What does the term "neoplasm" refer to in cancer terminology?

The term "neoplasm" refers to an abnormal growth of tissue that can be benign or malignant. This is a fundamental concept in oncology, as neoplasms signify the processes of uncontrolled cellular growth that forms a mass. The classification into benign and malignant categories is crucial, as benign neoplasms do not invade surrounding tissues or metastasize, whereas malignant neoplasms, commonly known as cancers, can spread to other parts of the body.

Understanding neoplasms is vital for tumor registrars, as it helps categorize tumors and collect meaningful data for cancer statistics and epidemiology. This knowledge directly impacts diagnosis, treatment decisions, and patient management. Recognizing the broader definition of neoplasms beyond only malignant conditions also emphasizes the importance of monitoring and potentially treating benign tumors, particularly when they cause symptoms or have the potential to transform into malignancy over time.
