The word “cancer” in literature assumes a surprisingly diverse set of roles, oscillating between its literal reference to a deadly disease and its use as a potent metaphor. In many works, cancer appears as a stark reminder of physical decay and the inevitability of death, marking pivotal moments in a character’s life or symbolizing a relentless, internal deterioration ([1], [2], [3], [4]). At the same time, authors deploy the term metaphorically to describe social decay or moral corruption—what some call a “social cancer” that erodes the fabric of society ([5], [6], [7], [8]). Furthermore, in classical and herbal texts, cancer is entwined with astrological symbolism and natural philosophy, as seen in references to the zodiac sign and celestial influences ([9], [10], [11], [12], [13], [14]). Even in modern contexts, the word surfaces in discussions surrounding health support networks and research communities ([15], [16], [17], [18]), illustrating its enduring impact on both the literal and figurative dimensions of human experience.
