What is another term for a tumor?

A tumor is a term that refers to an abnormal mass of tissue that results from excessive cell growth. The more technical term for a tumor is "neoplasm," which is derived from Greek, where "neo" means new and "plasma" refers to formation or growth. Thus, a neoplasm encompasses both benign (non-cancerous) and malignant (cancerous) growths and denotes the abnormal proliferation of cells that cause the formation of a tumor.

While the term "oma" also refers to a tumor, it typically appears as a suffix in the names of specific types of tumors, such as "lipoma" (fat tissue tumor) or "melanoma" (skin tumor). It is more of a descriptor rather than a standalone term for tumor as a whole.

Sarcoplasm refers to the cytoplasm of striated muscle cells and is completely unrelated to tumors or neoplasms. A lesion is a broader term that describes any abnormal change in tissue, which includes tumors but is not synonymous with them since it can refer to inflammatory, traumatic, or other changes in tissues. Therefore, the best and most precise term for a tumor is "neoplasm."
