ETYM Icel. grôthr, grôthi. Related to Grow.
In biology, the increase in size and weight during the development of an organism. Growth is an increase in biomass (mass of organic material, excluding water) and is associated with cell division.
All organisms grow, although the rate of growth varies over a lifetime. Typically, an organism shows an S-shaped curve, in which growth is at first slow, then fast, then, toward the end of life, nonexistent. Growth may even be negative during the period before death, with decay occurring faster than cellular replacement.1. The process of an individual organism growing organically; a purely biological unfolding of events involved in an organism changing gradually from a simple to a more complex levela growth of hair.

ETYM Latin, from tumere to swell: cf. French tumeúr. Related to Tumid. Usage US
(Alternate spelling: tumour). An abnormal new mass of tissue that serves no purpose; SYN. tumour, neoplasm.
Overproduction of cells in a specific area of the body, often leading to a swelling or lump. Tumors are classified as benign or malignant (see cancer).
Benign tumors grow more slowly, do not invade surrounding tissues, do not spread to other parts of the body, and do not usually recur after removal. However, some benign tumors can be dangerous, such as in areas like the brain. The most familiar types of benign tumor are warts on the skin. In some cases, there is no sharp dividing line between benign and malignant tumors. + prikaži više
