How much of this is explained by the increase in obesity in young adults? I don’t think it’s a coincidence that the first specific cancer TFA mentions is colorectal. In the last sixty years the obesity rate has tripled with morbid obesity growing nearly ten fold.

It feels like everyday a new paper is published showing either massive levels of compounds that interfere with endocrine system in the blood. Microplastics, being the biggest one. So when I see headlines like this, "Cancer is up in young people." I can't help but sigh and think, this is expected.

I'm not sure what the right course of action here is, but do we really want to continue with a model where we continue pumping new and unknown compounds into our bodies and the ecosystem with little thought to the downstream impacts?

Some of these compounds have made our lives orders of magnitude better and yet they are wreaking havoc in our lives in ways we'll probably never understand.

Colorectal is also related to bad diets: too much processed food, not enough fiber, questionable additives, possibly microplastics, etc.

This is a bit of a surprise given how the prevalence of smoking and drinking in the younger generations is steadily declining. We also have a lot more effort put into reducing emissions from all industries. The idea that kids of the 70's chain smoking in the smog have lower cancer risk than the teetotaling youth of today is just sad.

The article touched on it a bit, but apparently obesity is a huge contributing factor and is one major area where today's children are far worse off than their historical peers.

By explained do you mean cause and effect? What is the link between the two? More cells = more that can become cancerous?

For anyone actually wanting real probabilities, a quick google on colorectal which the article mentions as the most common cancer for young men:

"For example, 1 out of every 333,000 15-to-19-year-olds developed colorectal cancer in 1999. Colorectal cancer became more common by 2020, when 1 out of every 77,000 teens"

https://www.webmd.com/colorectal-cancer/news/20240515/behind...

"The study found that colorectal cancer diagnoses in children ages 10 to 14 jumped from 0.1 cases per 100,000 in 1999 to 0.6 per 100,000 in 2020, a 500% increase. Cases among 15- to 19-year-olds jumped by more than 300%, from 0.3 per 100,000 to 1.3 cases per 100,000 people. In people ages 20 to 24, cases rose from 0.7 to 2 per 100,000 people, a 185% rise."
