A mass of cells is called a what?

Explanation:
A tumor is a mass of cells formed by abnormal tissue growth. It describes a lump that results when cells divide more than normal or in an unregulated way. This term specifically captures the idea of a “mass of cells,” which is why it’s the best choice. Cancer, while related, refers to a malignant tumor that can invade surrounding tissues and spread; not every mass is cancer. An embryo is simply an early developmental stage of an organism, not a general term for a lump of cells. Differentiation is the process by which cells become specialized in their structure and function, not a description of a tissue mass.
