Can Nasal Polyps Cause Cancer ?
Nasal polyps are soft pieces of swollen tissue hang like grapes on a vine. They grow inside your sinuses or nasal cavity, the area behind your nose. Nasal polyps are often linked to other conditions. These conditions cause inflammation, which triggers nasal polyps to grow. In multivariate analyses, which controlled for smoking, asthma, allergic rhinitis, and other factors, the relative risk of participants with nasal polyps developing NCPS was slightly attenuated, with a hazard ratio (HR) of 6.24, as well as for nasopharyngeal cancer, with an HR of 1.58, compared with controls. Nevertheless, the association between the presence of nasal polyps and heightened risk of both NCPS and nasopharyngeal cancer remained positive even among participants who had never smoked, they note. In older individuals, "the nasal polyp–cancer relationships were consistently significant regardless of [the presence] of asthma comorbidity," the investigators point out. They also observed a trend, alb...
