This is just illogical. While it would be understandable to be skeptical of some specific form of anti-aging procedures or gene modifications, there is no way that science or especially anecdotal science can show why anti-aging measures would not work at all. In your specific example, even if that was the case that the same mechanism was used in cancer cells and aging - the science would of course find a way to modify that mechanism (not just speed it up or slow it down), or add another extra mechanism which would alleviate the effects of speeding it up. Body is a biological machine. When we finally understand this machine - we will be able to control such things as aging. Nature has already created animals which live for much longer than humans, which is a clear example that there are no fundamental reasons for why fighting aging could be impossible.
