Colon Cancer Statistics
Colon Cancer Survival RatesColon cancer survival rates indicate the percentage of people who survive the disease for a specific period of time after their diagnosis -- whether they have few symptoms, are free of disease, or are receiving treatment. Survival rates can be calculated by different methods for different purposes. The survival rates presented here are based on the relative survival rate. The relative survival rate measures the survival of cancer patients in comparison to the general population to estimate the effect of cancer. For people with colon cancer, the overall 5-year relative survival rate for 1996-2002 was 64.1 percent. The 5-year relative survival rates by race and sex were:
- 66.0 percent for white men
- 64.2 percent for white women
- 55.6 percent for black men
- 53.9 percent for black women.
Stage ImpactThe colon cancer stage plays a role in the colon cancer prognosis. Based on historical data:
- 39 percent of colon cancer cases are diagnosed while the cancer is still confined to the primary site (localized stage).
- 37 percent of colon cancer cases are diagnosed after the cancer has spread to regional lymph nodes or directly beyond the primary site.
- 19 percent of colon cancer cases are diagnosed after the cancer has already metastasized (distant stage).
- 5 percent of colon cancer cases had staging information that was unknown.
The corresponding 5-year relative survival rates were:
- 90.4 percent for localized
- 68.1 percent for regional
- 9.8 percent for distant
- 34.6 percent for unstaged.
