Through dedicated research, Dr. Papanicolaou developed the “pap test”, used to detect uterine cancer. In developed countries around the world, the widespread use of cervical screening programs using the pap test has reduced the incidence of invasive cervical cancer by more than 50%.
The stamp not only honors the doctor and his work, but reminds us that early detection of cancer is the best defense against the disease.
