Surprisingly, it isn't fundamental to multicellular life! Consider the naked mole rat. In decades of study, and exposure to mutagenic compounds, there are been only one or two documented cases of cancer in naked mole rats. The reason why isn't clear, but it shows that it is possible to dramatically reduce the prevalence of cancers of all kinds. I agree cancer can't be completely gotten rid of, but the likelihood of it can be reduced by orders of magnitude, and least in theory.
