Tumors of the nasal cavity are not always cancerous. Because there are benign and malignant nasal tumors, benign tumors generally include nasal polyps, nasal papilloma, and nasal fibrovascular tumor, while malignant tumors are usually squamous cell carcinoma, and often lymphoepithelial carcinoma, migratory cell carcinoma, basal cell carcinoma, and mucous epidermis-like carcinoma can also be seen. If nasal tumors are found, first of all, you need to go to the hospital to check electronic rhinoscopy as well as sinus CT. Electronic rhinoscopy can see the middle or common nasal tract of the nasal cavity and can detect abnormal neoplasms. If it is a benign tumor, the surface is usually smooth, soft, painless and not easy to bleed. In the case of malignant tumors, cauliflower-like neoplasms or crater-like ulcers can be seen, which are brittle and bleed easily with pain when touched locally. After the foreign body is found, local pathology must be taken to clarify its nature first. If it is a benign tumor, related surgery can be performed; if it is a malignant tumor, a whole body examination, such as neck ultrasound, thyroid ultrasound, lung CT, abdominal ultrasound, etc., is also needed to see if there are metastases in other areas. If there is metastasis, surgery and systemic radiotherapy or chemotherapy will be required.
