Localized thermal effect on tissue

Localized thermal effect on tissue refers to the application of controlled heat to specific tissue regions to induce biological responses. This effect underlies local hyperthermia therapy and physical ablation techniques (such as radiofrequency, ultrasound, photothermal therapy), frequently used in oncology to ablate tumors. The precise thermal dose is crucial: cytotoxic temperatures (~41–45°C) maintained for defined periods cause cell death by protein denaturation, membrane disruption, and interruption of cellular processes[1][2][5]. The effect depends on tissue characteristics, heating modality, and local blood flow, which can spare adjacent healthy tissues and enhance selectivity[1][2][4][5]. This is not a molecular target but rather a therapeutic modality based on physical law and tissue response.
