These experiences reinforced his belief in the power of research to drive medical advancements and fueled his determination to contribute to the field [5].
After completing his doctorate, Papanicolaou returned to Greece with the intention of applying his knowledge to improve medical practices in his homeland. However, his return coincided with the Balkan Wars of 1912-13, and like many of his contemporaries, he was drawn into the conflict. Papanicolaou served as a physician in the Greek military, where he gained first-hand experience in the challenges of medical care in wartime. This period of service not only tested his medical skills under pressure but also deepened his understanding of human suffering and the urgent need for medical innovations that could save lives [6].
Following the war, Papanicolaou realized that his aspirations for a career in medical research would be better fulfilled abroad, given the limited opportunities in Greece at the time. In a letter to his father, he wrote: "No, I don't want to be a military doctor. I want to be free, to feel the joy that the struggle of life gives. I'm not afraid of the ocean. I want my freedom, my sweet freedom" [6].
In 1913, shortly after his marriage to Andromachi (Mary) Mavrogeni, Papanicolaou and his wife made the life-changing decision to emigrate to the United States. This move marked the beginning of a new chapter in his life, one that would eventually lead to his most significant scientific contributions [6] (Figure 2).

Upon arriving in the United States, Papanicolaou initially faced numerous challenges, including financial difficulties and the need to establish himself in a new country. However, his determination and passion for research soon led to an opportunity at Cornell University Medical College in New York City. In 1914, he was appointed as a researcher in the Department of Anatomy at Cornell, a position that allowed him to pursue his scientific interests while working alongside some of the leading medical professionals of the time [4].
At Cornell, Papanicolaou's early research focused on the reproductive physiology of guinea pigs, particularly the estrous cycle, which laid the groundwork for his later discoveries in cytopathology [7]. His meticulous approach to research and his ability to draw connections between basic biological processes and clinical applications set him apart from his peers. The skills and insights he developed during these early years at Cornell would eventually lead to his groundbreaking work on the Pap smear, a test that would revolutionize the field of cancer detection and save countless lives worldwide [8].
Thus, Papanicolaou's early life and education were characterized by a relentless pursuit of knowledge, a deep commitment to medical science, and a willingness to overcome obstacles in order to achieve his goals. His journey from a small town in Greece to the research laboratories of Cornell University reflects his enduring dedication to the advancement of medical science and his unwavering belief in the potential of research to transform healthcare.
Review
Development of the Pap smear
Papanicolaou's work at Cornell University marked the beginning of his groundbreaking research in cytopathology. Initially, he conducted research on the estrous cycle of guinea pigs, which led him to observe cellular changes in the vaginal smears of these animals. These observations sparked his interest in applying similar techniques to humans to detect cellular abnormalities [5] (Figure 3).

In 1928, Papanicolaou presented his preliminary findings at a medical conference, suggesting that vaginal smears could be used to detect uterine cancer. However, his ideas were met with skepticism, and it took years of persistent research and advocacy before the medical community began to recognize the significance of his work [2].
Collaborating with Dr. Herbert Traut, a gynecologist, Papanicolaou conducted extensive studies and published their findings in 1943 in the landmark monograph "Diagnosis of Uterine Cancer by the Vaginal Smear". This publication provided comprehensive evidence of the efficacy of the Pap smear in detecting cervical cancer at an early, treatable stage [9].
Impact on women's health
The introduction of the Pap smear revolutionized women's health care. Before its widespread use, cervical cancer was a leading cause of death among women. The Pap smear enabled the early detection of precancerous and cancerous cells in the cervix, significantly reducing mortality rates. Public health campaigns and screening programs based on Pap smears have saved countless lives by identifying cervical cancer in its early stages when it is most treatable [3] (Figure 4).
