly improves clinical outcomes and societal benefits, with a stark contrast in survival rates between early and late-stage diagnoses [8]
