Carcinoma cancers affect cell development in skin tissue and tissue-lined organs, such as kidneys, while sarcomas are found in bones, nerves, blood vessels and connective tissues, according to WebMD. Carcinoma triggers abnormal cell growth in some of the body's most essential organs and often spreads rapidly, so cases are frequently diagnosed. Sarcoma is very rare, and the most common form only causes approximately one out of 100 adult cancer cases.
