Hyperthermia (or thermal ablation) is a cancer treatment which uses thermal energy deposited to damage and kill cancer cells in human or living body, with minimal injury to normal tissues. The treatment involves several heat transfer modes and blood flow cooling in biological processes. The objective of this chapter is to introduce bio-heat transfer models and those processes during thermal heating for tumor treatment. Heat transfer modes and blood fluid flow are interrelated during thermal heating. Blood fluid flow in thermally significant blood vessels, blood perfusion rate and heat transfer modes (conduction and convection) will be presented. Some difficulties during heating for tumor treatments will also be addressed.
