The 20-year survival rate is very high (over 95%) when the initial tumor size is less than 1 cm. We are faced with a major medical problem. Breast cancer is the leading cause of cancer-related deaths in women, and its incidence and prevalence have been steadily rising in recent decades. It commonly affects young women and the mothers of small children – a segment of the population that “ought not to die.” The medical problem becomes even more tragic when we consider the relatively slow growth rates of most breast carcinomas. As a rule, breast cancers are very slow-growing tumors that take years or decades to reach a size of 1 cm. Nature has actually given us a very large time window for detecting and treating breast cancer. This is quite different from pancreatic cancer or glioblastoma, where almost all patients die within a year after diagnosis. Magnetic resonance imaging (MRI) of the breast, known also as magnetic reso
