Then I'll attempt to educate you. In 1990 the world population was 5,300,000,000 people. In 2019 the world population was over 7,700,000,000. In 1990, there was 1.82 million cases of early-onset cancer. In 2019 there was 3.26 million cases. This was prior to any covid-19 shot. So, had you responded to this thread in 2019, you'd said, "it's crazy how common cancer is becoming in young people". That's a huge increase in cases however it's also a huge increase in population.

So based on that increase in population, we would have expected 2.64 million cases in 2019, rather than 3.26 million cases. Granted, maybe there were also probably more cases detected in 2019 due to improved technology. But the change was greater than expected based solely on population increase.

The only population number that matters when talking about early cancer are people young enough to get early cancer. Total population is irrelevant, only the population of young people matters. And of course if you have a population boom the increase in percentage of young people is going to be dramatically higher than the percent of total population growth.
