What are the symptoms of advanced lung cancer?

summary

For lung cancer, we need to do a good job in the usual time to understand the relevant work, so that when we encounter this disease, we can understand the symptoms of advanced lung cancer, so that we can save a lot of trouble in the examination and treatment. So what are the symptoms of lung cancer? Experts introduce you.

What are the symptoms of advanced lung cancer?

Patients will have poor appetite, weight loss symptoms. Some lung cancer patients are as thin as a wood. With the progress of the disease, the respiratory function of lung cancer patients will also be damaged. Coupled with poor appetite, reduced food intake, patients' weight loss, weakness and other symptoms, the patients' physique will become worse and worse, and their ability to resist cancer will become weaker and weaker.

Lung cancer patients with severe lung injury, therefore, there will be very serious symptoms of dyspnea. At night, it's especially hard to sleep. Although advanced lung cancer is not infectious, it will affect the rest of patients. When breathing, absorb the air into the throat, like a blade, whistling the human respiratory organs. And cause severe pain in the lungs. This is the manifestation of lung cancer in its advanced stage.

Nausea and vomiting can also appear with the growth of tumor. Combined with dyspnea, lung pain, and chest pain, lung cancer patients will suffer a lot of physical pain. Surgery, chemotherapy and radiotherapy are the three traditional methods to treat tumors. However, with the development of medical technology, interventional therapy plays an increasingly important role in the treatment of tumors. Intra arterial drug infusion and intra-arterial chemoembolization are commonly used in interventional treatment of tumors.

matters needing attention

Intra arterial drug infusion: it puts a special catheter into the artery supplying the tumor, and then injects a certain amount of chemotherapy drugs to make it enter the tumor, kill the tumor cells, and achieve the purpose of treatment. Intra arterial chemoembolization: under fluoroscopic monitoring, a special catheter is put into the artery supplying the tumor to make its head end as close as possible to the tumor and avoid the artery supplying the normal tissue, and then the embolic substances mixed with chemotherapeutic drugs are injected. When these embolic substances enter the tumor, on the one hand, the blood vessels supplying the tumor cells are blocked, So that nutrients can not enter the tumor cells, to achieve the purpose of "starvation" of tumor cells. On the other hand, those chemotherapeutic drugs are released to kill tumor cells.
