The plural form of carcinosarcoma, which is a rare tumor containing both cancerous cells and connective tissue cancer cells growing together.
From Greek 'karkinos' (crab, cancer) + 'sarx' (flesh) + '-oma' (tumor). The term combines the roots for cancer and fleshy tumors, coined in medical terminology to describe this hybrid malignant growth.
This word is a medical term so specific that even many doctors rarely use it—it describes a tumor so rare that each case is practically a medical mystery, and doctors have to combine words from ancient Greek just to name what they're seeing.
