CRC has received widespread public attention in recent years.  A number of celebrities have shared their diagnoses or discussed screening with the public.  Awareness of CRC is important for three major reasons.

• Colorectal cancer is detectable by several screening modalities.

• Detection at an early stage has a substantial impact on survival.

• Risk can be modified by attention to medical history and lifestyle choices.
