The most reliable basis for distinguishing nasal mucous membrane bleeding from nasopharyngeal cancer is pathological examination, i.e. mucous membrane tissue biopsy. When symptoms of nosebleed or blood in retracted snot occur, one should actively seek medical treatment, and the cause of the disease should be clarified and standardized after specialists ask about medical history and symptoms, physical examination and special examination.
1. Symptoms: One of the symptoms of nasopharyngeal cancer is nosebleed or blood in retracted snot, which is usually a small amount of mucus and blood. Because the mass blocks the nasal cavity, it will cause progressive worsening nasal congestion. Some of them are accompanied by ear symptoms such as tinnitus. Later in life, as the tumor increases in size, headaches can begin and vision problems can occur. Simple bleeding from the nasal mucosa does not have this condition.
2. Physical examination: some nasopharyngeal cancer patients will find obvious lymph node enlargement during physical examination, and some of them will have symptoms such as hoarseness, migraine, choking on food and cough. There is no such condition for simple nasal mucous membrane bleeding.
3. Laboratory imaging examination: nasopharyngoscopy can find mucosal lesions, narrowing or elevation of pharyngeal crypts, etc. Pathological examination of lesions is the gold standard for diagnosing nasopharyngeal carcinoma, and CT or MRI will often find corresponding abnormalities. Simple nasal mucous membrane bleeding only has the change of mucous membrane surface, and the pathological examination is characterized by chronic inflammation.
Nasal mucous membrane bleeding has many causes, such as atrophic rhinitis, sinusitis, etc. If you have related symptoms, you should consult a doctor in time, make a clear diagnosis and standardize the treatment as soon as possible.
