A 2022 study claims that a combination of vitamin D supplements, Omega-3 fatty acid supplements, and (mild/moderate) exercise reduces cancer risk by 60% or so for older adults, but the same factors apply to young people as well.

I could easily believe that lack of sunlight (vitamin D) and exercise accounts for almost all of the observed increase.

Screen-associated pastimes strike again!

It seems that many (maybe most) cancers are kicked off by inflammation, or otherwise stressed tissues, after the conditions are just right (genetics, carcinogen, or otherwise damaged dna). Cells that are damaged enough to spread as cancer can avoid getting replicated for years or even never without a trigger. So, it could be that we aren't more exposed to carcinogens, but more frequently encounter the conditions that make the damaged cells start spreading. So, vitamin-D and Omega-3 could indeed help in that regard, and some other cause of chronic inflammation could be responsible for the upward trend.

> lack of sunlight

Might be actually too much if the increase is caused by skin cancers.

If you read the article, you’ll find there is zero mention of skin cancer, it’s mainly concerned with GI tract, liver and kidney cancers.

Yes, you are exactly correct! Vitamin D and exercise share a common result. They both increase and maintain our body’s growth hormone production at healthy levels which is the prime driver of a healthy T cell cancer/virus killing immune system function!! Chronic growth hormone deficiency is at epidemic levels in adults and increasingly in young adults that is weakening our killer T cell immune system function and causing cancer at unprecedented levels!! Sadly, most physicians who read this will roll their eyes because they think they know it all! If they did we wouldn’t have such record levels of disease and death today!!
