Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
Molecular medicine is a broad field, where physical, chemical, biological, bioinformatics and medical techniques are used to describe molecular structures and mechanisms, identify fundamental molecular and genetic errors of disease, and to develop molecular interventions to correct them. The molecular medicine perspective emphasizes cellular and molecular phenomena and interventions rather than the previous conceptual and observational focus on patients and their organs.
How does your patient, doctor?
Not so sick, my lord,
As she is troubled with thick-coming fancies.
William Shakespeare, Macbeth (1605), Act V, scene 3, line 37.
He (Tiberius) was wont to mock at the arts of physicians, and at those who, after thirty years of age, needed counsel as to what was good or bad for their bodies.
Tacitus, Annals, Book VI, Chapter XLVI. Same told by Suetonius, Life of Tiberius, Chapter LXVIII.
