Medical tattoo
A medical tattoo is a tattoo used to treat a condition, communicate medical information, or mark a body location for treatment. People may get a paramedical tattoo to conceal a condition or the effects of treatment, such as creating the appearance of an areola after breast reconstruction, or a cover-up tattoo to disguise the area in an artistic way.
Historical uses

To provide medical information
During the Cold War, threats of nuclear warfare led several U.S. states to consider blood type tattooing. Programs were spurred in Chicago, Utah and Indiana based on the premise that if an atomic bomb were to strike, the resulting damage would require extremely large amounts of blood within a short amount of time.<ref>Template:Cite news</ref><ref>Template:Cite news</ref><ref>Template:Cite news</ref><ref>Template:Cite journal</ref>

Paramedical tattoos

During breast reconstruction after mastectomy (removal of the breast for treatment of cancer), or breast reduction surgery, tattooing is sometimes used to replace the areola which has been removed during mastectomy, or to fill in areas of pigment loss which may occur during breast reduction performed with a free nipple graft technique.<ref name="Potter2007">Template:Cite journal</ref> Since September 2011, the Royal Derby Hospital offers free nipple tattoos for breast surgery patients in order to mask the scars of surgery.
