Nasal polyps are benign neoplasms in the nasal cavity or sinus cavity, appearing as translucent, lychee-like formations without the distribution of nerves and blood vessels. Generally, nasal polyps cannot become cancerous unless they are long affected by other factors, such as possible concurrent conditions like papillomas or mucosal lesions, which could then transform into malignant tumors. However, the likelihood of nasal polyps directly transforming into malignant tumors is extremely rare, and such clinical cases are almost nonexistent. Therefore, from the perspective of pathology or clinical studies, the possibility of nasal polyps turning into nasal cancer is exceedingly small.
