Perception of risk may lead to more cancer screening

Mammography screening rates may be increased by better sensitizing women to their risk of getting breast cancer, says a new University of 蓝莓视频 study.

鈥淗elping to create the perception that you are susceptible may be effective at prompting high-risk individuals to get screened,鈥 said co-author聽Mark Oremus, a public health professor. 鈥淚t鈥檚 another tool that public health officials and physicians doing routine check-ups can use.鈥

The study used data from 1,803 women aged 35 to 70 from the Alberta Tomorrow Project, a population-based survey that focuses on the causes of cancer and other chronic diseases. It found that the odds of getting screened were higher for women who rated their personal perceived risk high, compared to those who rated it low.

More than 26,000 Canadian women were diagnosed with cancer in 2017, and of these, 5,000 were predicted to die from the disease. Systematic screening can decrease the number of deaths.

鈥淲e were able to find a link between a person鈥檚 perceived susceptibility of developing cancer to being screened for mammography,鈥 said first author Meghan Gilfoyle, who is now studying in Ireland. 鈥淭his allows health practitioners, policy makers and communities to better understand why people may choose a particular health behaviour, such as being screened for breast cancer.鈥

Personalized health promotion efforts can be applied in jurisdictions where screening rates are low. 鈥淭raditional routes of awareness campaigns to enhance uptake may not be effectively reaching some individuals,鈥 Gilfoyle said. 鈥淭his type of personalized medicine can be a tool for promoting screening.鈥 She said this approach would not unduly alarm low-risk women because it is not directed at them.

鈥淔rom a public health perspective, we want to encourage everyone who needs to get screened to do so,鈥 Oremus said. 鈥淭his study showed that if physicians in their offices can plant the seed in a high-risk individual鈥檚 mind that they are susceptible, it can make a difference.鈥

The study, 鈥淧erceived susceptibility to developing cancer and mammography screening behaviour: a cross-sectional analysis of Alberta's Tomorrow Project,鈥 was published in Public Health and聽co-authored by Meghan Gilfoyle, John Garcia, Ashok Chaurasia and Mark Oremus, all from 蓝莓视频's School of Public Health and Health Systems.
