This is the most common symptom of nasal cancer. When the cancerous tissue is very small and confined to the nasal cavity or sinuses, this symptom is the only "alarm" signal, and there is often little bleeding, sometimes only nosebleeds, so it is ignored by patients. So pay special attention, especially to middle-aged people over 40. If you have symptoms, please see a doctor.

● Unilateral nasal obstruction

Unilateral nasal obstruction appeared earlier in nasal cancer, but later in nasal sinus cancer. With the enlargement of tumor tissue, nasal congestion becomes heavier and heavier, showing persistent nasal congestion. This is different from the general rhinitis with alternating nasal congestion on both sides. After dripping 1% ephedra solution, nasal ventilation can not be improved as obviously as rhinitis. In addition, when the tumor tissue necrosis or mixed infection, there will be a special smell of nasal mucus.

Low cheek swelling, pain and numbness.

This is mainly a symptom of nasal sinus cancer. Some of these patients can feel the swelling under the local skin.

● Eye symptoms

Including unilateral solid eye, diplopia, red eye, tears, eye swelling and pain, decreased vision and so on. These symptoms usually appear earlier in ethmoidal sinus cancer. Eye symptoms can also occur when upper sinus cancer and frontal sinus cancer spread to the orbit. Patients often go to ophthalmology first and then to otolaryngology.

● Oral symptoms

The most common symptoms are toothache, loose teeth and difficulty in opening mouth. These symptoms are mainly related to maxillary sinus cancer. Because the top of the mouth is the bottom wall of the maxillary sinus, the lesions of the maxillary sinus often have the above dental symptoms, especially the symptoms of the first, second molars and second bicuspids on the affected side. Some patients have almost all their upper teeth pulled out because of toothache, but the toothache has not been alleviated, and then cancer will drill out at the painful place. The diagnosis is clear, but the lesion has spread.

● Other symptoms

Some nasal cavity swelling and deformation, cervical lymph node swelling, headache, general health deterioration and so on. Most of them are symptoms of advanced cancer.

Generally speaking, surgery is the main method for nasal cavity, supplemented by preoperative and postoperative radiotherapy and chemotherapy, and the surgical path is mostly nasal cavity or lip incision. Surgery is the main comprehensive therapy for patients with sinus limitation, and the first treatment is the key to success or failure.
