The two most successful cancer therapies, radiation therapy and some forms of chemotherapy, work by oxidizing molecules. Oxidation therapy could be implemented with cathodic cell technology and if you consider a number of factors oxidation could be focused on cancer, and other diseases, without damaging other vulnerable parts of the body.
The first is directly targeting dense centers of disease. For instance tumors, bacterial colonies, and biofilms could easily be enervated by insulating all but the very tip of a needle which could be inserted into the target area. Connecting the needle to a cathode causes oxidation to occur at the tip of the needle. The strength of the cathode can be controlled and calibrated to a level where oxidation would not occur outside of the target area. The second consideration is that a cathodic cell could be paired with an anodic cell, where the cathode targets the centers of disease, and the anode provides surrounding tissues with antioxidants to neutralize leaky oxidative molecules. The third is the use of timing mechanisms. In modern times, all medical monitoring devices are created by electronics technology. Since our technology is also based on electronic principles it would be simple to create a binary on/off switch for both cathodes and anodes based on states of the body. With a little more work, and addition of programmable logic controllers, devices can be created to change the output of anodic/cathodic currents to suit any feasible medical situation.
By integrating insulated cathodes, anodic protection and a timing mechanism a medical device can be optimised to provide as much oxidative pressure where needed while protecting and reinforcing surrounding areas. For example, an insulated cathode tip is placed in the artery immediately upstream from the target area, such as a colorectal tumor. A signal from a blood pressure monitor would turn on the cathodic cell during the systolic phase of blood flow. This results in most of the oxidative molecules being pushed into the target area, complete coverage of the target area, and minimization of oxidative molecules downstream in healthy areas. The anode would be located downstream and can be left on at all times to regularly supply antioxidants, which have been shown to have a role in preventing cancer (1) and so there is always a population of antioxidants present when oxidants arrive from upstream.
According to James Watson, focusing on improvements to oxidation therapies, and anti cell-cycling drugs (instead of anti-cell growth) should result in cures for currently incurable cancers and higher rates of cures in others (2). Much like with AOP, cathodic cell therapeutic treatment allows for all of the same effects associated with ionizing, oxidative therapies, but with added benefits. Because the therapy is electronic in nature it allows for a much greater degree of control. That control allows for the minimization of negative side effects and healthier prognosis.
