Early symptoms of nasopharyngeal cancer

When we suffer from nasopharyngeal cancer, it will be very painful and it will also cause serious damage to the patient's body. Therefore, everyone needs to be alert to the occurrence of nasopharyngeal cancer and need to have a thorough understanding of the symptoms of this disease. Next, I will introduce to you what the symptoms will be after the onset of nasopharyngeal cancer.

A malignant tumor that occurs in the nasopharyngeal mucosa. Guangdong, Guangxi, Fujian, Hunan and other places in China are high-incidence areas, with more males than females. Most of the patients are middle-aged, and there are also teenagers who are sick. The cause is related to racial susceptibility (yellows are more likely to be sick than whites), genetic factors, and Epstein-Barr virus infection. Nasopharyngeal carcinoma is a highly invasive tumor that invades deep structures in the early stages. The nasopharynx causes different syndromes due to different ways of spread: ascending (type A) extension, descending (type D) metastasis, and ascending and descending (type AD). What are the early symptoms of nasopharyngeal carcinoma? Nasopharyngeal carcinoma refers to a malignant tumor that occurs in the nasopharyngeal mucosa. Most of the patients are middle-aged, and there are also teenagers who are sick. The cause of nasopharyngeal carcinoma is related to racial susceptibility (yellows are more likely to be sick than whites), genetic factors, and Epstein-Barr virus infection. Nasopharyngeal carcinoma is highly malignant, and cervical lymph node metastasis can occur in the early stages.

Early symptoms of nasopharyngeal carcinoma Nasopharyngeal carcinoma is a chronic tumor. There are many cases in my country. Because its site of onset is relatively hidden, the early symptoms are not easy to detect. Headache. Headache may occur in the early stage, and it is mostly biased to one side and intermittent: in the late stage, there will be continuous severe headache, which is easy to be mistaken for neuralgia. But I don’t know that this may also be one of the early symptoms of nasopharyngeal carcinoma. Swollen lymph nodes in the neck. Lumps appear on one or both sides of the neck, which are impotent, hard, and have poor mobility. They are often easily mistaken for lymph tuberculosis or lymphadenitis. Swollen lymph nodes may also occur in the early symptoms of nasopharyngeal carcinoma. In addition, the early symptoms of nasopharyngeal carcinoma, in addition to showing one or all of the above symptoms, may also include nasal congestion, ear closure, tinnitus, numbness of the ears, diplopia, upper and lower ptosis and other symptoms. Late-stage cancer is prone to invade the brain and metastasize to distant places such as bones, liver, and lungs.

Retractile bloody mucus often occurs in the morning after getting up, when bloody mucus comes out of the mouth. The amount of blood is not much, and it is often ignored by patients. Retractile bloody mucus is one of the typical precursors of nasopharyngeal carcinoma. Tinnitus, hearing loss, and a feeling of blockage in the ear are early symptoms of nasopharyngeal carcinoma such as unilateral tinnitus or hearing loss, catarrhal otitis media, etc., because when the lesion occurs in the lateral wall of the nasopharynx or the opening of the Eustachian tube, the tumor compresses the Eustachian tube and causes unilateral tinnitus or hearing loss, catarrhal otitis media, etc. Refractory otitis media is manifested as unilateral ear canal discharge, tinnitus, hearing loss, and tympanic effusion. Nosebleeds, except for a few occasional bloody mucus, basically have no subjective symptoms, especially when blowing your nose in the morning, you should be more vigilant.

Headache. When NPC is first diagnosed, about 70% of patients have headache symptoms. The headache symptoms of NPC often manifest as migraine, pain behind the occipital bone or neck. Most NPC headaches are related to the invasion of the skull base bones, nerves and blood vessels by cancerous tissue. Unilateral nasal congestion symptoms. This symptom is not obvious in the early symptoms of NPC. As the NPC grows, the symptoms become progressively worse. The nasal congestion symptoms are different from those of colds. They manifest as unilateral nasal congestion and are ineffective in anti-cold treatment. Unilateral facial paralysis symptoms. When NPC invades the cranial nerves, it can also cause facial paralysis symptoms, decreased vision in the affected eye, or symptoms of diplopia. These early symptoms of NPC are sometimes the main complaints of some patients at the first visit. Neck mass symptoms. According to statistics, about 80% of NPC patients have lymph node metastasis behind the subclavian and below the earlobe. NPC grows rapidly and may not have any early symptoms of NPC. At first, it can move, but then NPC adhesions occur in a short time and become immobile.

The above are the symptoms of nasopharyngeal cancer. The incidence rate of nasopharyngeal cancer is quite high among nasal diseases. It will seriously damage the patient's nasal health and make the patient particularly painful. We should be careful about the occurrence of nasopharyngeal cancer, learn more about the symptoms of this disease, and especially prevent nasopharyngeal cancer.
