Etymology
The word 'tumor' originates from the Latin verb tumēre, meaning "to swell." This root is part of a larger Proto-Indo-European family of words related to swelling or being thick. The Latin noun tumor was formed by adding the agent/state suffix -or to the verb stem, literally meaning "a swelling" or "the condition of being swollen." In its original medical usage in Latin and later in English, it described any abnormal swelling or protuberance in the body. Over time, its meaning specialized in modern medical terminology to refer specifically to a pathological swelling caused by an uncontrolled growth of cells, distinguishing it from other types of swellings like edema.
