A new study showed that tests that look for tumor DNA in the blood might help doctors personalize your cancer treatment, states Megan Johnson from U.S. News & World Report. Researchers “identified defects in the genetic code of colorectal and breast cancer samples. The defects functioned as genetic fingerprints called biomarkers that are unique to each individual’s cancer,” reports Johnson.
The research team took note of the level of cancer biomarkers in patient blood samples, and in two colorectal cancer patients, “the level of their cancer biomarkers dipped after surgery but later rose again, indicating the cancer had not been eliminated,” says Johnson. Researchers believe this new blood test could be a better way to determine if cancer has returned compared to the existing method.
