In an interview for the Oldie magazine, oncologist Prof. Karol Sikora has recommended being as nice as possible to those that treat your health conditions. “If someone is particularly helpful be appreciative – everybody likes positive feedback,” he told John Sutherland. Sikora is promoting his new book The Street-wise Patient’s Guide to Surviving Cancer in which he advises patients to charm their doctors if they hope to persuade them that they are worth ruinously expensive cancer drugs. NHS staff are “dedicated and remarkably caring”, he said, “and they naturally respond well to pleasant patients.” His advice,though to “tell someone they have a lovely smile,” might come across as a bit obsequious though, not to mention downright creepy in some situations.
