Nasal polyps: Some abnormal growth in the nasal cavity or paranasal sinuses is non-cancerous or non-malignant, but still capable of causing problems – Nasal Polyps and papillomas are such growths.

Nasal polyps

These are abnormal growths present inside the nasal cavity or paranasal sinuses. They have smooth surface and looks like teardrop in shape. They are mostly benign (non-cancerous) and may be due to persistent inflammation in the nose. Nasal cancers can be easily differentiated from nasal polyps by careful examinations and tests. However, doctors watch them closely and keenly to be hundred percent sure that they are not cancers. In some cases, small polyps that are not causing any problems, might not be treated. However, ENT surgeons treat larger problematic polyps with surgery or medicine.


Papillomas are firm abnormal elevated blemishes (warts) that can grow inside the nasal cavity or paranasal sinuses by overcoming healthy tissue growth. They usually have rough and irregular surface, but their growth is not cancerous. Sometimes, a papilloma can harbour squamous cell carcinoma – which starts within it. Owing to the high risk associated with the papilloma due to the possibility of cancerous growth within it, papillomas are often removed by surgery from nasal cavity and paranasal surfaces.

Inverting papilloma: In other words, it is a benign tumour, but often behaves quite abnormally acting like a nasal cancer. Though it is classified as benign tumour, it can come back and grow into nearby cells and tissues. Doctors treat inverted papillomas with the same type of surgery they perform to treat cancers.
