If your dad is that close to death you must find a pranic healer quick to build up his lifeforce and remove blocks as well as change his diet pronto. Then you have to detox the chemotherapy out of the body with Modifilan and Zeolite. Have you heard of Gersons diet? I would try it while you try other methods. Incidentally I tried the Sota Magnetic Pulser and was not impressed. I did not get rid of parasites and the silver is of such large particles I cannot use it for clients.
