(Top) Displacement maps and (bottom) stress $\overline{\sigma }=\left({\sigma }_{\mathit{rr}}^s+{\sigma }_{\mathit{\theta \theta }}^s+{\sigma }_{\mathit{\phi \phi }}^s\right)/3$ for the host tissue presented over the reference configuration (right), and for the tumor presented over the final/deformed mesh configuration (left).
