New Colon Cancer Survival Rates

Or, Why I need to Stay off the Internet...
The American Joint Committee on Cancer recently revised its cancer staging system. There used to be four stages: 1, 2, 3, and 4. Now, there are seven stages: 1, 2a, 2b, 3a, 3b, 3c, and 4. A new study in the Journal of the National Cancer Institute reports colon cancer survival rates for each of these seven stages.

According to the study, entitled "Colon Cancer Survival Rates With the New American Joint Committee on Cancer Sixth Edition Staging,"
five-year survival rates for colon cancer are as follows:

-Stage 1: 93%
-Stage 2a: 85%
-Stage 2b: 72%
-Stage 3a: 83%
-Stage 3b: 64%
-Stage 3c: 44%
-Stage 4: 8%
