We know more about human physiology than ever before, thanks to scientific feats such as fully sequencing the human genome. Medical treatment, subsequently, is becoming more tailored to the individual, which is known as precision medicine (or personalized medicine). By ruling out patients for certain drugs and treatments based on their unique physical makeup, patients in theory can avoid the expense and side effects of treatments that have no hope of working for them.
Since the completion of the Human Genome Project, the promises of precision medicine have been promoted at length. While the vision has not yet come to pass, the advent of machine learning and artificial intelligence may help realize this dream.
