What Arimeh said I'm a biomedical Scientist. Biomedical doctor is misused term as far as im concerned- they are not doctors. Biomed involves a 4 year medical based degree as opposed to the 6-7 for a medical doctor. Biomed degrees are usually used as an alternative path in to medicine, clinical research ( what I do) and other laboratory based work. Your friend may have their terminology incorrect.... I've never heard the term "biomedical doctor" used :/
