Remind lung cancer patients: Active treatment is required after discovering the disease, otherwise it is easy to be attacked by 5 kinds of complications

Lung cancer must have been heard by everyone. It is the malignant tumor with the fastest increasing incidence and mortality in China!

　　Relevant research surveys show that nearly 800,000 new lung cancer patients are diagnosed in China every year, and 700,000 patients die from lung cancer . Thus, the overall prognosis of lung cancer is not ideal.

　　Many people blame the death of cancer patients on the malignant tumor itself. But in fact, the death of cancer patients is not due to cancer cells and the tumor itself.

　　Instead, the malignant tumor continues to develop, overdrawing the nutrients in the patient's body, leading to organ failure and various complications . The vast majority of patients eventually died, in fact, died of these two factors. So the question is, what complications will occur when lung cancer continues to develop?

1. Infection

　　This situation mostly occurs in patients with central lung cancer, because the cancer cells continue to divide and proliferate, so the cancer continues to grow. These growing tumors often form an obstructive segment, or block the opening of the bronchus , causing corresponding lobe and segmental obstructive pneumonia , or cause atelectasis, which in turn leads to infection, fever and other problems;

2. Severe chest pain

　　With the continuous development of lung tumors, cancer cells will infiltrate into surrounding tissues, especially in areas such as the pleura and chest wall , which may cause pleural pain . This pain initially presents as intermittent sharp pain . Uncontrolled and constant drilling pain may occur in persistent development , which is often difficult to relieve with common pain relievers;

　　3. Pleural effusion

Nearly 38-53%　　of the causes of malignant pleural effusion are related to lung cancer. The most common pathogenic factor is the continuous development of cancer cells, which have invaded the parietal and visceral pleura and formed cancer metastasis. These metastatic cancer cells damage capillaries , causing fluid and blood to leak into the chest cavity, eventually forming a bloody pleural effusion.

　　In addition, factors such as lymphatic system drainage disorder, a large amount of protein in tumor cells entering the pleural cavity, and increased pleural permeability are also the reasons for the appearance of malignant pleural effusion;

　　4. Pulmonary bone and joint hyperplasia

　　The common clinical manifestation of this condition is clubbing, which can appear on the fingers or on the toes. Nearly 29% of lung cancer patients have clubbed fingers , especially those with squamous cell carcinoma.

　　In addition, nearly 1-10% of patients with adenocarcinoma also have proliferative osteoarthropathy . So far, the cause of bone and joint hyperplasia caused by lung cancer has not been fully clarified , which may be related to estrogen, growth hormone, nerve function , etc.;

5. Cardiovascular disease

　　A large number of research investigations have shown that no matter what type of lung cancer occurs in the patient, it may be combined with abnormal blood coagulation mechanism, that is, excessive blood coagulation. Patients may develop migratory venous thrombosis, phlebitis, and nonbacterial thromboembolic endocarditis, even months before the patient's lung cancer diagnosis.

　　All in all, during the development stage of lung cancer, multiple complications may occur, which involve the cardiovascular and cerebrovascular system, bone and joint system, respiratory system, chest tissue and other aspects. And where the cancer cells of lung cancer metastasize, which organ dysfunction may be caused.

　　Therefore, lung cancer patients should be vigilant and cooperate with doctors for active treatment. The possibility of complications can be reduced only if the lung cancer condition is controlled and stabilized.
