Malignancy

Malignancy (from the Latin roots mal- = "bad" and -genus = "born") is the tendency of a medical condition, especially tumors to become progressively worse and to potentially result in death. It is characterized by the properties of anaplasia, invasiveness, and metastasis. Malignant is a corresponding adjectival medical term used to describe a severe and progressively worsening disease. The term is most familiar as a description of cancer. A malignant tumor may be contrasted with a non-cancerous benign tumor in that a malignancy is not self-limited in its growth, is capable of invading into adjacent tissues, and may be capable of spreading to distant tissues (metastasizing), while a benign tumor has none of those properties. Malignant tumor is synonymous with cancer. Uses of "malignant" in oncology:

Non-oncologic disorders referred to as "malignant":
