The new research in cancer treatment is to find a way to target cancer stem cells which are the cells that drive the cancer growth. Chemotherapy up to date has only had success in killing the non-stem cell cancer cells. These are the cancer cells that grow from the core stem cancer cells. The problem is when you use toxic chemotherapy to try to kill the cancer cells all you accomplish is a temporary killing of the outer layer of non-stem cancer cells. The true source of the cancer proliferation is the cancer stem cells which are not killed with chemotherapy.
A dry, hacking, cough is another story. This is one we do want to stop. It can be caused by allergies, dry air, a random tickle at the back of your throat that won’t go away, the aftermath of a cold, being in a dusty environment, etc. etc. For these we turn to demulcents, ingredients that soothe irritated mucous membranes and remove the irritant triggering the cough. Studies conducted in 2004 found that the main ingredients in cough syrup (dextromethorphan and diphenhydramine) have the same effectiveness in treating coughs as a placebo ingredient. Instead of turning to chemical solutions for every minor ailment, try some home remedies instead. They are not only better for you, but they taste a whole lot better than most cough syrup too!
On the other hand, pathological ketoacidosis is a consequence of other disease conditions such as poorly managed type one diabetes. In this case, the level of ketones will be in the range of 15 to 25 mM. These extremely high levels of ketones can be a serious health problem. The ketogenic diet does not produce this level of ketones. For a thorough discussion of the scientific literature related to the use of the ketogenic diet in cancer treatment I recommend the treatise on the subject by Dr. Thomas N. Seyfried, Cancer as a Metabolic Disease. 
Health Quarter Ministries in Colorado Springs is run by Dr. David Frahm, who wrote the book "A Cancer Battle Plan". They offer a 10 day detox retreat, as they believe proper nutrition heals the body at the cellular level, but before nutritional changes can be effective, detoxing the system must take place. There is a very strong "spiritual" aspect to their program. For information, go to http://www.healthquarters.org/, call (719) 593-8694, or fax (719) 531-7884.
Multiple scientific reports suggest that Iscador augments the immune response. Iscador has been shown to increase natural-killer cell function helping the body’s own surveillance system in attacking unwanted cancer cells. It also stimulates antibodies to cancer cells which helps recognize the cancer cells as foreign in order to destroy these cells.
