Avicenna, the Prince of Physicians, and His Philosophy of Cancer

Day 29 (The History of Cancer in 365 Days Series)
In the West, the "Prince of Physicians"; in the East, the "Chief of Physicians." A genius's intellectual reckoning with cancer, the "dark enigma," on a journey from the dusty roads of Bukhara to the summit of medicine.
Human history has been written not only through the rise and fall of empires but also through humanity's silent struggle with its own body. The most stubborn front in this struggle is undoubtedly cancer. While modern oncology now searches for this disease within the strands of DNA, exactly a thousand years ago, in the heart of Central Asia, a genius was seeking answers to the same questions through "the mind's eye": Ibn Sina (Avicenna).
He was not merely a physician writing prescriptions. He was a system builder who applied Aristotle's logic to medicine, classified diseases with mathematical precision, and, through his The Canon of Medicine (Al-Qanun fi al-Tibb) , was regarded as an "unquestionable authority" in European medical schools for 600 years. But how did this man who "achieved the impossible" view cancer (saratan), the most feared disease of his time? This article offers not only a medical analysis but also the fascinating story of the metaphors of "Black Bile" and the "Crab" in a genius's mind.
Portrait of a Genius: "The Child Without a Teacher"
Born in 980 in Afshana near Bukhara, Avicenna had memorized the Quran and classical literature by the age of 10. By 16, he had dismissed medical books as "too easy." His journey changed when he cured the Samanid emir Nuh ibn Mansur of a life-threatening illness. At just 17, there was only one reward he wanted: Access to the Palace Library.
Amid political upheaval, Avicenna wrote his works sometimes from a vizier's seat and sometimes from a prison cell. Here are some of the "firsts" he inscribed in medical history:
-
Psychosomatic Medicine: He diagnosed a prince suffering from "lovesickness" simply by feeling his pulse and measuring the rise in his heartbeat when he heard the name of the girl he loved. He was the first physician to demonstrate the mind's influence on the body.
-
Infectious Diseases: He discovered that tuberculosis was contagious and proposed the method of "Quarantine" to prevent its spread.
-
Anatomy: He drew the anatomy of the eye and the function of the retina in greater detail than anyone had before.
The Philosophy of Cancer: The Curse of "Black Bile"
According to Avicenna, the universe consisted of four elements (fire, air, water, earth), and the human body of four fluids (humors). Health was the balance of these fluids (Krasis), whereas disease was chaos (Dyskrasis). Cancer was the darkest form of this chaos.
Hot and Moist (Spring)
Cold and Moist (Winter)
Hot and Dry (Summer)
"The Fluid of Earth and Sorrow"
Nature: Cold and Dry (Autumn)
Pathology: Burning and Sedimentation
"Burnt Bile"
Avicenna argues that cancer results not simply from an increase in black bile but from the "burning" (oxidation) of this substance, which changes its qualities and makes it toxic. When this "burnt and sharpened" substance settles in an organ (for example, the breast), it hardens the tissue, impairs its nourishment, and transforms it into a "malignant" structure.
Melancholy and Cancer: Even more interestingly, Avicenna combines this theory with psychology. He states that people of a "melancholic" temperament (dominated by black bile), constantly experiencing sadness, fear, and stress, are more prone to cancer. This is the intuitive discovery, a thousand years ago, of the relationship between "stress and the immune system" in modern medicine.
"Saratan": The Anatomy of a Metaphor
Why was cancer called the "Crab" (Arabic: Saratan, Greek: Karkinos)? Although this comparison comes from Galen, Avicenna deepens it in the Canon through not only a visual but also a "behavioral" analysis:
The "Cold Tumor" Paradigm
Avicenna gives physicians a very clear key to distinguishing cancer from other swellings (abscesses, cysts): Heat and Cold.
WHY COLD?
Abscesses are "hot" because the body fights them (inflammation/fever). Cancer, however, is "cold" because that tissue has lost its vitality and become a dead burden hardened by black bile. It feels colder to the touch than the surrounding tissue.
-
Hardness: It is as hard and heavy as stone.
-
Stealth: Initially painless, it grows secretly like a small chickpea.
-
Taking Root: It adheres to surrounding tissues (becomes fixed) and cannot be moved.
DROZDOGAN Academy Commentary
Reading Avicenna, we encounter a vision of "holistic oncology" stretching across a thousand years to the present. He saw cancer not merely as a swelling in the breast but as a systemic problem involving the whole body, from the patient's mood (melancholy) to diet and metabolism (liver/bile). The theory of "Burnt Bile" is the language of that time for what we now know as "chronic inflammation and oxidative stress." Avicenna advises us: Treat the patient and their entire balance, not the disease.
