The increasing importance of photonics in everyday life is a fact. The field of biomedicine is not an exception, and there are a lot of growing optical applications that try to deal with some health problems. An adequate knowledge of these complex interactions is fundamental in medical praxis, where the difference between treatment and disorder can be very slight. In this work, the distribution of laser radiation and thermal effects associated on biological tissue are exposed. Light distribution inside is studied and shown as a function of tissue composition and geometrical factors. Absorption and scattering are taken into account in a random Monte Carlo model, in such a way that the approximate behavior of photons is obtained. Thermal parameters are considered in order to allow for spatial-temporal thermal distributions by means of a bio-heat differential equation.
