Is it dangerous to have nasopharyngeal cancer?

Many cases show that in the late stage of nasopharyngeal cancer, the symptoms will move to the liver, lungs, bones and other parts. It will seriously endanger human life, and humans will lack passion for life and lose confidence in the future. So what are the hazards of nasopharyngeal cancer?

The harm of this disease is mainly achieved through different infection routes, mainly the following three routes:

1. Direct extension: The malignant tissue can invade and destroy the skull base bones by spreading upwards, with the oval foramen being the most common site. In the late stage, it can destroy the sella turcica and invade the II to VI intracranial signals through the foramen rupture, causing corresponding symptoms. The malignant tissue can invade the oropharynx, palatine tonsils and tongue root, invade the nasal cavity and eye sockets forward, invade the cervical spine backwards, and invade the Eustachian tube to the middle ear laterally.

2. Lymphatic migration: There are abundant lymphatic vessels in the lamina propria of the nasopharyngeal mucosa, so lymphatic migration can occur in the early stages of this cancer. About half of nasopharyngeal cancer patients go to the clinic with swollen neck lymphatic system. It first migrates to the posterior pharyngeal wall lymphatic system, then to the deep neck and other neck lymphatic systems, and rarely to the superficial neck lymphatic system. The neck lymphatic system usually migrates to the same side, then bilaterally, and rarely to the opposite side.

3. Blood flow: It often moves to the liver, lungs, bones, and then to the kidneys, adrenal glands, and pancreas.

According to the unified classification of China, the pathological structural types of NPC are divided into undecomposed low-grade cancer, decomposed cancer (including large round cell carcinoma, pleomorphic cell carcinoma, spindle cell carcinoma and mixed cell carcinoma, etc.) and highly decomposed cancer (including squamous cell carcinoma, grade I and II adenocarcinoma, etc.). The classification of the World Health Organization is keratinizing squamous cell carcinoma, non-keratinizing squamous cell carcinoma and undecomposed cancer.
