Abstract
Non-invasive diagnosis of breast cancer came into existence after the invention of X-ray Computerized Tomography and
diagnostic measuring systems using various forms of radiation viz. magnetic resonance imaging (MRI), ultrasound imaging etc. Each of these suffers from its own drawbacks.
Optical tomography is a technique which is used to diagnose breast cancer at early stage that too non-invasively. The challenge faced in optical tomography is that light radiations used in optical tomography scatter a lot in biological tissue. Therefore, need arises to study the
behaviour of propagation of light through biological tissue. The study can be done either using Stochastic models like Monte Carlo methods or by deterministic models using Finite element methods. AN attempt has been
made to study the light propagation in biological tissue using both the methods and a comparative study has been carried out.
