Colon Cancer Survival Statistics for the U.S.

What are colon cancer survival rates like in the United States?


Updated: August 27, 2006

Colon cancer survival rates vary, but these statistics will give you a general idea of colon cancer survival rates for people who live in the U.S. The five-year survival rate represents the percentage of patients alive five years after their initial colon cancer diagnosis.

Five-Year Survival Statistics:

  • Stage 1 Colon Cancer: 93%
  • Stage 2A Colon Cancer: 85%
  • Stage 2B Colon Cancer: 72%
  • Stage 3A Colon Cancer: 83%
  • Stage 3B Colon Cancer: 64%
  • Stage 3C Colon Cancer: 44%
  • Stage 4 Colon Cancer: 8%
These colorectal cancer statistics were derived from a study published in the Journal of the National Cancer Institute. You may have noticed that the survival rate provided is higher for stage 3A colon cancer (83%) than for stage 2B colon cancer (72%). That's worth noting because survival rates generally decrease with later stage cancers. In the study, the researchers explained that the discrepancy may be due to the fact that stage 3 colon cancer patients usually receive chemotherapy but stage 2 colon cancer patients don't. Something to keep in mind.
