最近，高收入国家乳腺癌死亡率的下降是由于早期发现和治疗的改善。乳腺癌是巴西妇女最常见的癌症。自2004年以来，政府建议40岁以上的妇女每年进行一次临床乳房检查，50-69岁的妇女每两年进行一次乳房X光检查。本文调查了这些准则的实施程度，根据主要地理区域和年龄组的数据，从巴西统一的国家卫生系统2010年。调查结果显示，目标人群中的全国乳房X光检查覆盖率较低（50-59岁组为32%; 60 - 69岁组为25%）。有异常放射学检查结果的妇女接受活检的百分比也很低（50-59岁为27%; 60-69岁为63%）。2010年，乳腺癌手术的数量超过了乳房X光检查发现的病例数量，但远低于乳腺癌发病的估计数量。在获得早期诊断和手术方面，各地区之间存在着显著的不平等，北部地区获得率最低，南部地区最高。
The recent reduction in breast cancer mortality in high-income countries resulted from improvements in early detection and treatment. Breast cancer is the most common cancer in Brazilian women. Since 2004, the government has recommended annual clinical breast examination for women aged >= 40 years and biannual mammograms for those aged 50-69. This article investigates the degree of implementation of these guidelines using data from the Brazilian Unified National Health System for 2010 according to major geographic region and age group. The findings showed low national mammogram coverage in the target population (32% in the 50-59-year group; 25% from 60 to 69 years). The percentage of women with abnormal radiological findings who underwent biopsy was also low (27% for 50-59 years; 63% for 60-69 years). The number of breast cancer surgeries exceeded the number of cases detected by mammography but was well below the estimated number of incident breast cancer cases in 2010. There are striking regional inequalities in access to early detection and surgery, being the lowest access in the North Region and the highest in the South Region.
