Tattoos and your health

Tattoos can be dangerous, carrying risks like infections (bacterial, viral), allergic reactions (especially to red/white inks), scarring (keloids), and potential, though less proven, links to cancer or other systemic issues from heavy metals and chemicals in inks, requiring strict hygiene, sterile equipment, and an informed artist for safety.

Common Risks & Complications:
Infections: Bacteria introduced during tattooing can cause skin infections, abscesses, or serious blood poisoning (sepsis); unsterile needles risk Hepatitis B/C, HIV.

Allergic Reactions: Itching, swelling, and granulomas can develop from inks, particularly red and white, due to ingredients like azo dyes.

Scarring: Overgrown scar tissue (keloids) can form, sometimes requiring treatment.

Inflammation: The immune system may react to ink as a foreign substance, causing inflammation.

Potential Long-Term Concerns:
Heavy Metals: Inks contain metals (lead, mercury, cadmium) that can travel to lymph nodes, potentially causing issues.

Cancer: Some studies suggest links to melanoma or lymphoma, though research is ongoing, say CBC Radio, Harvard Health, Healthline.

MRI Issues: Tattoos might rarely cause burning or affect MRI image quality.
How to Reduce Risks:

Choose Wisely: Select a licensed, reputable artist who follows strict hygiene.

Check Equipment: Ensure new, sterile needles are used.

Ask About: Inks, ingredients, and their safety, say Indian Express.

Get Vaccinated: Hepatitis B vaccine is recommended, says Mayo Clinic.

Monitor Healing: Watch for signs of infection and follow aftercare instructions carefully, say Healthline.
