What are the causes of bleeding after treatment of nasopharyngeal carcinoma? What is the health care knowledge?

We usually ignore some minor problems until the disease becomes life-threatening. So, what is the cause of bleeding after nasopharyngeal cancer treatment? What is the health care knowledge?

What is the cause of bleeding after nasopharyngeal carcinoma treatment?

1. Recurrence of nasopharyngeal carcinoma: Recurrence of nasopharyngeal carcinoma can cause bleeding because the cancer continues to grow and invade the fragile blood vessels in the nasal cavity. If touched or rubbed by airflow, the blood vessels may rupture and bleed.

2. Side effects of radiotherapy: High-dose radiotherapy not only kills or kills cancer cells, but also damages normal cells, leading to necrosis of the nasopharyngeal mucosa, difficulty in tissue repair, long-term formation of ulcers, exposure of the main pharyngeal blood vessels, and hardening of the vessel walls. After radiotherapy, the tumor regresses and collapses, and the blood vessel walls cannot be effectively repaired, leading to blood vessel rupture and bleeding.

3. Pathological changes in blood vessels: Pathological changes in blood vessels on the surface of the nasopharynx are also a cause of bleeding. Studies have found that due to the long-term compression of nasopharyngeal blood vessels by cancer, microvessels will proliferate, become varicose, and twisted, resulting in uneven thickness of blood vessel walls, which are prone to damage and bleeding.

4. Nasopharyngeal tissue biopsy: Nasopharyngeal tissue biopsy is the direct cause of nosebleeds. If the biopsy accidentally damages the blood vessels, it may cause bleeding.

5. The age and tumor stage of NPC patients are also closely related to NPC bleeding. The older the age and the later the stage of the disease, the greater the possibility of bleeding.

What are the health care common sense for nasopharyngeal cancer?

1. Pay attention to climate changes, prevent colds, maintain nasopharyngeal hygiene, and avoid viral infections.

2. Try to avoid harmful fumes from smoking, such as kerosene lamps, pesticides, etc., and actively quit smoking and drinking.

3. If you have nasopharyngeal diseases, you should seek medical attention as soon as possible. If you find blood in your nasal discharge or spit out blood in your nasal discharge after sniffing, swollen lymph nodes in the neck, effusion in the middle ear, and other unexplained causes, you should have a detailed examination in time.

Through the above introduction to the causes of bleeding after nasopharyngeal carcinoma treatment and medical care knowledge, we all understand the treatment of nasopharyngeal carcinoma, distinguish the causes, and then treat them symptomatically.
