Figure 18

The graph (left side) and density plot (right side) of the bone mass z ( t , x ) for the spatially dependent bone model with tumor and treatment (compare to Fig. 15). System of equations (16): Treatment stops the loss of bone mass from the advance of the tumor from the right side to the left side of the spatial region Ω = [0, 1] after initiation at t _start = 600. Bone mass already lost is not recovered on the right side of Ω as treatment continues.
