At what age is CRC screening recommended for average-risk patients? What are the preferred testing modalities for CRC screening?
CRC screening should be offered to average-risk (asymptomatic) individuals beginning at the age of 50. It is recommended that blacks should start CRC screening at the age of 45. There is growing evidence that heavy cigarette smoking and obesity may be linked to an increased risk of CRC and to the development of CRC at an earlier age; however, there are no formal recommendations for earlier screening. The risks and benefits of each CRC screening method must be discussed between the physician and the individual patient.
