Summary
First-degree relatives of colorectal cancer patients have low screening participation. Understanding their perceptions of risk and the asymptomatic nature of screening is crucial for improving uptake in colorectal cancer prevention programs.
Area of Science:
- Gastroenterology
- Oncology
- Public Health
Background:
- Colorectal cancer screening is recommended for first-degree relatives.
- Participation rates among these relatives are known to be low.
- In-depth exploration of relatives' beliefs and attitudes towards screening is lacking.
Purpose of the Study:
- To explore the beliefs and attitudes of first-degree relatives of colorectal cancer patients towards screening.
- To identify factors influencing screening participation in this high-risk group.
Main Methods:
- Conducted four focus group discussions with first-degree relatives of colorectal cancer patients.
- Audio-recorded, transcribed, and independently coded/analyzed discussion data.
- Identified key themes through qualitative analysis.
Main Results:
- Three primary themes emerged: perceived risk, understanding of screening, and screening behaviors.
- Perceived risk was influenced by family history, age, and gender.
- Limited understanding of the asymptomatic nature of screening was observed; many relatives sought screening only after developing symptoms.
Conclusions:
- Relatives' perceptions of risk and understanding of screening are critical factors affecting participation.
- Screening programs need to address misconceptions about the asymptomatic nature of colorectal cancer and screening.
- Targeted interventions are necessary to improve screening uptake among first-degree relatives.
