What is the difference between sarcomas and carcinomas?

Sarcomas are cancers that develop in mesenchymal cells, or connective tissue cells—this includes bone, cartilage, fat, and blood vessels, among many other tissues. Sarcomas can be divided into two large subcategories of bone sarcomas and soft tissue sarcomas.

Meanwhile, carcinomas are cancers that develop in epithelial cells, the cells that line surfaces and tissues in the body. Some types of carcinomas include squamous cell carcinoma and adenocarcinoma.
