"WebIf you’re a colorectal cancer patient, you might have seen the acronyms “MSI” and “MSS” in reference to tumor testing. Colorectal cancer tumors are often referred to as having an “MSI status,” meaning they will either be MSI or MSS – they will not be both. All colorectal cancer patients should get their tumors tested and know their MSI status. " - Phenotype pmmr
