Knowledge, attitudes, and risk perception in relation to second primary cancer (SPC) screening and their impact on screening practices in cancer survivors are largely unknown.


A total of 326 cancer survivors who had completed primary treatment for cancer >1 year previously were recruited from 6 oncology care outpatient clinics in the Republic of Korea. Survivors' knowledge, attitudes, perceived risk, and screening practices were assessed along with sociodemographic, behavioral, and clinical characteristics. Multivariate logistic regression was used to examine behavioral factors associated with the completion of all appropriate SPC screening according to national guidelines.


Approximately 37.7% of survivors had undergone all appropriate SPC screening tests. Survivors were found to have a high perceived risk of SPC, high perceived benefits of screening, and positive attitudes toward cancer screening. However, they had limited knowledge regarding SPC screening tests and few had received a recommendation from a physician to undergo SPC screening. Although there was no association found between perceived risk and positive attitudes with screening behavior, higher knowledge was noted to be significantly associated with the completion of all appropriate SPC screening (adjusted odds ratio, 1.81; 95% confidence interval, 1.03-3.33).


In the current study, cancer survivors were found to have limited knowledge regarding second cancer screening tests, which may have resulted in lower rates of completion of screening practices in this population.
