Visit my website for a full list of videos. Enjoy. https://drkevinmangum.com/youtube-pat... A tumor is said to be benign when its microscopic and gross characteristics are considered to be relatively innocent, implying that it will remain localized, it cannot spread to other sites, and is amenable to local surgical removal; the patient generally survives. It should be noted, however, that benign tumors can produce more than localized lumps, and sometimes they are responsible for serious disease, as pointed out later. Malignant tumors are collectively referred to as cancers, derived from the Latin word for crab-that is, they adhere to any part that they seize in an obstinate manner, similar to a crab's behavior. Malignant, as applied to a neoplasm, implies that the lesion can invade and destroy adjacent structures and spread to distant sites (metastasize) to cause death. Not all cancers pursue so deadly a course. Some are less aggressive and are treated successfully, but the designation malignant constitutes a red flag.
