Lymph nodes filled with tattoo ink

A study published in May 2024 compared 1,398 people ages 20 to 60 who had lymphoma with 4,193 people who did not have lymphoma but who were otherwise similar. The study found that lymphoma was 21% more common among those with tattooshttps://pubmed.ncbi.nlm.nih.gov/38827888/

A Danish twin study found that people with tattoos, especially larger tattoos...had higher rates of certain skin cancers and lymphoma. The authors suggest that tattoo ink, which can accumulate in lymph nodes and cause chronic inflammation, may contribute to cancer risk, though they note that more research is needed to confirm the relationship. https://link.springer.com/content/pdf/10.1186/s12889-025-21413-3.pdf

Research indicates that tattoo inks can contain heavy metals such as lead, cadmium, mercury, arsenic, and cobalt, which are linked to cancer, allergic reactions, and other chronic diseases. https://pmc.ncbi.nlm.nih.gov/articles/PMC12656104/
