Cancer is basically your cells that have became rogue when they were damaged or mutated, but instead of committing suicide like most cells do, they instead continued to replicate their new modified coding of DNA which is now replicating at a high rate creating tumors. The immune system doesn't do anything because it sees it as just another part of your body.
That is why cancer is so hard to treat, you're trying to kill an cluster of human tissue, but doing so requires you to nearly kill the human with the disease there is no true cure for it, just lots treatments and luck.

It is my belief that cancer used to be a beneficial sell an emergency high-speed rebuilding body so which mutated and become a cancer so instead of a repair so that's why the body can't kill it because it was made to heal the body

Silly. Infections of all kinds have killed millions and the immune system can't do anything.

Because that part of the immune system is switched off and don't recognize the cells as abnormal..

Your immune system is good at killing foriegn cells.
Cancer are your own cells behaving badly.
The immune system has no effect on cancer cells.
