Almost in all diseases the blood undergoes major changes in chemical and biochemical properties. The study of blood by spectroscopic techniques can be used not only for understanding the biological nature of the disease, but also for the diagnosis of the breast cancer .In the present work, Fourier Transform InfraRed (FTIR-ATR) technique is employed to study the spectral differences between a healthy serum and that affected with new breast cancer .we found the absorbance of patients with new breast cancer larger than the absorbance of health human. الدم هو الوسط الدائري الرئيسي في الجسم البشري , يشارك في كل نشاط وظيفي استنادا الى
