Hyperthermia is potentially an effective method for the treatment of cancer tumours. In the present manuscript, improvement in the treatment of liver cancer through electromagnetic heating is studied using high dielectric material through mathematical modelling in COMSOL Multiphysics. It is observed from the result that without increasing the power input, intensity of the temperature can be increased by changing the dielectric constant. Treatment time in ablation of the liver tumour can also be reduced. Results are obtained for total power dissipation density, heat flux, temperature distribution and fraction of necrosis tissue.
