papilloma causes
Most papillomas are known to be caused by HPV, which is short for human papillomavirus. The human papillomavirus is behind most cases of papilloma. HPV is also believed to be the cause of most papillomas in tissues beyond the skin, including those occurring in the airway lining. The virus is strongly linked to papillomas even for those lumps that scientists do not completely understand, such as sinonasal papillomas.
