If the correlation is proven true then that’s obviously terrible, but I’m in my mid 40s now, tattoo-less, and one of my biggest regrets is not getting a couple tattoos when I was younger. I feel like doing it now looks like a midlife crisis type thing. I always wanted one of those Thai tattoos where they manually tap tap tap the design into your skin with a mallet.

I had a similar issue, so I ended up getting a small abstract tattoo. Highly recommended.

The problem with these studies is that it is exceedingly difficult to correctly account for all the additional differences between people who do get tattoos and those who don't. Plus, if you don't find an effect, there is no paper to publish. So, the proper correction factor is not just to account for the data in this study; scientists would also need to implicitly correct for all the other (unpublished) attempts by…

I don't disagree to the gist of your post. However, in biomedical and public health research, papers are published even "if you don't find an effect", for good reasons. There could be simply very many unknown factors at the initial phase of some research topics. Researchers find or notice some things, publish them with rigorous discussions, proposed hypothesis with explicitly mentioned assumptions, etc. Other researchers build upon the existing results, add more discoveries, which can be proving or disproving, partially or wholly, etc. It often takes years of multiple teams to get a good enough understanding of a topic. This implicit collaboration is a positive feedback loop to advance the research.

The issue is that the vast majority don't read the detailed discussion in the papers and thus could get a partial thesis, which in many cases lead to incorrect conclusions. Media reports don't help, because they are essentially a simplified version. Otherwise, they can simply refers to the original papers and ask the audience to read them. Also, not many reporters have solid scientific training in the fields they report and don't understand the papers well enough. I don't blame them, since it is hardly their job. Good readers must be aware that the reports can be misleading, or biased, or simply wrong.

edit: grammar

Genetic predispositions, obesity and a lot of other factors also play a role in the risk of developing lymphoma. From the article: "we found that the risk of developing lymphoma was 21 percent higher among those who were tattooed" Let's put this number into context, because "percent of increased risk" is always something I struggle to picture" "Overall, the chance that a man will develop NHL in his lifetime is about…

It's still important if there is a connection

That's 0.5 percentage points. Would be nice to get that metric, too, alongside percentages sometimes. Here the initial likelihood is relatively high, when the likelihood is low, percentage increases can be very misleading. Particularly if the uncertainty around the increase is high.

I'm curious what confounding factors might be at play. I think tattoos have gotten more mainstream in recent decades, but I'd guess that before that it correlated with other risk factors [0]. [0] I'm not making any kind of oblique reference. I have no idea what those factors might be.

The hypothesis is that macrophages transport ink to the lymph nodes during the healing period

Is there any proof that after healing there is nothing going on

Who cares if others think it's a midlife crisis, do what makes you happy. I'm nearing 40 and still get a couple tattoos a year. I love the feeling of a new tattoo, it boosts my confidence and gives me a sense of accomplishment for sitting through the fairly painful process.

Yeah.. Do it.. i just turned 40th this year and got my first tattoo last year..

Don't allow your life to be defined by what you imagine other people will think about it..

I'm 40, I got a sleeve done this year. I've never been more thrilled to get one. Get tattoos. It's your body, if the art is meaningful to you, why hold back?

https://news.ycombinator.com/item?id=39542192 Tattoos indeed are known to cause cancer among other health complications.

Your linked evidence doesn't support what you say. There are plenty of examples of concerning ingredients turning up in tattoo inks (a recent study found many inks have unlisted and potentially harmful chemicals[1]). This is obviously not good, but it falls far short of "causing" anything in particular. It's similar to all the warnings in CA about "chemicals known to cause cancer" - unless you would also say somethin…

Injecting yourself with something that has proven cancer causing chemicals cannot be harmless if course

Earlier quoted context omitted.

Yup. John didn’t buy that classic car because he’s in a midlife crisis. He bought it because it’s been his dream car since he was 12, and, with the kids out of the house, he can finally get it without having a bad conscience. (It just costs $80k now instead of $8k back in 1972)

Unrelated, but one of the most interesting graphs I've ever seen was road deaths, by gender and age, when I was studying for my drivers license. There's a huge, like 10x spike in male deaths, specifically at 50. Turns out a lot of people hit that age, think "oh fuck I'm 50", go and buy a really powerful car, and get in a bad crash. So buy the car, but just keep the graph in mind haha.

Yeah same with motorbikes. Someone had a 125 when they were 16, hit 50 and decide to get a 1200cc superbike, then come off.

Do it. I’m early 40s, have several tattoos, and am about to get one wrist to shoulder. It’s never too late to do what you want in this regard.

Midlife crisis is a pejorative term for mortality perspective. Live your best life, you only get one, and what other people think matters very little (caveat being income source and partner(s)).
