Abstract:

Cancer is the most common of all human cancers. Some form of cancer is diagnosed in more than I million people in the United States each year. Cancer occurs when normal cells undergo a transformation during which they grow and multiply without normal controls. As the cells multiply, they form a mass called a tumor. Tumors of the cancer are often referred to as lesions. Tumors are cancerous only if they are malignant. This means that they encroach on and invade neighboring tissues because of their uncontrolled growth. Tumors may also travel to remote organs via the bloodstream or lymphatic system. This process of invading and spreading to other organs is called metastasis. Tumors overwhelm surrounding tissues by invading their space and taking the oxygen and nutrients they need to survive and function. Cancer cancers are of three major types: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. The vast majority of cancer cancers are BCCs or SCCs. While malignant, these are unlikely to spread to other parts of the body. They may be locally disfiguring if not treated early.
