What are the dangers of nasopharyngeal cancer

Experts say that after contracting nasopharyngeal cancer, especially in the late stage, it will bring great harm to the patient's health. At this time, nasopharyngeal cancer will metastasize, and the main sites of metastasis are lymph nodes, lungs, liver, etc. Some patients may also have pelvic and limbs. In order to avoid the occurrence of these metastatic symptoms, early detection and early treatment must be done. So, what are the hazards of nasopharyngeal cancer?

First, NPC has a high metastasis rate. Recent studies have shown that the cumulative recurrence rate of NPC after radiotherapy is 25% and the metastasis rate is 22% in 5 years. How to reduce the recurrence rate and metastasis rate of NPC, and thus reduce the mortality rate, is the key to improving the survival rate of NPC patients. At present, surgery and radiotherapy can only kill cancer cells in the treatment of NPC metastasis, but they cause great damage to the patient's body and promote the spread and recurrence of cancer cells in a certain sense. Therefore, biological immunotherapy is more urgent and important.

Secondly, nasopharyngeal carcinoma metastasizes to lymph nodes. Lymph node metastasis: Cervical lymph nodes account for about 1/3 of the body's lymph nodes, especially deep lymph nodes, which are closely related to tumor metastasis. Nasopharyngeal carcinoma is characterized by early metastasis of cervical lymph nodes and a high metastasis rate. Metastatic lymph nodes are often multiple, hard masses of varying sizes. Generally, they grow from small to large as the disease progresses, and their number increases. They gradually merge into huge masses, and their mobility is gradually limited. Usually, the metastasis is from the upper neck to the lower neck. About half of the patients have bilateral neck metastasis, and preauricular lymph node metastasis is less common.

Then, the most frequent metastasis of NPC is distant metastasis. Distant metastasis: The distant metastasis rate of NPC is relatively high, which is obviously related to whether the primary tumor invades outside the nasopharynx, whether the cervical lymph nodes have metastasized, and the size and location. The distant metastasis rate is higher when the tumor invades the oropharynx or nasal cavity. The metastatic site can be single or multiple. Common distant metastasis sites are bones, lungs, and liver. Bone metastasis is more common in the spine, pelvis, and limbs. Metastasis to the chest, abdomen, mediastinal lymph nodes, inguinal lymph nodes, etc. can also occur. CT examination can detect metastasis to the kidneys, adrenal glands, and retroperitoneum at an early stage.

The above introduces the dangers of nasopharyngeal cancer. I believe everyone is already clear about it. Experts say that the incidence of nasopharyngeal cancer is getting higher and higher, so in life we ​​must do a good job of preventing nasopharyngeal cancer to reduce the incidence of the disease.
