Voltage to be A cure to Cancer, Could it be ?

Nowadays many people around the world died caused by cancer. Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread to other parts of the body. Though there were many treatments and therapys were now solution to this disease but not all of this is 100% accurate , that we will not mind if we will have this disease for as long as we have a money to afford the treatment and therapys but this disease was sometimes called " traitor disease ", why ? because you will not notice that you have this kind of disease.

Then I came up with this theoretical solution I guess (if ever there's no one have already the same idea as I have thought or implemented it) , why not used " VOLTAGE " to kill cancer cells that are spreading throughout our body ?

VOLTAGE - also called electromotive force(emf) is a pressure from an electrical circuit's power source ... The key word is " pressure " why not apply a certain amount of voltage to a specific part of our body that is affected by cancer cells ? it may be possible right ? but the problem is, we should have to used advance technologies to undergo this risk treatment because we are dealing with a human's body that is very much sensitive.

The technology that I talked about is "NANOTECH" , maybe through this advanced technology , this treatment will be possible because NANOTECH as what I have known was today's leading and advanced technology.
