Dr. Hulda Clark's new book, The Prevention of All Cancers has been published 10 years after her original book, The Cure for All Cancers. It catches us up on Dr. Clark's advancements in experimental zapping techniques including the new Food/Water Zappicator. I found that this book was very detailed, but I think that if you are a first time reader of Dr. Clark's books, it may be best to first read her book, The Cure For All Diseases as a basic foundation. Then it would be good to read Prevention for the advanced information. I like the Diseases book more because of it's simplicity, and that I believe that simple methods are more effective because more people will actually be able to follow simple methods. I have personally had three family members with various forms of cancer, and they all successfully followed the herbal parasite cleanse and basic zapping programs found in Dr. Clark's Diseases book, (and are all cancer free to this day). I don't think any of them would have gotten into making Homeographic Drops, Plate Zappping, Syncrometer Science, or any of the involved processes found in the new Prevention book. It was difficult enought just to get them to take their Black Walnut Hull herbs, and use a zapper, so anything more involved would have been a turn off to them, I just know it. An alternative health care provider would be very interested in the information found in the Prevention book, but the average person may find the information a bit overwhelming if it is the first book one reads by Hulda Clark.
