False-colour light micrograph of a malignant tumour showing cancerous cells breaking away & migrating (metastasis) from the site. A tumour arises through the transformation of a normal cell into one that escapes the usual controls of growth & differentiation. Instead the cell is large,divides rapidly & shows evidence of nuclear & chromosomal abnormality. The rate of growth,division & abnormality is greater among malignant cells than benign,but the distinguishing factor is the ability of malignant cells to invade surrounding tissue & colonize sites far distant from the original tumour (metastasis) | |
