Cancer consists of over 100 different diseases. Cancer can be generally defined as any malignant growth or tumor caused by abnormal and uncontrolled cell division. Normal body cells grow and divide in a controlled and orderly manner. When cancer invades the body, the abnormal cells grow at uncontrollable rates causing the formation of a mass of tissue or tumor. There are two different types of tumors, benign and malignant.
Benign tumors are made up of abnormal cells but they are not cancerous. Benign tumors are most often removed with surgery and usually do not recur. The cells in benign tumors do not move to other parts of the body or invade other tissues.

Malignant tumors, on the other hand, are made of cancerous cells. They will start out localized in a specific organ of the body, but if not treated, will eventually spread to other parts of the body. Malignant cells will break away from the original site and spread or metastasize through the blood stream which will cause the growth of tumors in other parts of the body.
