The word “tumor” refers to a swelling of a part of the body, generally without inflammation, caused by an abnormal growth of tissue, whether benign or malignant. Examples include lipomas, which are benign fatty growths, and carcinomas, a type of cancerous growth.
Understanding this term is crucial for discussing and comprehending a wide range of medical topics, from diagnosis and treatment to prevention and research. Historically, the term has evolved alongside medical knowledge, shifting from broad descriptions of swellings to more specific classifications based on cellular characteristics and behavior. This evolution highlights the ongoing importance of precise terminology in medicine.
