This series on the treatment of cancer is sponsored by the UICe. The editors and authors feel strongly that more standar­ dization in cancer therapy is needed on a worldwide basis. This, of course, is only possible if experts from all countries subscribe to a joint policy of making their treatment designs available to practising oncologists all over the world. Current Treatment of Cancer discusses all the equipment and methods now in use in cancer therapy. It covers all types of cancer, thus providing the reader with comprehensive infor­ mation on cancer management. In recent decades there has been a tremendous improve­ ment in the treatment of cancer, and there is hope for even fur­ ther success in this fight.
