Malignant Neoplasms
Malignant neoplasms (pronunciation: /məˈlɪɡnənt ˈniːəˌplæzəm/), also known as Cancer, are a group of diseases characterized by uncontrolled growth and spread of abnormal cells. The term "malignant" refers to the harmful, aggressive nature of these neoplasms, distinguishing them from benign neoplasms, which are non-invasive and non-spreading.
Etymology
The term "malignant neoplasms" is derived from the Latin word "malignus" meaning "evil" or "harmful", and the Greek word "neoplasma" meaning "new formation". It was first used in the medical literature in the 19th century.
