Lung cancer is one of the common tumor diseases in our life. Today, we will give you some detailed knowledge about the symptoms of lung cancer before death in the late stage. Lung cancer not only destroys the internal organs function of human body, but also destroys the immune function of human body, which causes the loss of balance of yin and yang of human body, resulting in the failure of internal organs function, which will lead to the terminal symptoms of lung cancer, thus causing death. 1.Bleeding is produced by the invasion of blood vessels by cancer tissue or the rupture of small blood vessels of cancer tissue. For example, lung cancer patients can hemoptysis and blood in sputum; stomach, colon and esophagus cancer can blood in stool. 2.Lumps formed by malignant proliferation of cancer cells can be touched by hands on the body surface or in the deep. Cancer of thyroid, parotid gland or breast can be touched in the superficial part under the skin. Tumor metastasis to lymph nodes can lead to enlarged lymph nodes, and certain superficial lymph nodes, such as cervical lymph nodes and axillary lymph, can be easily touched. 3.Shortness of breath Pleural effusion occurs in advanced lung cancer patients with regional spread almost all have different degrees of shortness of breath. Normal tissue fluid produced by the lung and heart muscle is returned by the lymph nodes in the middle of the chest. If these lymph nodes are blocked by the tumor, this tissue fluid will accumulate in the pericardium to form a pericardial effusion or in the thorax to form a pleural effusion. Both of the above conditions can lead to shortness of breath. 4.Hypopnea is caused by the laryngeal nerve which controls the left side of the articulation function. Therefore, if the tumor invades the left side of the mediastinum, the laryngeal nerve will be compressed and hoarseness will arise, but there is no sore throat or other symptoms of upper respiratory tract infection. 5. Pain often indicates that the cancer has entered the middle or late stage. At first, it is mostly a vague or dull pain, which is obvious at night. Later on, it gradually worsens and becomes unbearable, day and night. Severe pain is a terminal symptom of advanced lung cancer, if it occurs, it is usually controlled by drugs. Pain is usually caused by cancer cells invading nerves. Many people will feel unbearable pain in the late stage, and even taking medicine does not work. 6. Ulcers are formed due to the rapid growth of cancer tissues in some body surface cancers and insufficient supply of nutrients, resulting in tissue necrosis. For example, some breast cancers may have crater-like or cauliflower-like ulcers in the breast, which secrete bloody secretions and may have foul odor when infected. In addition, gastric and colon cancers can also form ulcers, which can usually be observed only through gastroscopy and colonoscopy.
