المستخلص: Breast cancer is one of the most common malignancies in women. In this thesis we employ fourth techniques for diagnosing the breast cancer early; UV - visible spectroscopy, Fourier Transform InfraRed (FTIR - ATR) technique, Atomic Absorption Spectrophotometer (AAS) and Solid - State Nuclear Track detectors (SSNTDs) (CR - 39NTD),was took blood samples to females whom newly diagnosis breast cancer ,control groups and females whom took chemotherapy at aged (33 - 74) years in the Middle Euphrates Center Cancer of Al Najaf province : UV - visible spectroscopy technique : we have found fourth types of bands in the spectra of this technique for female of breast cancer ,female who take chemotherapy and healthy subjects . First, second and third band regions cover the ultraviolet behavior of proteins but fourth band does not show absorbance of proteins, we noted appeared and disappeared some bands also increased the absorbance in patients which are represented early an evidence for diagnosing breast cancer.Fourier Transform Infrared (FTIR - ATR) technique : By employed this technique we found the absorbance of patients with new breast cancer larger than the absorbance of health subjects was found high statistically significant for wavenumber(ʋ) cm - 1 (1246.1 - 1241.4cm - 1) , (1536.4 - 1530.3cm - 1), and ( 3297.3 - 3277.0cm - 1) where was p - value < 0.05 while (698.6 - 667.8 cm - 1) and (2937.8 - 2925.5 cm - 1) was non - significant statistically p - value was larger than 0.05 also getting shift in wavenumber between two cases.Atomic Absorption Spectrophotometer (AAS) technique : by using itcalculated the levels of the (trace elements) metal ions(Cu ,Zn ,Fe ,Mnand Ni) has a potential role in early detection and monitoring of breastcancer where we found high increased in concentration of Iron in patientsand less in copper compared with health while high decreased inconcentration in Zinc, Manganese and Nickel in patients compared withhealth .Solid - State Nuclear Track detectors (SSNTDs) technique : we calculated by using it the mean of concentration of radon and activity of radon for females of control groups , newly diagnosis breast cancer and females whom took chemotherapy which was ARn (Bq) health group(0.097895) > ARn (Bq) new case(0.079873) > ARn (Bq) take chemotherapy(0.036443) > . We have found the Levene's Test (F) was Significant for the comparative between normal case and the case of take chemotherapy( .012) less than 0.05, the Levene's Test (F) was higher significant for the comparative between new case of breast cancer and the case who take chemotherapy (.001) much less than 0.05 while non - significant statistically between normal and new case(.731) larger than 0.05.
