The specific cause of nasopharyngeal carcinoma, a type of malignant tumor, is currently unclear, but it is considered to be related to some high-risk factors that may lead to the occurrence of nasopharyngeal cancer.

Firstly, there are cases of EB virus infections in the nasopharyngeal area. The long-term stimulation of the nasopharyngeal mucosa by this virus leads to hyperplasia of the mucosa, which can become malignant and eventually form nasopharyngeal cancer.

Additionally, some clinical studies suggest that the occurrence of nasopharyngeal carcinoma is related to genetic factors, indicating a genetic predisposition to nasopharyngeal carcinoma, which leads to its development.

Furthermore, some considerations involve external carcinogenic factors affecting the nasopharyngeal area, such as long-term smoking or environmental air pollution, which can also lead to a high incidence of nasopharyngeal cancer.

The Difference between Nasopharyngitis and Nasopharyngeal Carcinoma

The differences between nasopharyngitis and nasopharyngeal carcinoma are very clear. Firstly, nasopharyngitis is an acute inflammatory irritation, while the cause of nasopharyngeal carcinoma is currently unknown, generally associated directly with EB virus infection. Secondly, their clinical manifestations are different. Patients with nasopharyngitis may experience dryness and pain in the nasopharyngeal area, and yellow secretions may occur when clearing the throat in the morning. In contrast, nasopharyngeal carcinoma typically presents as a painless mass. During examination with a nasopharyngoscope, the surface of nasopharyngitis is congested and swollen, whereas in nasopharyngeal carcinoma, cauliflower-like neoplasms or ulcers can be found at the top of the nasopharynx or near the pharyngeal recess. A local pathological examination can reveal symptoms and clarify the diagnosis. In terms of treatment, nasopharyngitis requires symptomatic anti-inflammatory treatment, while nasopharyngeal carcinoma requires local radiotherapy or chemotherapy.

Is a fever in nasopharyngeal carcinoma a sign of deterioration?

Patients with nasopharyngeal carcinoma may exhibit fever in a clinical setting. This fever can partially be due to the worsening of the carcinoma itself. However, not all cases are due to progression of the disease; some are caused by infections and other factors. For example, after receiving anti-tumor treatments such as radiotherapy and chemotherapy, patients with nasopharyngeal carcinoma may experience a decrease in white blood cells, making them highly susceptible to infections, which can then manifest as fever. Additionally, patients with nasopharyngeal carcinoma may have weakened immune systems, making them prone to infections and fevers. As the nasopharyngeal carcinoma progresses, it can release abnormal hormones, forming endogenous fever-inducing agents, leading to clinical manifestations of fever. Generally, this type of fever is referred to as tumor fever, which is often related to the progression of the disease. Tumor fever typically requires anti-tumor treatment for effective relief.

How is nasopharyngeal carcinoma diagnosed?

The examination of nasopharyngeal carcinoma is mainly divided into two major categories. The first category is imaging examinations, and the second category is pathological biopsy tests. Imaging examinations primarily involve performing a CT or MRI of the nasopharyngeal area to determine the scope of the cancerous changes in the nasopharynx, which is quite helpful for clinical staging and typing. It also plays a role in designing targeted therapy for subsequent radiation treatment. Pathological testing is an important means for diagnosing nasopharyngeal carcinoma. Generally, it requires a nasopharyngoscopy. If cancerous changes are suspected during the nasopharyngoscopy, a pathological biopsy can be taken simultaneously. After the biopsy, the specific differentiation degree and type of cancer can be determined. Then, in conjunction with the imaging examinations, a plan for radiotherapy and chemotherapy can be formulated.

How to check for nasopharyngeal carcinoma?

Nasopharyngeal carcinoma is a malignant tumor in the nasal area, clinically mainly squamous cell carcinoma. The incidence of nasopharyngeal carcinoma is relatively high in southern regions of our country. Clinically, the primary treatment is radiotherapy. For diagnosis, the first general step involves using an electronic nasopharyngoscope to examine the nasopharyngeal area for suspicious conditions. Further imaging studies can also be conducted, such as CT scans and MRI scans of the nasopharyngeal area. Through these examinations, if a neoplasm in the nasal area is essentially identified and suspected to be nasopharyngeal carcinoma, an endoscopic examination is conducted where forceps are used to clip tissue for a pathological biopsy. The pathological biopsy determines whether it is definitively nasopharyngeal carcinoma and identifies the type of cancer cells, thus guiding clinical treatment.

Does nasopharyngeal carcinoma require surgery?

Nasopharyngeal carcinoma generally does not consider surgery. For most patients with nasal cancer, radiotherapy is the first choice, and depending on the different stages, it may be necessary to consider concurrent or adjuvant chemotherapy. The overall treatment plan primarily focuses on curative radiotherapy, and it also requires regular follow-ups to monitor recovery. If radiotherapy and chemotherapy fail or there is a recurrence, surgery may need to be considered in these cases, but the surgery is relatively difficult, and a detailed analysis of the patient's specific situation is required. Only a very small number of patients would be indicated for surgery.
