Why are so many young people getting cancer? What the data say
Clues to a modern mystery could be lurking in information collected generations ago.
In some countries, including the United States, deaths owing to cancer are declining thanks to increased screening, decreasing rates of smoking and new treatment options. Globally, however, cancer is on the rise
As calls mount for better screening, awareness and treatments, investigators are scrambling to explain why rates are increasing. The most likely contributors — such as rising rates of obesity and early-cancer screening — do not fully account for the increase. Some are searching for answers in the gut microbiome or in the genomes of tumours themselves. But many think that the answers are still buried in studies that have tracked the lives and health of children born half a century ago. “If it had been a single smoking gun, our studies would have at least pointed to one factor,” says Sonia Kupfer, a gastroenterologist at the University of Chicago in Illinois. “But it doesn't seem to be that — it seems to be a combination of many different factors.”

No answer here, but the estimates above in the graph is more a call for more research than an actual increase. The reason that the data is until 2019 is that it takes time to get info.
Maybe in about 5+ years we will get information on the correlation between patients who have had SARS-CoV-2 infections and other diseases.
