What happens in cancer is a disorder in this organized process. The cells that are supposed to die remain in the body, and new cells are produced without the need for them, and then these new cells proliferate non-stop and this is called the tumor. Cancer cells are characterized by the invasion of surrounding cells and tissues, and can also invade organs away from them by moving their cancer cells through blood or lymph vessels. There are more than 100 types of cancer, usually referred to as the organ or tissue from which they originate. Some cancers may be called according to their cell type, such as epithelial cell tumors.
