Neoplasm encompasses which types of tumors?

Neoplasm refers to an abnormal mass of tissue that results from uncontrolled cell division. This term encompasses a variety of tumor types, which can be classified as either benign or malignant. Benign tumors are non-cancerous growths that do not invade surrounding tissues or metastasize, while malignant tumors are cancerous and have the potential to invade local tissues and spread to other parts of the body. By defining neoplasm in this way, it becomes clear that the correct answer is that it includes both benign and malignant tumors, highlighting the broad nature of the term in medical terminology. This distinction is crucial for understanding how tumors can behave and the implications for treatment and prognosis.
