Biomarkers and tumor testing

In the context of colorectal cancer, biomarkers are typically proteins or molecules released by a tumor, or proteins or molecules that are part of a body’s response to the presence of cancer. They can be found in blood, other bodily fluids, or tissues.

In colorectal cancer, biomarkers may include gene changes that may give rise to mutated proteins in cancer cells. Having your tumor or blood tested to identify biomarkers can provide important information about treatment options, and can be very helpful in identifying clinical trials to consider. Some trials have specific biomarkers as part of their eligibility criteria, depending on the treatment being investigated.

This can be a complicated topic but it’s important if you are looking at clinical trial options. 

To get started, here are 4 steps:

1. Watch this introductory video from our friends at the Cholangiocarcinoma Foundation:

 

2. Check out this chart

This chart from the Global Colon Cancer Association outlines currently known CRC biomarkers, who should get tested for them, and what they can tell you.
