The mortality of ovarian cancer has not changed in the last 30 years. Approximately 70% of the patients die of disease. The reason for this high mortality, in spite of all the new developments in medicine, is that we do not understand the disease, and therefore we approach ovarian cancer like most epithelial neoplasms. In this book Elvio G. Silva demonstrates that ovarian cancer is a hormone-related neoplasm, and the dissemination of the tumor in the peritoneum, in most cases, represents multicentric disease. In addition to the traditional cancer therapies it is necessary to correct the abnormal hormones to improve the prognosis, and probably to prevent this dreadful disease. Emphasis is also placed on understanding embryology as a necessary step to comprehend ovarian cancer. Fere Ex Nihilo presents a refreshingly new approach to tackle an age-old enemy.
