There is no safe amount of processed meat to eat, according to new research

Sure but there are a ton of things, genetic, environmental, dietary, neurochemical, etc. that can contribute to the development of cancer. You can do literally everything right and end up in the exact same place as someone who did all the wrong things because the causes are innumerable and many are literally unavoidable.

Would I regret my choices if I got cancer after I did all the things the studies say would increase my odds? Of course I would. Would I regret my choices if did everything "right" and still got cancer? Of course I would. But that's because being in that position inherently biased you against your past. If I did all the wrong things I would regret that I indulged too much, and if I did all the right things I would regret that I never really indulged at all and enjoyed life fully. Either way you got shafted. You're damned if you do, damned if you don't.

But to me it's better to just live intentionally but without having this constant concern about every single thing I eat, drink, or breath maybe, possibly, eventually contributing to developing cancer. Like I'm not about to start smoking, I rarely drink, I try to eat enough veggies, etc. because those things have much more tangible direct consequences that I'm mindful of, and I'm not about to eat a hotdog every day mostly because I'm a really good cook and that sounds sad as fuck. But the next time I do eat a hotdog, a salami, or a Reuben sandwich, I promise you that no part of my mind is going to be worrying that it will give me cancer. Constant dread is its own form of cancer and life's too short and uncertain to live with that shit 24/7.
