A malignant tumor derived principally from connective tissue is known as?

A malignant tumor that originates predominantly from connective tissue is known as a sarcoma. Connective tissue includes various tissues such as bone, cartilage, fat, and muscle, and when cancer arises from these tissues, it is classified as a sarcoma. These tumors are characterized by rapid growth and the potential to metastasize, posing a serious health risk.

In contrast, melanoma refers to a type of cancer that primarily develops from melanocytes, the cells responsible for producing pigment in the skin. Carcinomas are malignant tumors that originate from epithelial cells, which line the surfaces of organs and structures in the body. Adenomas, on the other hand, are benign tumors formed from glandular tissue and do not fall under the classification of malignant tumors. Understanding the classification of tumors is crucial for diagnosis and treatment, as it helps determine the nature and behavior of the tumor.
