Know Your Biomarker is an awareness, education, and advocacy campaign fighting for global access to colorectal (bowel) cancer biomarker testing. Through the Know Your Biomarker program, the Global Colon Cancer Association advocates for biomarker testing for all colorectal cancer patients, because where you live should not determine whether you can survive colorectal cancer. 

In 2022, the Global Colon Cancer Association conducted an international survey among colorectal cancer patients and survivors. The aim of the survey was to shed light on patients’ involvement in their treatment plans including colorectal cancer biomarker testing. Nearly 100 respondents in 15 different countries shared their experiences.

When asked how the results of biomarker testing were discussed with them, 32% of respondents said they did not understand the treatment impact of their results, 7% reported that they were not informed of their results, and 18% of participants were unsure if biomarker testing had been performed.
