The term “tumour” is derived from Latin and simply means “swelling”.

Water retention in the tissue can also be designated as a tumour. All tumours are not necessary malignant. In terms of cell propagation, tumours may arise from all living cell structures.

benign tumour  does not grow indefinitely or displace the surrounding tissue.

malignant tumour is characterised in that it is grows unstoppably. It not only displaces and destroys the surrounding tissues but also forms secondary tumours (metastases).
