There are so many ways of deriving pigment for these inks. Pigment sources and brands might be regionally specific. They're not always discussed by the artist and client so testing for that might be difficult. Hopefully further studies take that into account. My lay opinion is that ink material is probably a very important factor.
Came across your video after I ready the study, I agree with the study having much less credibility due to no increased risk with a larger tattoo than a small tattoo. I am though curious your opinion on laser tattoo removal? I have read even tattoo inks classified as organic when broken down with a laser can become carcinogenic. I have also ready findings of tattoo ink staining and becoming trapped in lymph nodes after laser removal. I have been debating laser removal which is why I started looking into all of this, and the lack of current research is frightning for how large the industry is becoming.
It’s good questions that you bring up the lymph nodes do clear so far laser tattoo removal has been around since 1962, and in the last 17 years or so has become very popular and we haven’t detected any increase in malignancies in the laser tattoo removal population. Of course you’re right and then it’s becoming more and more popular and we’re gonna have to see what future data brings but the current time the feeling in the medical community is that it doesn’t pose an increased risk to medical conditions having laser tattoo removal. Under normal circumstances, your immune system is constantly chipping away at the tattoo, and you could find flex of ink in lymph nodes in people that have tattoos and of course, when you laser it, then it becomes a preponderance of ink in the lymph nodes, but so far they haven’t had any conclusive evidence that it’s harmful.
The study had a lot of problems. It was a very small sample size and they basically tried to compare people who got lymphoma who had tattoos and people who never had lymphoma and they said that the Tattoo population had 21 percent the increase in lymphoma. However, the statistical data was not what we would call significant, in the fact that having a large tattoo didn’t increase your risk any further than having a small tattoo just doesn’t make sense what if the tattoos could cause lymphoma the increase is very slight because the incidence of developing a lymphoma or about one in 45 so even if it increased it 21 percent you’re talking about a very small population. The current consensus, though is there doesn’t seem to be a genuine link between tattoos and lymphoma
