The symptoms of nasal cancer can be numerous. In the early stages, symptoms might not be apparent because the area affected is relatively small, which can make the symptoms unclear. Possible symptoms include bloody nasal discharge and poor nasal airflow. Some patients might experience a foreign body sensation in the nasopharyngeal area. The most important thing, however, is to use diagnostic aids to make an assessment. This can include a nasopharyngoscopy, an enhanced CT of the nasopharynx, or an enhanced MRI to preliminarily determine the presence of a tumor. If a tumor is suspected, it is possible to consider performing a biopsy and lab tests under endoscopy. Only after completing the biopsy and lab tests can it be confirmed whether it is nasopharyngeal cancer, and then further treatment plans can be considered.
