At what point when getting tattoos does the ink go into the lymph nodes? Does is stay there indefinitely? What harm can it do?

I have a lot of tattoos from 13 years ago to even last month. I've been reading about the tattoo ink in the lymph nodes. I'm worried of what could happen to me. I also wanted to know logistically how it works. Does tattoo ink go into the lymph when being tattooed or does it leach in throughout the years? I would like to know as far as information that's out so far I understand there is a lot we don't know...
