OK, here is my reasoning:
I have picked the blue whale species in particular because they are the largest animals on Earth and you will see why that is relevant next:
An adult blue whale's mass is typically about 180 tons
An adult human's mass is typically about 1/12 tons
So a typical human is about 12*180 = 2160 times more in mass.
Lets call that 2000 times more.
Now, assuming that the cells of a blue whale are about the same size as that of a humans (I tried googling this to check this but got nowhere ), and that the number of body cells in a mammal’s body is about proportional to its body size, an adult blue whale should have roughly about ~2000 more cells than a adult human.
So that is 2000 times more cells that could mutate into a deadly cancer that will kill the animal. And, because it takes only one cell in the body to mutate to become a terminate strain of cancer, that means if each cell of the whale has the same probability of mutation into such a deadly strain of cancer as that of each human cell, that means there is up to a 2000 times more risk of the whale getting such a fatal cancer (actually, the maths of probability is more complicated than that and it will be at least a bit less than 2000 times the risk but, I think you get the idea ). But, if that is so, that would mean that every blue whale will almost inevitably get fatal cancer and they would have become extinct long ago as a result!
But blue whales must have evolved to become so large from a much smaller species over many millions of years of evolution thus giving plenty of time for brutal Darwinian natural selection to evolve their cells to become much more resistant to becoming such a deadly cancer simply by the more cancer-prone whales being killed off by cancer. And, assuming an average blue whale is now no more prone to cancer than an average person, that means their cells have now evolved to be roughly about 2000 times less prone per cell to becoming cancerous than that of a human cell to compensate with having 2000 times more cells that could potentially become cancerous.
Do you think this is a good theory based on valid reasoning?
If my theory is correct, there may be some value in studying how blue whale cells are much more resistant to becoming cancerous because that may eventually lead to gene therapy or some other form of genetic engineering to make us humans more resistant to cancer. So I think it may be worth someone checking out my theory.
