The osteoclast and osteoblast populations in the presence of tumor stimulated by an initial osteoclast population elevated above the nontrivial steady state by 10 cell units. System of equations (7): The osteoclast population first increases as the osteoblast population decreases. The solutions converge to the nontrivial steady state = 5.0 and = 316.0 with damped oscillations. The parameters are α₁ = 3.0, α₂ = 4.0, β₁ = 0.2, β₂ = .02, g₁₁ = 1.1, g₂₂ = 0.0, g₁₂ = 1.0, g₂₁ = -0.5, γ_T = .005, L_T = 100, r₁₁ = .005, r₂₁ = 0.0, r₁₂ = 0.0, r₂₂ = 0.2. The initial conditions are C(0) = 15.0, B(0) = 316.0, T(0) = 1.
