Cost of surgery in India is much lower as compared to West

It is interesting to note that Western Countries may be better in most of aspects when compared with India but when it comes to Medical treatment ,we are at par or at times even above them. Further the cost of treatment here is way lower.Recently a US patient was treated in India for a severe case of Scoliosis ,the patient recovered in 3 days and left for home happy.There was additional reason for her happiness,the same surgery which cost her Rs 8 lakh here, would have cost her Rs 80 lakh in her country.
So in terms of surgery we have inherent strengths and cost advantage
