The US Preventative Services Task Force assessed the efficacy of breast cancer screening according to the sum of its benefits and disadvantages. We estimate that the balance of the benefits and disadvantages varies among women depending on their demographic background.
Between March 2016 and March 2017, we conducted a questionnaire survey among Japanese women who underwent population-based or opportunistic breast cancer screening at our multicenter institutions. We investigated the behavior modification among women after being informed about the benefits and disadvantages of breast cancer screening depending on their demographic background.
Out of 3032 questionnaires that were returned, 2936 (96.8%) were evaluated. The percentage of women with prior knowledge about the benefits and disadvantages of breast cancer screening before reading the leaflets that we created was 24%. However, 95% of the women were willing to undergo screening next time, despite knowing the disadvantages. Regarding overdiagnosis, the young women tended to choose usual treatment, and the elderly women tended to choose active surveillance. In response to the question on the significance of screening, the young women wished to avoid death by breast cancer; whereas, the elderly women wished to live a safe life.
Our results indicate that the information of disadvantages does not lead to a reduction in screening rates. Additionally, we found that the balance between the benefits and disadvantages of breast cancer screening varies among women depending on their demographic background, especially age.
美国预防服务工作组根据乳腺癌筛查的益处和弊端总和来评估其疗效。我们估计，女性的人口统计学背景不同，其益处和弊端的平衡也会有所不同。
我们在 2016 年 3 月至 2017 年 3 月期间，在我们的多中心机构中对接受基于人群或机会性乳腺癌筛查的日本女性进行了问卷调查。我们根据女性的人口统计学背景，调查了她们在得知乳腺癌筛查的益处和弊端后行为改变的情况。
在收到的 3032 份问卷中，有 2936 份（96.8%）得到了评估。在阅读我们制作的宣传册之前，有 24%的女性对乳腺癌筛查的益处和弊端有所了解。然而，95%的女性表示尽管知道筛查的弊端，仍愿意下次接受筛查。关于过度诊断，年轻女性倾向于选择常规治疗，而老年女性倾向于选择主动监测。对于筛查的重要性问题，年轻女性希望避免死于乳腺癌；而老年女性则希望过上安全的生活。
我们的结果表明，信息的劣势并不会导致筛查率降低。此外，我们发现乳腺癌筛查的益处和弊端的平衡会因女性的人口统计学背景而异，尤其是年龄。
