doubling time

the time it takes for the number of cells in a neoplasm to double, with shorter doubling times implying more rapid growth.

Experimental biology The time necessary for a zygote or cells in culture to increase two-fold; the doubling time is usually longer than the average generation time of the individual cells of the population as there are growth constraints on the population—e.g., nutritional, senescence, death
Oncology A parameter used to determine tumour aggressiveness, which serves to prognosticate, measure therapeutic success, and quantify tumour kinetics and growth rate
