Shit tattoos

On a serious note:

The study shows an increased risk of Malignant Lymphoma in those with tattoos
I have lymphoma, they found it when I was being scanned after my accident, it's buried deep in my chest, so inoperable, but they're tiny and appear to not be growing, I had my chest scan in March and another year without any growth. So all in all good news.
Funny thing is I do have tattoos, four, all of which I've had for at least 40 years or more.
Im not a tattoo lover at all but I'd imagine like most stuff we mess with it has to increase risk of something changing in our body's... It seems pretty much everything is bad for us 🤷‍♂️
I read an article about this (so personally no idea..!) but the general thrust of the article was that you body spends a lifetime trying to reject the ink, and that it can trigger auto-imune issues as the body's defence system goes into overdrive.
