Can a normal nasal endoscopy rule out nasopharyngeal carcinoma?

Can a normal nasal endoscopy rule out nasopharyngeal carcinoma?

1. Relatively speaking, if the nasopharyngeal endoscopy is normal, this type of nasopharyngeal carcinoma can be ruled out. However, some cases belong to submucosal nasopharyngeal carcinoma. In this case, the nasopharyngeal endoscopy is normal, or no obvious new growth is seen. An imaging examination of the nasopharynx is required, such as nasopharyngeal CT or nasopharyngeal MRI. These two imaging examination methods can be used to rule out submucosal nasopharyngeal carcinoma. Generally speaking, nasopharyngeal carcinoma can be ruled out only after a comprehensive clarification of the diagnosis through nasopharyngeal endoscopy and imaging examinations.

2. Clinically, nasopharyngeal carcinoma can be divided into ulcerative, hyperplastic and submucosal types. However, nasal endoscopy can only detect ulcerative and hyperplastic types, while the submucosal type cannot be seen. If a patient is considered to have nasopharyngeal carcinoma, a CT scan of the nasopharynx is also required to completely rule out the possibility of nasopharyngeal carcinoma.

Will a renovated room cause nasopharyngeal cancer?

If you have bloody nasal discharge, blood when blowing your nose, nasal congestion, and difficulty breathing, these are symptoms of nasopharyngeal cancer and you should go to the hospital for a check-up as soon as possible. Decorating your house will release more formaldehyde, which can cause blood system diseases and rarely lead to nasopharyngeal cancer. However, you should go for a check-up if you have symptoms to rule out cancer. The situation you describe cannot be completely determined to be malignant. You should be careful not to eat spicy and irritating foods and eat a light diet. You can use formaldehyde-removing drugs to purify the room. The main thing is to maintain your physical fitness and improve your immunity.
