Abstract
The essential target of the tumour's treatment is how to destroy its tissues. So, the main objective of this paper is how to invent an effective method to get enough irreversible damage by using a different type of therapy. A new thermal model of a human breast has been developed by considering three layers: skin, fat, and tumour. The internal heat source due to the chemical reactions has been considered to discuss the response time due to the perturbation based on non-classical Fourier's law with one relaxation time. A thermal incident due to laser pulse with different values of time, depth, relaxation time, and power density have been discussed. The quantity of the thermal damage has been computed to the three layers by applying the Arrhenius burn integration formula. The time, depth, relaxation time, and power density have significant effects on the three layers of the human breast.
