Everyone is born with cancer cells but the p53 gen

Everyone is born with cancer cells but the p53 gene keeps cancer cells from becoming tumors. When the p53 gene becomes mutated then the human body no longer has the healthy p53 to keep cancer from forming tumors. If Kevetrin rejuvenates p53 to heathy genes then in my mind if the cancer studies show this is what happens then how can Kevetrin not be a cure? I'm sure that most of you know a lot more than me. That's why I like this Board, I'm here to learn. Thank you for allowing me to do this.
