In Cancer, Disease of Civilization (1960), Wilhjalmur Stefansson mentions a few cultures besides the Inuit in which large-scale searches never turned up cancer. Dr. Albert Schweitzer examined over 10,000 traditionally-living natives in Gabon (West Africa) in 1913 and did not find cancer. Later, it became common in the same population as they began "living more and more after the manner of the whites."
In Cancer, its Nature, Cause and Cure (1957), Dr. Alexander Berglas describes the search for cancer among natives in Brazil and Ecuador by Dr. Eugene Payne. He examined approximately 60,000 people over 25 years and found no evidence of cancer.
Sir Robert McCarrison conducted a seven year medical survey among the Hunza, in what is now Northern Pakistan. Among 11,000 people, he did not find a single case of cancer. Their diet consisted of soaked and sprouted grains and beans, fruit, vegetables, grass-fed dairy and a small amount of meat (including organs of course).
I no longer think of cancer as an inevitable risk of getting old, but as another facet of the disease of civilization.
