Read the following article and select the best answer. Article: A dentist's office may not be everyone's idea of a perfect holiday destination.But a growing number of Europeans are travelling abroad for medical treatment to save money,or maybe to combine a visit to the doctor with some sightseeing,creating a potential but fastgrowing market for traditional tour operators. "It was simply cheaper for me to go to a dentist in Hungary," said a 42yearold physical therapist from Berlin.He chose the clinic near Budapest from an Internet advertisement,attracted by hundreds of euros in savings compared with the same treatment in Germany.He was happy to find when he got there that the clinic was clean,the staff qualified and the work thorough. People travel abroad for medical treatment for various reasons:it's cheaper,they face a long wait at home,or the treatment they want is not available in their own country.The Britishbased Medical Tourist Company refers about 100 patients a year to hospitals in India for treatments.And Chief Executive Premhar Shah reports rapid growth in demand from customers in Africa,where it can be harder to find wellequipped medical facilities for complex surgeries. Some patients who have immigrated may prefer to return to be close to their families when they undergo surgery."People will want to take the opportunity to seek treatment in places where they have relatives who might be able to look after them.I'm seeing that especially with younger people from eastern Europe," said a professor at the University of Oxford. For some,there is the attraction of free treatment abroad.British lawmakers have called for tighter checks on patients arriving for treatment,out of concerns that foreign citizens are travelling to Britain to take advantage of the free service. The global medical tourism market is believed to be worth $40 billion to $60 billion and growing at about 20 percent per year.
