India is set to earn Rs 8,000 crore ($1.87 billion) a year in foreign exchange from medical tourism by 2012, according to a study by the Associated Chambers of Commerce and Industry of India (Assocham).

With easy visa facilities to overseas patients coupled with best emerging medical infrastructure facilities, India's medical tourism can become a lead foreign exchange earner and the earnings will grow from the existing Rs 3,500 crore annually to Rs 8,000 crore a year by 2012, Assocham president Venugopal N Dhoot said.

The study on Prospects of Medical Tourism for Higher Forex Earning was done under the supervision of the health committee of Assocham, headed by Sir Ganga Ram Hospital chairman B K Rao.

"The primary reasons as to why medical tourism would flourish in India include much lower medical treatment costs for various ailments, such as bone narrow transparent, bye-pass surgery, knee surgery and liver transplant as compared to western countries," Dhoot said in a statement Monday.

"The cost of medical treatment is very high in the western countries, forcing patients from Africa, the Gulf and various other Asian countries to explore medical treatment in India," he said.
