How do sarcoma and carcinoma cancers differ

Tumor types

The name of tumors depends on the type of cell from which a tumor develops. Tumors can arise from various tissues, e.g. B. from glandular, muscle, connective or supporting tissue. Malignant tumors that develop from gland cells are called Carcinomas (Greek "karkinos" = cancer). In turn, a benign tumor that grows from gland cells is called Adenoma (Greek aden = gland). Sarcomas on the other hand are malignant tumors that develop from muscle or connective tissue (Greek "sarx" or "sarkos" = meat).

Further examples of how malignant and benign tumors are named after their tissue of origin can be found in the table below. In addition, there are tumors that originate from different cells, e.g. B. of muscle and gland cells. These tumors are called mixed tumors.

Names of benign and malignant tumors depending on their tissue of origin:
