My father was diagnosed with GCT(DER) left arm in 2016 which reoccured twice.he underwent 3 surgeries.later,he lost hope and was depressed and not willing for any further surgery.in 2019 was referred to Dr Rajat Gupta,bone cancer clinic,highly qualified expert in his specialty and a skilled surgeon.he is a very good listener and counseller,empathetic to the concerns of pt.,takes time to clear their doubts.Since one and half year my father is absolutely fine,able to perform activities of daily life very well,drive and can even lift heavy weights.I’m grateful to Sir and highly recommend him.
