And in the end...

It would be more to do with telomere lengthening than replacing body bits.

Eventually we'd all die being hit by a bus or slipping on a banana skin, but we could avoid old age.

There are several animals that don't age. Certain jellyfish as well as lobsters possibly?

Essentially telomeres are bits of our cells which shorten every time a cell replicates. This is what causes the aging process and in theory we could reverse ageing if we could find a way to significantly lengthen then.

cancer rates would increase

No i believe cancer is linked to short telomere lengths.

Anyway, i'm not a expert i was just speculating as to whether it could happen in the next 40 years.

no
cancer is cell replication that errors

Conclusion In this study population, there was a statistically significant inverse relationship between telomere length and both cancer incidence and mortality.

Telomeres are nucleoprotein complexes at the extreme ends of linear chromosomes implicit in the maintenance of chromosomal integrity. Telomeres shorten with each cell cycle and therefore reflect organism aging at a cellular level. At a critically short telomere length, cells experience replicative cell senescence. Malignant cells, in contrast, reactivate and overexpress the enzyme telomerase that lengthens telomeres and allows for plentiful divisions.

no.

radiate cells. they malfunction and cause cancer.

poison them - ditto

I would love to live forever yes. Or at least as long as i could until the world turning into a nuclear apocalypse or something.
