Breast Cancer Awareness Month (BCAM) has a long history of over 30 years, established in 1985 to occur every October, and the National Breast Cancer Foundation now leads the operation. There have been no studies to evaluate the impact of the BCAM on public awareness of breast cancer. We analyzed the impact of BCAM on public awareness of breast cancer in the U.S. from 2012 to 2021 using the relative search volume (RSV) of Google Trends as a surrogate. We also analyzed the impact of Lung Cancer Awareness Month (LCAM) and Prostate Cancer Awareness Month (PCAM) on public awareness of lung and prostate cancer, respectively, to see differences in their effectiveness among the health observances for the top three most common cancers in the U.S. We performed a joinpoint regression analysis to identify statistically significant time points of a change in trend. There were joinpoints around BCAM for "Breast cancer" every year from 2012 to 2021, with a significant increase in the weekly RSVs from 21.9% to 46.7%. Except for 2013 and 2015 for "Lung cancer", when significant increases in the RSV at 1.8% and 1.2% per week were observed around LCAM, no joinpoints were noted around LCAM or PCAM. These results imply that BCAM has successfully improved the public awareness of breast cancer in the U.S. compared to other representative health observances, likely due to the effective involvement of non-medical industries, influencers affected by breast cancer, and an awareness symbol.
乳腺癌防治月（BCAM）有着30多年的悠久历史，始于1985年，每年10月开展，目前由美国国家乳腺癌基金会牵头运作。此前尚无研究评估BCAM对公众乳腺癌认知的影响。我们使用谷歌趋势的相对搜索量（RSV）作为替代指标，分析了2012年至2021年BCAM对美国公众乳腺癌认知的影响。我们还分别分析了肺癌防治月（LCAM）和前列腺癌防治月（PCAM）对公众肺癌和前列腺癌认知的影响，以观察它们在美国最常见的三种癌症的健康宣传活动中的效果差异。我们进行了连接点回归分析，以确定趋势变化的统计学显著时间点。2012年至2021年期间，每年围绕BCAM的“乳腺癌”都有连接点，每周RSV显著增加，从21.9%增至46.7%。除了2013年和2015年的“肺癌”，在LCAM前后观察到RSV每周分别有1.8%和1.2%的显著增加外，在LCAM或PCAM周围未发现连接点。这些结果表明，与其他代表性的健康宣传活动相比，BCAM成功提高了美国公众对乳腺癌的认知，这可能得益于非医疗行业、受乳腺癌影响的有影响力人士的有效参与以及一个认知标志。
