quite a great topic here, I believe the main reason we call it a student doctor is done to the fat the person is still at the process of getting informed to the field of practice.
For a student to take complete change means he has been proven to qualify for it, but human life should not be thrilled with to check if you are qualified for it or not, so I believe there should be very clear check before a student can be allowed to do what a professional is doing.
Even though sometimes a student many have one or two things the so called professional don't seem to know because we learn everyday by day, thanks for the topic one more.

I still have a question here what is the possible solution to a prostate cancer patient? What are the best medicine for him and measure.
