Awareness of environmental carcinogens and cancer risk among Jordanians

Abstract

BackgroundIn light of the existing body of scientific data, many substances are now recognized or reasonably assumed to be human carcinogens. Public knowledge about modifiable environmental carcinogens is regarded as a crucial first step in primary prevention. This study aimed to assess Jordanians' awareness of some of the recognized environmental human carcinogens and general cancer information.MethodsThis study was conducted using a cross-sectional descriptive survey based on a questionnaire completed by Jordanian participants aged 18 or above. The questions consisted of the following sections: socio-demographic characteristics, questions about the prevalent and non-prevalent cancer types in Jordan and general causes of cancer, closed-ended questions to evaluate knowledge about environmental carcinogens as well as factors that influence the development of cancer, source of knowledge about carcinogens and interest in learning about human carcinogens, and the best way for prevention of cancer.ResultsA total of 579 questionnaires were completed. Among respondents, 55.6% (n = 322) had a knowledge score ≥ 8 indicating good knowledge. However, low awareness was demonstrated regarding cancer-causing substances such as wood dust, Nitrosamines, Aflatoxins, Formaldehyde, Naphthalene, Asbestos, Benzene, and Arsenic. A significant portion of the participants failed to categorize infectious pathogens linked to cancer as variables that either cause cancer or raise the risk of developing cancer.ConclusionThis study demonstrated a good level of awareness regarding some environmental carcinogens but also highlighted the lack of knowledge about other environmental carcinogens. These findings may provide a guide for future awareness programs by health authorities.
