Is there a blood test or X-ray to diagnose moles?
No, there are no blood tests or special X-rays for moles. There are, however, newer digital mole imaging technologies like the SIA scan (SIA = spectrophotometric intracutaneous analysis) or MelaFind that are now available to evaluate moles. These noninvasive, computerized mole-scan devices can help objectively examine a mole and capture information like size, amount, and pattern of pigment, blood flow, and other characteristics. Based on this information, changes in moles or irregular cells may be more readily identified. This technology is fairly new and still developing.
What about UV cameras that show moles?
UV cameras using special black and white images depicting the amount of sun damage may be helpful in some situations to demonstrate sun damage. UV cameras do not diagnose moles or skin cancer.
