  • Tattoos carry risks such as bacterial infections and allergic reactions; about 11 per cent of complications are infections and 37 per cent are allergies, often linked to ink or aftercare products.
  • Some tattoo inks contain unlisted ingredients, and researchers are studying possible links between tattoos and cancer, especially lymphoma, though evidence is not conclusive.
  • To reduce risks, ensure clean skin, avoid red pigments if allergic, keep tattoos protected, and choose experienced tattoo artists for safer procedures and aftercare.

Some researchers are also studying whether tattoos can cause longer-term complications, like cancer.
