You age inevitably, because your genetic code will degrade over time, increasing the chances for malignacy. If you can reverse that in each of the 10^16 cells in your body, you will stop ageing.
I think the current understanding of the relationship between aging and cancer is a bit nuanced than this; e.g. immune system distinction is thought to play a major role in failing to eliminate precancerous cells.
