What is Carcinoma?
Carcinoma is a classification of cancer. Cancerous tumors are classified according to the type of cell the tumor originated from. Carcinoma originates in cells that mature into the tissues and muscles that line the surface of the body or body cavities. Carcinomas can be diagnosed through biopsy and subsequent examination of the cells using a microscope to determine the development of the tumor. Carcinoma, as a malignant tumor, has the characteristic of spreading to non-adjacent regions of the body. This process is called metastasis. Carcinoma particularly metastasizes within the lymph nodes and blood to other areas of the body.
