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 puyuyuuyuyuyuyuyuyuyuyuyuyuyroperties 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:

MALIGNANT (Lat. malignus, evil-disposed, from maligenus), wicked, of a malicious or wilfully evil disposition. The word was early applied by the Protestants to the Romanists, with an allusion to the "congregation of evil doers" (Vulgate Ecclesiam malignantium) of Psalm xxvi. 5. In English history, during the Great Rebellion, the name was given to the Royalists by the Parliamentary party. In the Great Remonstrance of 1641 occur the words "the malignant partie, wherof the Archbishop (Laud) and the earl of Strafford being heads." The name throughout the period had special reference to the religious differences between the parties. In medical science, the term "malignant" is applied to a particularly virulent or dangerous form which a disease may take, or to a tumour or growth of rapid growth, extension to the lymphatic glands, and recurrence after operation.

In medicine, malignant is a clinical word that is used to describe an illness that kills a patient fast. A malignant tumor is a tumor that is able to invade nearby tissues and spread to tissues that are not nearby. Not all patients diagnosed with malignant tumors die, because of the improved treatments available. The actual prognosis depends of the type of tumor, its differentiation, and how bad the disease is. The term malignant is typically applied to neoplasms that show aggressive behaviour characterised by local invasion or distant metastasis.
