He answered all my initial questions and the ones I've sent after his initial answers in meter of few days
I requested a second opinion for the treatment of prostate cancer for my dad. The cosultation was provided in written by Prof. Dr. med. Sebastian Melchior. He answered all my initial questions and the ones I've sent after his initial answers in meter of few days. This helped us in understanding better the situation and possible options. However due to the fact that most of the answers were of general rather specific nature, in the end we are still not sure what is the better treatment in our case.
About Bookimed service
The biggest issue I had is the initial contact with bookimed. Contact forms and email from the site didn't work. Once finally contacted the process was smooth and easy.

The German specialist's consultation was complete
I have not been to the clinic. There was a dialogue on ZUM. The second opinion presented basically coincided with the Russian one. It was helpful. Various technologies and their applicability were considered. The German specialist's consultation was complete.
