Hello and welcome to HCM,
It is illegal to sell or buy organs.
There are some organs like
cornea, heart, brain,
liver, kidneys which are donated after the death of the person. Consent is very important in
organ donation. The consent is given by the donor during his/ her life or by the nearest kin after death.
And there are some organs which can be donated during life of person like
bone marrow, one side kidney and part of liver during life of the person.
The high cost involved in transplants is associated with expertise of the procedure and the cost of the organ.
However, it is not as high as mentioned by your friend.
The cost is in few lakhs, more in private centers as compared to that in government ones.
Thanks and take care.
Dr Shailja P Wahal
