Colorectal Cancer—The Worst Enemy Is the One We Do Not Know

Background: Colorectal cancer is one of the most common cancers in humans. It is the third most frequently diagnosed malignant neoplasm and is the second highest cause of cancer mortality in the world. Every year, more and more people die of colorectal cancer because the diagnosis is conducted too late. This shows how important a role screening tests and the awareness of the population about the symptoms play in this aspect. This article aimed to determine the knowledge of the Polish population about morbidity, symptoms, prevention, and subjective feelings about the level of availability of knowledge about colorectal cancer. Methods: In 2020, a study was conducted using an online questionnaire assessing the awareness of the Polish population about colorectal cancer. A self-authored questionnaire including questions about socio-demographic characteristics, and 18 questions related to substantive issues, was used. A research group was selected ( n = 633). The substantive part of the questionnaire included questions examining the respondents’ knowledge about morbidity, symptoms, prevention, and subjective feelings about the level of availability of knowledge about colorectal cancer. Results: The respondents’ awareness level was influenced by demographic factors, such as gender: ( p < 0.05) and age ( p < 0.05) and social factors, such as: level of education ( p < 0.05) or professional situation ( p < 0.05). Compared to thematic articles from other countries, the research group was divided into smaller subgroups due to the abovementioned factors, due to which it was possible to stratify and analyze the significance of differences between them.
