This study investigates the efficacy and operational impact of the Can-Dial telephone service as a mechanism for disseminating cancer-related information to the public. The authors, led by Gregg S. Wilkinson, utilize empirical data collected from the service's implementation to assess how telephone-based health communication influences public knowledge and service utilization. The text provides a systematic evaluation of the facility's reach, the nature of inquiries received, and the logistical challenges inherent in managing a specialized health information hotline.

Experts in health communication identify this work as a foundational case study for evaluating telephone-based health information services. Readers frequently note the academic density of the prose and the specific focus on the administrative mechanics of public health outreach programs.
