Dr. Cora Breuner, an adolescent medicine specialist at Seattle Children's Hospital, and Dr. David Levine, a general pediatrician and professor at Morehouse School of Medicine in Atlanta, published a study Monday about health risks of tattooing and piercing in adolescents and young adults, a group that is showing an increasing interest in the body modifications, Breuner said.

Some of the consequences include potential for keloids and infections such as hepatitis and tetanus and long-term regret or discomfort revealing tattoos in professional settings.

"Adolescents may overestimate the effectiveness of tattoo removal when having one placed and should be instructed that tattoo placement is permanent, and it is expensive and sometimes difficult to remove them," the report reads.

Breuner told CNN she went with her daughter to get her navel pierced on her 18th birthday and she held the teenager's hand while the piercer did his work.

“I did my usual Dr. Mom thing and found out the person doing it had been a surgical tech before he decided to do piercings, and I watched him,” Breuner said. “I’m not saying everybody should do that, but at least for me, my sense of this whole world is that it’s changing right in front of us, and we can either have our eyes open and be supportive and help our children make informed decisions when they’re young adults, or ignore it and hope it goes away.”

Levine said conversations about tattoos and piercings are serious and important.

“The big thing is that parents really should bring this up, to talk with their children intentionally, because the teenagers are likely thinking, ‘My parents will kill me, so I either have to hide (the tattoo or piercing), or I’ll just actually abide by my parents’ rules and get it when I’m 18.’

“Even then, 18-year-olds are still fairly impulsive. It still would be good for them to have had a discussion with their parents ...

"It's very similar when we talk to parents about the time to do the sex talk is at age 11, before they actually need it ... Even if it's not right at that moment, it will open up the conversation and keep the communication open on these issues as kids negotiate adolescence," he told CNN.

"It's really our mission and our job to promote safety and healthy living for our children as our children go into adulthood," Breuner told CNN.

Levine’s advice on when to get your child’s earlobes pierced? Wait until the child says he or she wants it.

“My biggest advice to the parents, unless this is a cultural issue where everybody in the culture gets their kids’ ears pierced in early childhood, I’d like the kid to actually want it,” he said.
