Definition:

Cancer refers to a collection of diseases related to abnormal and uncontrolled cell growth. This growth may result in tumours, which can be benign or malignant (cancerous). Malignant tumors may attack other body tissues and/or spread throughout the body (metastatis). Cancer can involve any tissue of the body and can have many different forms in each body area. Most cancers are named for the type of cell or organ in which they start.
