Cancer
Classification Of Cancer Types
The term "cancer" is general, in that it represents a large group of related diseases that arise from neoplasms. A neoplasm is classified by the type of tissue in which it arises and the stage to which it has progressed. Neoplasms are also called tumors. Not all tumors are cancerous. A tumor that grows in one place and does not invade surrounding tissue is called benign. In contrast, invasive tumors are called malignant. These are cancerous.
