Chemotherapy or chemo for short is not always required for successful treatment either, but how to tell if someone requires it can be both an art and a science. Now, a new study provides clinicians with a technique that has already helped some stage II colon cancer patients avoid chemo, with no change to their clinical outcomes. The technique employed in this new study uses a type of DNA called circulating tumor DNA (ctDNA). This is pretty self-explanatory – it's small sections of fragmented DNA from tumors that are circulating around in the blood stream. Importantly, they are not part of a tumor cell however, just the DNA from the tumor by itself . The presence of ctDNA in the bloodstream post-surgery p
