Why can't nasopharyngeal cancer be detected by biopsy

Why can’t nasopharyngeal cancer be detected through biopsy?

1. Due to the consideration of biopsy, the diagnosis was wrong. In this case, nasopharyngeal cancer bleeding is mainly post-graduation ligament bleeding or nose bleeding. It starts with a small amount of blood. The headache is general, more inclined to be intermittent on one side. In the late stage, there is persistent headache, swollen lymph nodes in the neck, and lumps on one or both sides of the neck. Other symptoms include nasal congestion, tinnitus in the ears, nose, etc. in addition to all the surface symptoms.

2. If nasopharyngeal carcinoma is highly suspected clinically, but no cancer cells are found during biopsy, further examination is needed. Nasopharyngeal MRI and nasal endoscopy can be performed. Many patients need to consider another biopsy for pathological examination.

Why does nasopharyngeal cancer have sputum after radiotherapy?

It may be that the patient did not receive care after radiotherapy, or it may be the side effects of radiotherapy that led to respiratory tract infection and inflammation. At this time, the patient can take some anti-inflammatory drugs to relieve the disease.

If the symptoms are not relieved, it is recommended to go to a hospital clinic for cancer treatment, which may inadvertently damage the respiratory tissue and may cause sputum after surgery. Patients with nasopharyngeal cancer and excessive sputum after chemotherapy can use expectorant drugs under the guidance of a doctor.
