What is Carcinoma?
The term carcinoma refers to a category of cancer that begins in the epithelial cells, which are the cells that line the body’s surfaces and organs. Carcinomas are characterized by their ability to invade surrounding tissues and spread to other parts of the body, a process known as metastasis.
Definition and Medical Classification
Carcinoma is defined as a malignant neoplasm that arises from epithelial cells. The medical classification of carcinoma is based on the type of epithelial cell from which it originates. For instance, carcinomas can be squamous cell carcinomas, which arise from squamous cells, or adenocarcinomas, which originate from glandular epithelial cells.
The classification of carcinoma is crucial for determining the prognosis and treatment plan. Carcinomas are typically classified using the TNM staging system, which considers the size of the tumor (T), the involvement of lymph nodes (N), and the presence of metastasis (M).
How Carcinoma Differs from Other Cancer Types
Carcinoma differs from other types of cancer, such as sarcomas and leukemias, in its origin. While sarcomas arise from connective tissue and leukemias from blood cells, carcinomas originate from epithelial cells. This distinction is important because the origin of the cancer influences its behavior, symptoms, and response to treatment.
Some key characteristics that distinguish carcinomas include their potential to invade surrounding tissues and metastasize to distant sites. Common types of carcinoma include basal cell carcinoma, squamous cell carcinoma, and adenocarcinoma, each with distinct features and prognoses.
