Which of the following terms describes a tumor?

The term "neoplasm" specifically refers to an abnormal growth of tissue, which can form a tumor. Neoplasms can be benign or malignant; that is, they can be non-cancerous or cancerous. The key aspect of a neoplasm is its uncontrolled cellular proliferation, which distinguishes it from normal cells that typically grow and divide in a regulated manner.

While benign growths can technically describe a type of neoplasm, the term "benign growth" is narrower in scope and does not encompass the entire range of neoplasms, including those that are malignant. Apoptotic cells are in the process of programmed cell death, which is not directly related to tumor formation. Normal cells do not have the uncontrolled proliferation characteristic of tumors. Therefore, "neoplasm" is the most accurate and encompassing term for describing a tumor.
