Tumors do not grow exponentially forever — they slow as they outstrip their blood supply. Gompertz and logistic models both bend toward a carrying capacity, with growth fastest early on. This shape guides how treatments are timed. Educational tool, not medical advice.

Governing equation

\frac{d V}{d t} = bV ln \frac{K}{V}, b = 0.05, K = 1000

Reading this result: The Gompertz curve reaches half of its 1000-cell ceiling around day 46; growth is fastest early on and flattens as it nears carrying capacity.
