Breast cancer screening recommendations

摘要

To the Editor When discussing results of mammography screening trials, Dr Marmot1 concluded that "Meta-analysis of these trials with 13 years of follow-up estimated a 20% reduction in breast cancer mortality among women invited for screening." This meta-analysis2 was based on 11 randomized controlled trials, most of them undertaken before the era of modern adjuvant systemic therapy for breast cancer.
