What is the definition of a neoplasm?

The term "neoplasm" refers specifically to an abnormal growth of tissue, which can be benign or malignant. In the context of biology and medicine, it signifies a new and uncontrolled proliferation of cells that may form a mass, commonly referred to as a tumor. This new growth results from various factors, including genetic mutations and environmental influences.

Understanding neoplasms is crucial in laboratory animal research, as they can impact the health and well-being of the animals involved in scientific studies, leading to the need for careful monitoring and management. A foundational knowledge of neoplasms aids laboratory animal technicians in interpreting the health statuses of animals and recognizing the implications of such growths on experimental outcomes.

The other options do not align with the proper definition of neoplasm. A new treatment method refers to protocols or therapies to address health conditions, a type of genetic disorder involves genetic anomalies that can lead to various diseases, and a degenerative disease refers to conditions that worsen over time, typically affecting the body’s systems or processes. Only the definition of neoplasm pertains to an actual physical growth, making it the accurate choice.
