Natural Killer cells do indeed attack cancer cells. But this is a HUGE oversimplification.
The point we are making is that all cancer requires multifactoral malfunction. The immune system, the cell proliferation mechanism, the tissue degeneration proteins, angiogenesis for nourishment... all of these go wrong for a cancer to succeed. Its a very complex and random event. However despite requiring all these systems to malfunction, cancer exist due to gene mutations occuring billions of times a day. Its the equivelant of being in the wrong place, at the wrong time, wearing the wrong clothes and saying the wrong thing. But despite the small chance.. it occurs regularly as genes are read wrongly so often. So who designed all this ? A disgusting cun* of a god? ......Nah we know how cancer came about.
Fixing the immune response by prehaps increasing NK cell efficiency does not rid the world of cancer.
You are mistaking the fact that immunity is involved with the misunderstanding that immunity is the cause and means of stopping it.
Please stop trying to asert this as I dont believe you think this. Its totally untrue.
