Human: I've heard that if you have a lot of tattoos, you're at a higher risk for skin cancer. Is this true? Assistant: 
Yes, it is true. People who get a lot of tattoos are more likely to develop skin cancers than people who don't have any tattoos. The reason is that tattoos use up the skin's natural protection against ultraviolet radiation (UVR). UVR is a type of radiation that can cause skin cancer.
