The highest-burden regions and cancer types were high-middle and middle SDI regions and early-onset breast cancer, TBL cancer, CRC and stomach cancer, respectively. Dietary risk factors, alcohol use and tobacco consumption were the main risk factors for top early-onset cancers in 2019.
So breast cancer because of obesity (not in this paper, see my link below), tracheal, bronchus, lung cancer because of smoking (which they mention is declining due to tobacco control measures), and stomach cancer because of high salt diets?
They also mentioned colorectal cancer being a high risk due to obesity.
The increasing prevalence of obesity in younger generations has led to a substantial increase in early-onset CRC cases.
There's also the known link between obesity and breast cancer.
So all in all, your weight and your diet are the big risk factors.
This increase probably isn't surprising at all!
What I'd like is a menu of delicious recipes that are also low in all the delicious things that are killing us. I know I shouldn't eat bacon or red meat or animal fats or processed foods or foods high in salt or too many carbs or foods high in saturated fat, but what am I supposed to eat! I want to eat yummy food! Doing that without fat, salt, crispy bits, or acidic foods giving me syomach ulcers leaves me with nothing from Salt Fat Acid Heat!
