ASCO’s National Cancer Opinion Survey was established by the American Society of Clinical Oncology (ASCO), in collaboration with The Harris Poll, to track the U.S. public’s views on cancer research and care. As the world’s leading organization of oncology care professionals, ASCO believes it is critical to understand what the public, including patients, think of, expect, and need from the nation’s cancer care system. The poll, supported by Conquer Cancer, The ASCO Foundation, is designed to be conducted annually to measure shifts in the public’s perceptions of a range of cancer-related issues over time.

Findings released in October 2019 from the third annual National Cancer Opinion Survey reveal:

  • Only one in four adults report caring deeply about cancer prevention and incorporating risk reduction strategies into their daily lives.
  • Americans are more likely to get information about cancer prevention online than from their doctors.
  • Two-thirds of Americans are unsure about which sources to trust for information on what causes cancer.
  • There are many misconceptions among adults about what causes cancer, and only a minority are aware of lifestyle factors that increase their risk.
  • Roughly one in five young adults uses e-cigarettes daily or recreationally.

The latest survey was conducted online by The Harris Poll from July 9 to August 10, 2019, among 4,001 US adults aged 18 and over. Of these adults, 195 have or have had cancer. A broader set of survey findings will be released on October 30, 2019.
