Capecitabine is a common cancer drug, routinely given to patients with head, neck and kidney cancers as well as lymphomas and leukemias. Doctors said very few patients temporarily lose their fingerprints while on Xeloda, but it does happen.
"Most patients will complain they're having difficulty holding things or sensing things," said Dr. Otis Brawley, chief medical officer of the American Cancer Society, who was not linked to the case. "I've never had a patient running into a problem with police authorities, but this is not an exaggeration. It could actually happen."
Unlike most other countries, American immigration officials take two fingerprints from foreign visitors.
