More than 90 percent of CRC occur in people age 50 and older.1
CRC has been steadily decreasing in people 50 and over, but has actually been
increasing in adults under 50. The reasons are unclear, but may reflect
increasing rates of obesity and poor diet among younger people.1
The incidence of and mortality from CRC is about 35-40 percent higher in men
compared to women.1
There are also differences in CRC incidence and mortality based on ethnicity.
For example, about 20 percent more African Americans than whites are diagnosed
with CRC each year, and approximately 45 percent more will die of the
The American Cancer Society recommends CRC screening beginning at age 50 for
those who are at average risk of the disease.1
What is the Prognosis for People with CRC?
More than 90 percent of individuals diagnosed with early stage CRC that has not
spread (metastasized) beyond the colon or the rectum survive five years; many
live much longer.1
If CRC spreads to distant organs, such as the lungs or the liver, five-year
survival declines to 12 percent.1
How is CRC Treated?
Depending on the stage of cancer and if it has spread to other organs,
treatments may be combined or administered sequentially.2
