Tattoo Ink Chemicals May Pose Cancer Risks

Some tattoo inks have chemicals that might be harmful.

These chemicals can build up in parts of your body called lymph nodes.

Scientists are worried that this could lead to cancer over a long time.

However, they haven't proven that these inks definitely cause cancer.

They just want people to be careful because some of the colors and other things in the ink might not be safe.
