Hello @ozod1291ozod and welcome to Mayo Connect. We're glad you found us and no apology is necessary for your written English. At Mayo Connect we are not medical professionals, and cannot diagnose nor offer medical advice.

We can offer our support and share experiences, in the hopes of assisting others. However, your confusion and concern are certainly understandable. Having two doctors give you two different treatment plans makes it difficult to feel comfortable about what is best for you. It is especially confusing when you do not have any symptoms.

Are you able to seek another opinion from another medical center located in your country or in a nearby county?

Mayo Clinic has three locations in the U.S. and there are many international patients who come here for treatment. If you feel like you would want to consider this, here is information about obtaining appointments, http://mayocl.in/1mtmR63
