[ANGLÈS] Breast cancer is the most common cancer in women. Almost 70% of all the cases detected from this kind of cancer come from developed countries. The survival rate varies between 40% in undeveloped countries to 80% in developed countries. The determinant factor which explains the big difference between the two ratios is the early detection of this disease: the later the disease is detected, the less the chance of survival. Because of this, the detection of breast cancer in the first stages is important to improve the survival rates over patients. In order to do this, the detection should be easy and effective. Microcalcifications are little deposits of calcium in the breast, indicators of cancer in first stages. The detection of microcalcifications could improve the options of survival in patients with breast cancer. This thesis is orientated to improve the detection of microcalcifications in mammographies through wavelets.
