The radiological study of the breast is vital to complete a good clinical diagnosis. In the public health of Spain screening mammograms are made every two years starting with 50 years. In other countries, such as United States, mammograms are made systematically starting within 40 years in order to increase detection rates of non-palpable tumors or lesions which are so abundant at this age. Doing routine mammograms without specific symptoms before age 40 is questionable, because it can increase the number of false positives. Obviously it is necessary to make mammograms when there is an indication of injury or tumor during clinical examination, examination that should be done on an annual basis. For young women before menopause we often add to the classic mammogram a breast ultrasound, if the gland is denser and it is possible to see better a possible injury, while other more specific tests such as MRI are only be used to confirm the diagnosis. In case of breast a lesion sign found during the testing image the biopsy is usually indicated in order to analyze the cellular component material.
