Webbut the true tumor growth law has f 0(v) ↓ 0. Conversely, if the true growth law has f 0 > f then the estimated growth rates will tend to increase as the tumor volume increases. This will occur if growth follows a power law, which corresponds to f 0(v) = vα−1, and we fit a power law with a value of α that is too small. 2 Tumor growth laws WebJun 12, 2003 · Tumors engineered to stop VEGF production after growth and development of a vascular network exhibit regression primarily of those vessels that lack vascular …
