Tattoo ink particles can spread into lymph nodes
The news come from a study that found evidence particles from tattoo ink can spread into lymph nodes – but it hasn't been proven that tattoo ink causes cancer. Researchers used samples of skin and adjacent lymph nodes taken from six donors after autopsy.
Four of the donors had tattoos and were more likely to have substances like titanium in the lymph nodes. Lymph nodes are part of the lymphatic system, which in turn is part of the immune system.
The problem is the researchers didn't include important information about whether any of the donors had cancer, or what caused their deaths. This means it's not possible to claim that the tattoo ink particles found in lymph nodes cause cancer.
