An identified cancer and corresponding plot of measured tumor volume as a function of mouse age. (a) A cancer (circled) in the thoracic gland from week ~10 to ~22. A tiny cancer found at week 10 developed into an invasive cancer at week 14, and the size of cancer increased dramatically after that. The displayed image field of view is 25 mm × 20 mm. (b) Plot of the tumor volume (black dots) calculated as a function of mouse age and fitted (red line) with the simple exponential tumor growth model.
