Patients undergoing a common treatment for cancer are being warned to carry medical documentation when travelling abroad because the drug can make their fingerprints disappear.
A cancer sufferer was detained at an airport in the United States when immigration officials were unable to take a print from his fingers, his doctor has revealed.
The patient, only referred to as Mr. S, was taking the drug capecitabine, which is sold under the brand name Xeloda and can result in several side-effects. One of them is chronic inflammation of the palms or soles of the feet. Known as hand-foot syndrome, it can result in peeling of the skin, bleeding and development of ulcers or blisters.
