Health notes: New fluorescent cancer 'tattoos' given to patients in radiotherapy are invisible in daylight Permanent ink markings are used as part of radiography cancer treatmentÂ 'Tattoos' are used to focus rays on exactly the same point each session However, they give patients a lasting reminder of the suffering enduredÂ Now doctors are trialling tattoo ink that is only visible under UV lightÂ More than half of women using fluorescent ink feel better about bodiesÂ 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. Permanent ink markings are given to cancer patients as part of radiography treatment, but doctors are trialliing 'tattoos' which are only visible under UV light (file picture) Until now, doctors have used dark ink - either in pen, or often in theÂ form of a shallow tattoo - on the skin. However, the Royal Marsden Hospital, London has been using the new approach on breast cancer patients. Half the women in the study were offered fluorescent tattoos, only visible under UV light, while the other half had conventional dark ink tattoos. The researchers found that 56 per cent of the women who had fluorescent tattoos felt better about their bodies one month after treatment, compared to only 14 per cent among those who received black ink tattoos. Using fluorescent tattoos made no difference to the accuracy of treatment and took only slightly longer to carry out, compared to conventional dark ink tattoos. Another advantage was they showed up better on dark-skinned women.Â Professor Matthew Seymour from the National Cancer Research Institute is urging more developments like these to reduce the long-term impact of cancer treatment on patients.Â â€˜With more than half of all cancer patients now surviving 10 years and beyond, itâ€™s imperative that we do everything we can to reduce the long term impact of treatment on patients, including cosmetic changes,â€™ he said.Â Prebiotic supplement Bimuno could be used to treat anxiety, scientists hope Prebiotic supplement Bimuno could be used to treat anxiety. A clinical trial, conducted by the University of Oxfordâ€™s Department of Psychiatry and published in the journal Psychopharmacology, looked at the effect of the powder on levels of stress hormones in the body, as well as mood. Nearly one Briton in five claims to feel anxious â€˜a lot or all of the timeâ€™, while panic, phobias, depression and obsessive behaviours are the most commonly suffered mental health problems. The study, on 45 healthy people, claims nutritional therapies might aid the management of these conditions, with Bimuno found to reduce the amount of stress hormone the most. Trials are now planned on individuals suffering anxiety.
