Patients with advanced lung cancer often have obvious pre-terminal symptoms, which mainly include local advanced symptoms and extensive metastatic spread symptoms. The common pre-terminal symptoms include hoarseness, chest pain, shortness of breath, fever, coughing blood, etc., which bring great pain to patients. Generally speaking, the treatment of advanced lung cancer is also mainly focused on controlling symptoms to achieve the purpose of stabilizing the disease. When lung cancer patients reach the advanced stage, the cancer cells are spreading continuously. Many people have no idea about the survival situation of patients with advanced lung cancer, and because they do not know what are the terminal symptoms of advanced lung cancer, they do not take timely treatment measures even when they are critically ill, which causes lifelong regret. Lung cancer not only destroys the function of internal organs of human body, but also destroys the immune function of human body, so that the balance of Yin and Yang of human body is lost, resulting in the failure of internal organs, which will lead to terminal symptoms of lung cancer, thus causing death. Lumps: formed by malignant proliferation of cancer cells, which can be touched by hands on the surface or deep parts of the body. Cancer of thyroid, parotid gland or breast can be touched in shallower parts under the skin. Tumor metastasis to lymph nodes can lead to enlargement of lymph nodes. Certain superficial lymph nodes, such as cervical lymph nodes and axillary lymph, can be easily touched. 2.Pain: The appearance of 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. 3.Ulcer: Due to the rapid growth of cancer tissues in some body surface cancers, the supply of nutrition is insufficient and tissue necrosis occurs. For example, some breast cancers may have crater-like or cauliflower-like ulcers on the breast, secreting bloody secretions and having foul odor when infected. In addition, stomach and colon cancer can also form ulcers, which can generally be observed only through gastroscopy and colonoscopy. 4.Bleeding: It is produced by the invasion of blood vessels by cancer tissues or the rupture of small blood vessels of cancer tissues. For example, lung cancer patients can hemoptysis and blood in sputum; stomach, colon and esophagus cancer can bleed in stool. Late stage lung cancer will manifest as bleeding, and if the disease is not controlled all the time, there will be terminal symptoms of lung cancer, which makes lung cancer patients suffer and painful.
