Malignant - Definition

Ask a question


The adjective malignant is a synonym, in medicine, of serious or dangerous. This is the exact opposite of the term benign, used to describe a condition that is not serious. Thus, a cancerous tumor which is hazardous to health, it is a malignant tumor, as opposed to a non-cancerous tumor without major consequences and is therefore benign. Some diseases are also complemented by the adjective malignant when they pose an insidious and potentially serious threat to the body. This term is also used in certain physiological measures when they become extreme, which is the case for a fever higher than 105 or 107° F, or for some figures of very high pressure associated with an organic impact, particularly on the retina.
