What is the difference between nasal polyps and nasal malignant tumors?

There are vegetations in the nasal cavity, and many patients will worry: Is this nasal polyp or nasal cavity malignant tumor? Nasal polyp is a common nasal disease, which usually occurs on the lateral wall of nasal cavity and the tip of nose. It is not a real tumor, but the extremely edema nasal mucosa and sinuses are gradually drooping under the action of gravity. What is the difference between it and nasal cavity malignant tumor? ? 1, nasal polyps show persistent nasal congestion, which is due to poor capillary circulation in the nasal cavity, leading to nasal congestion, decreased sense of smell, nasal obstruction, sleep snoring and mouth-opening breathing. Nasal tumors are mostly smooth, gray or reddish translucent, soft, painless and displaceable. Biopsy showed no cancer cells, nosebleeds and nosebleeds, and no foul secretions. 2. Malignant tumors of nasal cavity are mostly secondary to maxillary sinus and ethmoid sinus, and primary tumors are rare. When the early tumor partially invades the nasal cavity, intermittent nasal congestion and a small amount of nosebleeds or nosebleeds may appear on one side. When the tumor is necrotic and ulcerated, bloody and foul purulent secretions often appear. The gradual enlargement of the tumor will lead to persistent nasal congestion. Examination showed that the nasal tumor was pink or grayish red with rough surface or ulceration. Some tumors may be papillary, mulberries or irregular. Tumors are fragile and easy to bleed when touched. 3, nasal cavity malignant tumor can also occur distant metastasis, which can have various manifestations in the eyes, neck and head. When the tumor invades the orbit, there may be symptoms such as exophthalmos, exophthalmos, diplopia and tears overflow. The examination showed that the eyes were asymmetrical, the patient's eyeball was prominent and displaced, and the inside of the orbit was full and bulging. When the tumor metastasized to the neck, the ipsilateral neck mass appeared, which was hard and could not be pushed. Patients often have nervous headache and head swelling. Advanced tumors invade the skull base, resulting in corresponding cerebral palsy symptoms. With the development of the disease, there will be distant metastasis of organs such as lung and liver.
