Abstract
e17512 Background: Cancer awareness month campaigns are a health promotion tool used to increase public awareness about a specific cancer, its prevention, and treatment. Cancer awareness month campaigns could be most impactful in promoting awareness of cancers for which established screening guidelines exist. Currently, the United States Preventive Task Force endorses screening the general population for colon, cervical and breast cancers. We aimed to assess the effectiveness of campaigns by identifying internet search volume and monthly cancer diagnoses. Methods: GoogleTrends was utilized to identify the relative monthly volume of search terms from 2004 to 2009 as a proxy for public awareness. Search trends for“breast cancer”, “colon cancer”, and “cervical cancer” were analyzed and an average monthly search volume index (SVI) was determined. Surveillance, Epidemiology and End Result (SEER) data was analyzed during the same time period. These data were compared using Pearson's correlation coefficient and the chi square test for seasonality. The monthly trends were compared to corresponding cancer awareness month campaigns (breast cancer-October, colon cancer-March, cervical cancer-January). Results: Internet search volume was highest for colon cancer and breast cancer in the respective cancer awareness campaign months. The frequencies of breast cancer and colon cancer diagnoseswere not significantly higher in the respective cancer awareness months. Cervical cancer search volume and cancer diagnoses did not correlate with awareness campaign months. Search volume and cancer diagnoses were not well correlated for breast cancer (r=0.089) or cervical cancer (r=0.228); however, they were significantly correlated for colon cancer (r=0.386; p-value=0.0008). Conclusions: Cancer awareness month campaigns appear to raise public awareness as estimated by internet search volume for breast cancer and colon cancer. Cervical cancer awareness month campaigns do not have the same effect. There is no significant correlation between cancer awareness campaign months and cancer diagnosis incidence for either breast cancer or cervical cancer, whereas there is a significant correlation for colon cancer.
