What are the symptoms of lung cancer? Symptoms of lung cancer at different stages

The occurrence of lung cancer will bring great pain to everyone. Lung cancer is also divided into several stages, and the symptoms of each stage are also different. It is necessary for everyone to know what the symptoms of each stage are. The following experts will introduce what these symptoms are. The early symptoms of lung cancer include cough, hemoptysis, chest and back pain, wheezing and unexplained fever. Lung cancer is a malignant tumor that occurs in the respiratory organ lung, and the symptoms are closely related to the location where it occurs. Generally speaking, lung cancer is divided into central lung cancer and peripheral lung cancer. Central lung cancer generally presents symptoms slightly earlier because it occurs in the main bronchus, and cough, blood in sputum or chest discomfort appear earlier. Peripheral type may have chest pain changes when the tumor accumulates to the pleura when it is discovered. If it develops further, pleural lesions will occur, and pleural effusion will occur. In addition, arthritis will occur, often with clubbing. It manifests as migratory arthritis symptoms, burning pain in the elbows, knees, wrists, ankles, and metacarpophalangeal joints, and movement disorders. In general, cough is the easiest to be ignored among the early symptoms, because many bronchial diseases and lung diseases are manifested as cough in the early stage. Cough may be caused by colds or air pollution, but cough is also often one of the important symptoms of lung cancer, which must be made clear. The symptoms of advanced lung cancer are more obvious and complex than those of early lung cancer. The most common symptom is hoarseness. The main reason is that the tumor invades the left side of the mediastinum, compressing the recurrent laryngeal nerve, resulting in hoarseness, but without sore throat and other symptoms of upper respiratory tract infection. In addition, shortness of breath and pleural effusion are also one of the late symptoms of lung cancer. Almost all patients with advanced lung cancer with regional spread have shortness of breath to varying degrees. The lymph nodes are blocked by tumors, and these tissue fluids will accumulate in the pericardium to form pericardial effusions or accumulate in the chest cavity to form pleural effusions, resulting in shortness of breath. There is also edema of the face and neck. There is the superior vena cava on the right side of the mediastinum, which transports venous blood from the upper limbs and head and neck back to the heart. If the tumor invades the right side of the mediastinum and compresses the superior vena cava, the jugular vein will initially become distended due to poor reflux, and eventually the face and neck will edema, which requires timely diagnosis and treatment. The symptoms of lung cancer patients before death are basically all kinds of internal and external physiological manifestations caused by the lung cancer virus, which are in a prominent state. First, there is a mass, which is formed by the malignant proliferation of cancer cells. It can be touched on the surface or deep part of the body by hand. The metastasis of the tumor to the lymph nodes can cause lymph node enlargement. Some superficial lymph nodes, such as the cervical lymph nodes and axillary lymph nodes, are easy to touch. The second is pain. Severe pain is a symptom of lung cancer before death in the late stage. Pain is generally caused by cancer cells invading the nerves. Many people feel extremely painful in the late stage, and even taking medicine is useless. The third is ulcers, which are formed due to the rapid growth of cancerous tissues of some surface cancers, insufficient nutrition supply, and tissue necrosis. Bloody secretions are secreted, and there may be a foul smell when complicated by infection. In addition, gastric and colon cancers can also form ulcers, but they can generally only be observed through gastroscopy and colonoscopy. The last obvious symptom is bleeding, which is caused by cancer tissue invading blood vessels or rupture of small blood vessels in cancer tissue. For example, lung cancer patients may cough up blood and have blood in their sputum. If lung cancer is not treated and controlled in time, the above symptoms of late lung cancer will appear, making it unbearable for patients. After reading the above introduction, everyone knows the symptoms of lung cancer in different stages. I hope this will be helpful to everyone. In any case, avoid the occurrence of lung cancer in life and prevent it from invading our bodies. Take treatment measures immediately after getting sick to minimize the harm.
