Etymology
The term 'tumor' originates from the Latin word 'tumor', which means 'swelling'. The etymology can be traced back to the Proto-Indo-European root *teu-, meaning 'to swell' or 'to be swollen'. In medical contexts, the word has been used since the early 14th century to describe abnormal swellings of tissue. Over time, the understanding of tumors has evolved significantly, particularly with advances in medical research and techniques. Today, tumors are classified not only based on their physical characteristics but also on their biological behavior, leading to distinctions such as benign and malignant tumors. The study of tumors is a cornerstone in oncology, the branch of medicine dedicated to cancer treatment and research.
