As more and more people live longer, there will be a grater demand for medical treatments that are
effective, cheap, and available to everyone. Scientists are finding new ways to understand how the
body works, and this new understanding could well lead to more personalized treatment. Personalized
medicine will undoubtedly have enormous benefits to public health because it will help doctors and
therapists to identify a patient’s health problems earlier and treat them successfully. This should also
reduce medical costs to patients.
