A carcinoma is cancer that originates in the epithelial tissue. Let's break down this definition:
Understanding Carcinoma
Carcinomas are the most common type of cancer. To understand them fully, we need to understand epithelial tissue.
-
Epithelial Tissue: This tissue type lines most of your organs, the internal passageways within your body, and your skin. Think of it as a protective covering for many parts of your body.
- Examples include the lining of your esophagus, the surface of your skin, and the lining of your lungs.
-
Carcinoma Development: When cells in this epithelial tissue become cancerous, they can grow uncontrollably and form a tumor, leading to carcinoma.
Types of Carcinomas
Because epithelial tissue is so widespread, carcinomas can occur in many parts of the body. Here are a few examples:
- Skin cancer
- Breast cancer
- Kidney cancer
- Liver cancer
- Lung cancer
- Pancreatic cancer
- Prostate cancer
- Head and neck cancers
