Bonus link: 83% of tattoo inks contain hidden ingredients linked to cancer, organ damage: study
From the NewAtlas article at top:
Getting a tattoo, regardless of its size, increases the risk of developing lymphoma by 21%, according to a new study.
. . . Tattoos are much more common than they were a couple of decades ago. According to the Pew Research Center, 32% of US adults have one, and 22% have more than one. Now considered to be more socially acceptable, everyone – from pop stars to politicians – seems to be sporting ink.
. . . The lymphatic system is part of the immune system. It keeps body fluid levels in balance and defends against infection. There are two main types of cancer affecting the lymphatic system: non-Hodgkin lymphoma (NHL), which accounts for around 90% of all lymphomas, and Hodgkin lymphoma. There are about 40 subtypes of NHL, which differ in how fast they grow and spread. NHL is one of the most common cancers in the US and can occur at any age.
. . . Previous studies have found particles of tattoo ink – and, indeed, metal nanoparticles from the tattoo needle itself – can travel to the lymph nodes.
“We already know that when the tattoo ink is injected into the skin, the body interprets this as something foreign that should not be there and the immune system is activated,” Nielsen said. “A large part of the ink is transported away from the skin to the lymph nodes, where it is deposited.”
Nah I get all that. We’ve had this conversation before and your case is plausible.
I don’t have a firm conclusion on it, and certainly haven’t changed my language usage.
There are likely mixes of genuine and fake involved. It’s still weird, and will take a lot of working out a lot of details to come to any conclusions - the digging I was referring to.
All group study exercises are a little weird. “What makes this guy [job role]?” “Well, he [wear costume] and [know lingo] and [repeat some basic concepts], so [authoritative]”, but that same person will reject a hobbyist with heavy expertise but no costume as less authoritative. Stuff just gets weird in this area, as the practice itself is often essentially trying to define a shade of gray as black or white.
