No matter male or female, there is no obvious signal in the early stage of nasal cancer, and with the progress of disease, unilateral nasal congestion and nasal leakage may occur intermittently, and a few of them also have blood in the nasal mucus and blood in the retraction. Nasal cancer often develops unilaterally and has no obvious symptoms in early stage, but with the progress of disease, unilateral nasal congestion and intermittent attacks of nasal leakage may occur, and other symptoms include nosebleed, blood in nasal mucus, bloody pus mucus, blood in the snot, and numbness and pain in the external nasal contour, etc. Therefore, the above symptoms should be detected upon detection. Therefore, once the above symptoms are detected, it is necessary to seek medical treatment in time, especially endoscopy and tissue biopsy are very helpful in confirming the diagnosis of nasal cancer. In advanced stage, nasal cancer can also cause tearing and double vision because the tumor presses the nasolacrimal duct and the eyeball, and when the tumor invades the chewing muscle, it can also cause difficulty in opening the mouth. Patients suspected of nasal cancer are recommended to consult doctor in time, complete examination to make clear diagnosis, and actively cooperate with doctor for treatment, so as to avoid delaying the condition.
