3 results about "Benign tumor" patented technology

A benign tumor is a mass of cells (tumor) that lacks the ability to invade neighboring tissue (spread throughout the body) or metastasize. However, they can sometimes be quite large. When removed, benign tumors usually do not grow back, whereas malignant tumors sometimes do. Unlike most benign tumors elsewhere in the body, benign brain tumors can be life threatening. Benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated (cells have normal features). They are typically surrounded by an outer surface (fibrous sheath of connective tissue) or remain with the epithelium. Common examples of benign tumors include moles and uterine fibroids.
