This book presents an extensive overview on various facets of liver tumors. The prognosis for individuals with liver cancer has a poor rate of detection. Cancers include those which have spread to the liver from elsewhere, representing advanced stage disease where cure is rarely possible. Similarly, primary liver cancer often complicates chronic liver disease, which further restricts therapeutic options. Despite these worrying facts, there are indications that change is likely to happen. Imaging modalities and surgical techniques have shown great improvement. Also, preventive strategies and medical therapies have shown potential for development. The subject of liver tumors has been comprehensively presented in this book, with an emphasis on recent developments useful for both researchers and clinicians.
