What is the name for a type of tumor that does not spread to other parts of the body?

A tumor that does not spread to other parts of the body is referred to as benign. Benign tumors are generally localized growths that do not invade surrounding tissues or metastasize to distant sites. This characteristic distinguishes them from malignant tumors, which can grow uncontrollably and spread throughout the body.

Benign tumors often grow slowly and may not pose a significant health threat, although their size and location can sometimes cause complications, depending on where they are situated in the body. Common examples of benign tumors include lipomas (fatty tumors) and uterine fibroids.

The other terms in the options signify different types of tumors or related concepts. Malignant denotes tumors that are cancerous and capable of spreading. Metastatic refers to cancer that has spread from its original site to other parts of the body. Carcinogenic pertains to substances or exposures that can lead to cancer, rather than describing a type of tumor. Hence, benign is the correct term for tumors that remain localized and do not spread.
