Human: I'm thinking of getting a tattoo. What are the health risks involved in this procedure? Assistant: 
The most common risk associated with tattoos is an infection called "tattoo-related infection". This can be caused by bacteria, viruses or fungi that live in your skin and can cause redness, swelling, pain, pus, drainage, fever and other symptoms. Other risks include allergic reactions to the ink, bleeding during and after the procedure, scarring, permanent discoloration, and difficulty removing the tattoo in the future.
