These are growths (neoplasms) which are not cancer and are called benign tumours to distinquish them from malignant tumours. Unlike cancer (malignant tumours U060 Map 418), they are made up of cells that are more similar to ordinary body cells, and they remain localised and do not spread. They are only life threatening if their position causes them to interfere with some vital function. Most benign tumours can be completely removed by surgery.
Other neoplasms (benign tumours) caused 0.3% of all deaths worldwide in 2002, an average of 24 deaths per million people per year.
