I’m new to this idea and NOT educated in biology let alone oncology, but here’s a meta study that suggests early exposure to famine is associated with increased cancer risks, if tenuously: https://www.sciencedirect.com/science/article/pii/S1279770723002579#:~:text=A%20remarkably%20elevated%20risk%20for,CI%3A%201.13–1.42 https://www.sciencedirect.com/science/article/pii/S127977072...). Of course looking at the effect of famine on an adult populations would do more to investigate your hypothesis than the effect on developing children. But famine seems a bit extreme, no? Aren’t there also regional studies that show regional dietary/nutritional factors that correlate with lower cancer rates?
