Dr W Szpak comments on the attached Medscape article about the risks of tattoos,

“There is no reason ​to ​panic but ​a tattoo must be done by trustworthy people who take care with​ proper hygiene and their equipment.

Small Tattoo ​= ​small problem, many huge tattoos may however affect the​ lymphatic system that tries to clean skin from pigments.

​ The risk of infection from tattoos may affect the liver​ which could in turn cause hepatitis which may cause liver cancer. David Bowie died from liver cancer caused by an infection from a contaminated needle.”
