Cancer is a creepy and mysterious thing. While we tried to understand it, to get better at killing it, we discovered a biological paradox that remains unsolved to this day: large animals seem to be immune to cancer. Which doesn’t make any sense - the bigger a being, the more cancer it should have. To understand why, we first need to take a look at the nature of cancer itself.

    The solution to the paradox for anyone who cares is to make an MRI machine large enough to fit a whale inside. The next step is obvious lol you need to check the entire whale for tumors. We would have to analyze the number of tumors and the size of them. Those measurements will give us an indication of the impact hypertumors have on cancer development.
