Maps of Colorectal Cancer in Your Area

Colorectal cancer is one of the only types of cancer that can be prevented through screening. When caught early, survival rates are as high as 91 percent, but drop to just 9 percent in the late stages.

Yet only about half of those over age 50 have been screened for colorectal cancer. For those who are uninsured the rate is much lower, some say only 20 or 30 percent.

With such low screening rates, more of those in lower socioeconomic levels and certain ethnicities are diagnosed at later stages.

In this state, according to figures from the California Cancer Registry, the percent of colorectal cancer diagnosed at a late, more deadly stage, ranges from 49 to 62 percent, a clear signal that people are not getting screened.

The California Cancer Registry produced maps that depict the variation in the percentage of late-staged colorectal cancers by Assembly and Senate districts, a dramatic illustration to our legislators of the need for increasing screening rates throughout California.
