A deviated nasal septum does not lead to cancer, as the main cause of a deviated nasal septum is either congenital malformation or trauma resulting in nasal fractures or deviations.

The primary site of deviation is the cartilage of the nasal septum or the posterior bony part. This may lead to narrowing of the nasal passageway, potentially causing symptoms such as nasal congestion, headaches, and nosebleeds. However, overall, this condition is benign and unlikely to become cancerous.

In terms of treatment, minor deviations might not require any intervention, but prominent deviations causing clinical symptoms might necessitate surgical correction.
