Medical writers create scientific documents and articles. This can include a variety of different types of papers, including research documents, educational or promotional literature, articles, and abstracts. You may ghostwrite for well-known physicians and scientists, or you may write under your own name, depending on what field you are in. Other medical writer jobs include journalists for medical magazines, authors of books, and those who write marketing materials for health care organizations. Regardless of your specialty, you must be able to interpret complex scientific information and create articles that people can read and understand, particularly when writing for the general public.
