Cosmetic tattoos can also be used to cover up surgical scars, like scars from mastectomy (surgical removal of the breast). The use of artistic tattoos to cover mastectomy scars is becoming more popular in the United States and the United Kingdom. Cosmetic tattooing is also used to tattoo nipples onto reconstructed breasts after breast reconstruction surgery (where the breast which was removed during mastectomy is re-created using fat from another part of the body).
