India is giving Thailand stiff competition in healthcare services for overseas patients with costs of surgery lower by over 30%, and in fact, cheapest in the entire Southeast Asia. Medical tourism is fast emerging as a big opportunity for India, with its low-cost advantage, high quality healthcare providers and an English speaking populace. Besides offering surgery which is at least 30% cheaper than Bangkok, we have an added advantage with our knowledge of English language, says Dr SK Sama, chairman Sir Ganga Ram Hospital.
