What type of tumor is identified as a lipoma?

1. Malignant connective tissue tumor

2. Benign epithelial tissue tumor

3. Benign fatty tumor

4. Malignant fatty tumor

The correct answer is: Benign fatty tumor

A lipoma is classified as a benign fatty tumor. It is composed of adipose (fat) tissue and typically appears as a soft, movable lump under the skin. These tumors grow slowly and are generally painless, which distinguishes them from malignant tumors that typically exhibit aggressive behavior, invade surrounding tissues, or metastasize to other parts of the body. The benign nature of a lipoma means that it is not cancerous and usually does not pose a serious health risk. Although they can be removed for cosmetic reasons or if they cause discomfort, lipomas typically require no treatment. Understanding this classification is essential because it guides both the diagnostic approach and management of patients presenting with such tumors. Knowledge of the benign versus malignant characteristics of tumors helps in determining appropriate therapies and the prognosis for patients.
