Is an 8mm colon polyp serious?

An 8mm colon polyp is relatively serious. Polyps larger than 5mm fall into a range that requires attention, as they may carry an increased risk of malignant transformation. In particular, when a polyp reaches 8mm in size, the likelihood of malignancy further increases. However, size alone is only one factor in assessing the severity of a colon polyp; a comprehensive evaluation should also consider the polyp's morphology, growth pattern, and histopathological findings. The condition is considered more serious if the polyp is accompanied by symptoms such as bleeding, erosion, or infection, or if it exhibits irregular growth patterns. Therefore, for an 8mm colon polyp, timely medical intervention is recommended, including minimally invasive surgical treatment, to prevent further progression or malignant transformation.
