Colorectal cancer (CRC) screening is underutilized due to low knowledge and common misperceptions. Addressing barriers and improving public awareness can increase CRC screening rates.
Area of Science:
- Public Health
- Preventive Medicine
- Health Communication
Background:
- Colorectal cancer (CRC) screening rates remain suboptimal, leading to preventable morbidity and mortality.
- Limited understanding exists regarding the underutilization of CRC screening technologies and low adherence rates.
Purpose of the Study:
- To assess knowledge about CRC among adults.
- To investigate perceived risk, barriers, and facilitators for CRC screening.
- To examine experiences and intentions regarding fecal occult blood testing and flexible sigmoidoscopy.
Main Methods:
- Semistructured focus group interviews were conducted.
- Data were analyzed from a nonrepresentative sample of 39 community-dwelling adults aged 50-64 and 65+.
Main Results:
- Participants demonstrated low knowledge and common misperceptions about CRC.
- Provider practices contributed to low perceived risk among individuals.
- Numerous remediable barriers to CRC screening were identified.
Conclusions:
- Public awareness campaigns and addressing service-related factors are crucial for improving CRC screening utilization.
- Further research and interventions are needed to overcome barriers and enhance screening adherence.
