Can Tattoos Prevent Skin Cancer?
This week’s Facebook poll asked: True or False: Does the pigment in tattoos prevent the skin which is tattooed from developing skin cancer? All respondents to the poll answered false which is correct (jeez we need more challenging questions).
On the surface it may seem logical that tattoos can cover the skin, thus shielding it from harmful UVA and UVB rays exposure which could lead to skin cancer. After all some tattoos cover huge portions of the body with dark ink, leading some to believe that the chances of developing skin cancer in the tattooed area is slim to none.
However, in reality, tattooed skin is susceptible to the development of skin cancer. Just as people with darker skin can develop skin cancer, tattooed skin is also susceptible to penetration from UV rays. As such, it is still advisable to take preventive actions such as wearing a high SPF sunscreen or protective clothing and trying to avoid UV exposure.
In fact, tattoos can potentially hide the presence of cancer making diagnosis and treatment extremely difficult. In a study recently published in JAMA Dermatology, researchers in Germany presented the case study of a 29 year old male who developed melanoma on a pre-existing mole that was covered by a tattoo. The melanoma’s existence was hidden until the subject underwent laser tattoo removal treatments. Since the study there have been 16 other similar cases reported in various other medical studies. As such we advise patients to not place a tattoo over or in close proximity to any existing moles.
The good news: there is no evidence that tattoos (or tattoo ink) increase the risk of developing skin cancer (source). So if you’re thinking about it, go ahead and get that new tattoo. Just keep it away from existing moles and exercise normal skin cancer prevention.
