Nasal polyps are painless soft growths inside your nose. Nasal polyps are usually pearly grey in colour, and they vary in size. Each polyp is a soft teardrop-shaped swelling which hangs down, resembling a small grape within the nose. Nasal polyps are difficult to see, and they may not cause any symptoms, so many people don’t realise they have them.
Nasal polyps will usually only cause a problem if they become large or grow in clusters. In these cases, nasal polyps can block your nasal passages leading to breathing problems, a loss of sense of smell and frequent infections
Nasal polyps are benign (non-cancerous) growths and may not cause any symptoms.
