In 2006, the American Cancer Society estimated that one in eight women in the US was diagnosed with breast cancer,making the illness the second leading cause of death among women, after lung cancer.Although numerous studies have established early detection and diagnosis to be critical for successful treatment, there is currently a lack of noninvasive techniques that have sufficient sensitivity and specificity to provide reliable and consistent diagnosis of breast cancer.While magnetic resonance imaging (MRI) with contrast agents has shown higher sensitivity to detect breast cancer compared to X-ray mammography, the technique suffers from low specificity for the disease, with as many as 53-80% of breast lesions detected by MRI often turning out to be benign.
