What is cancer?

For many reasons cell division can become unregulated. This leads to the formation of a mass of cells called a tumour which cannot perform their normal function – they are said to be undifferentiated. In some cases, cells from a tumour can spread to other parts of the body and form tumours elsewhere. The group of diseases involving spreading of tumour cells are collectively called cancer.
