Breast cancer screening coverage in Mexico is limited. It is necessary to configure the Mexican health system to make it capable of producing more mammograms, without neglecting quality and diagnostic opportunity.
To project the coverage of breast cancer screening programs according to the mammographs availability in the Mexican Health System.
An exploratory study was conducted correlating the number mammographs available in the Mexican Health System with women between 40 and 69 who are the target of screening programs in Mexico. The analysis consisted of calculating the coverage of breast cancer screening programs if each mammograph could perform 6336 screening mammograms per year. All the calculations were made with the information of the year 2020 as the most current data in terms of population density.
It was determined that the number of mammographs is enough to raise the offer of screening studies to ≈50% at the national level. There are even states whose coverage capacity is projected above 70%. Some of them are Mexico City, Colima, Durango, Quintana Roo, Zacatecas, Baja California Sur and Coahuila. Also, it was observed that the distribution of mammographs is not equitable in the national territory, suggesting investment both in equipment and in screening strategies for breast cancer.
Our data show that it is possible to advance in preventing breast cancer in Mexico, although the improvement of the management capacities of the Mexican Health System is required to improve both the coverage and quality of the breast cancer screening programs.
墨西哥乳腺癌筛查的覆盖率有限。有必要对墨西哥卫生系统进行配置，使其有能力进行更多的乳房X光检查，同时不忽视质量和诊断机会。
根据墨西哥卫生系统中乳房X光机的可获得情况，预测乳腺癌筛查项目的覆盖率。
进行了一项探索性研究，将墨西哥卫生系统中可用的乳房X光机数量与40至69岁的女性相关联，这些女性是墨西哥筛查项目的目标人群。分析内容包括计算如果每台乳房X光机每年能进行6336次筛查性乳房X光检查时乳腺癌筛查项目的覆盖率。所有计算均使用2020年的数据，因为这是关于人口密度方面的最新数据。
确定乳房X光机的数量足以将全国范围内的筛查检查提供率提高到约50%。甚至有些州的覆盖率预计超过70%。其中包括墨西哥城、科利马州、杜兰戈州、金塔纳罗奥州、萨卡特卡斯州、南下加利福尼亚州和科阿韦拉州。此外，还观察到乳房X光机在全国领土上的分布不均衡，这表明在设备和乳腺癌筛查策略方面都需要投资。
我们的数据表明，在墨西哥预防乳腺癌是有可能取得进展的，尽管需要提高墨西哥卫生系统的管理能力，以改善乳腺癌筛查项目的覆盖率和质量。
