New fluorescent cancer ‘tattoos’ given to patients in radiotherapy are invisible in daylight

Permanent ink markings on the skin are a vital part of cancer treatment, but often a lasting reminder for patients of their illness long after they recover. The tattoos, given as part of radiotherapy, are vital to ensure that the powerful tumour destroying rays are directed at exactly the same spot each session, which can be weeks apart. Now doctors are trialling fluorescent tattoo ink that is only visible under UV light and it spares patients negative feelings about their bodies, according to results from a pilot study presented at the National Cancer Research Institute (NCRI) Cancer Conference.
