Definition: A neoplasm is an abnormal growth of tissue caused by the rapid division of cells that have experienced some type of genetic transformation or mutation into sets of cells with identical genetic make-up (mitosis).

These rogue cells, called neoplastic cells, do not behave and are not controlled like normal cells. They live longer and divide faster. These growths can be pre-malignant, malignant or benign.
