| Summary: | PURPOSE: Misconceptions associated with radiotherapy (RT) may affect the patient’s choice to undergo or not undergo RT. In this study, the level of awareness and perceptions about radiation and RT, as well as their impact on the use of RT, were assessed. MATERIALS AND METHODS: A cross-sectional survey was conducted in the city of Dar es Salaam, Tanzania, between November 2018 and March 2019. Stratified sampling was used to obtain a sample of 629 participants from 4 strata, including 53 patients with cancer, 129 health professionals, 127 medical and nursing students, and 320 respondents from the general public. A questionnaire with 13 items measuring awareness and 8 items measuring perceptions was used for data collection. The Kruskal-Wallis test and χ2 test were used to test association between predictor and outcome variables. Statistical analyses were performed using statistical software. RESULTS: The percentage of right responses was < 50% in all 13 awareness items. Only 16.9% of respondents were aware that RT would not reduce their lifespan. Only 34.5% of respondents had positive perceptions of RT. Awareness was higher among medical/nursing students, younger respondents, single or cohabiting respondents, and those who had attained a college or higher education. Overall, 52% would accept receiving RT if recommended as part of their treatment. Those who would accept undergoing RT were more likely to have higher awareness and a positive perception of RT. CONCLUSION: Public awareness of RT in Dar es Salaam is low, and negative perceptions prevail. Low levels of awareness and negative perceptions have a negative effect on the use of RT.
