Colorectal cancers in many cases have spread before the initial tumor is detected, based on a breakthrough new Stanford University study. The conclusion of the study finds patients who are identified to have early metastasis can potentially be guided in their treatment decisions based on the tumor detection.

Stanford Medicine News Center’s Krista Conger reports that lead researcher Christina Curtis and her colleagues found that colon cancer tumors could potentially spread to other parts of the body much earlier than previously understood.

In fact, the venerable Silicon Valley institution reveals that up to 80% of metastatic colorectal cancers are likely to have spread to distant locations in the body before the original tumor has exceeded the size of a poppy seed, according to the study posted here.
