Contours of a booming industry: The health tourism market is booming in Turkey with the number of medical tourists travelling there for plastic surgery, hair transplants, nose surgeries and organ transplants doubling in the past two years. Clients, predominantly from Arab and European countries, often come in tour groups. Turkey’s Health Ministry is looking to boost the numbers of medical tourists to two million and eyeing a revenue target of $20 billion by 2023 by introducing tax-free health-care zones targeted at foreign patients.
