Lung cancer is one of the common tumor diseases in our life. Today, I will give you some detailed knowledge about the symptoms of advanced lung cancer before death, the treatment of lung cancer is also a long-term arduous task and patients have to suffer a lot of pain in treatment. Lung cancer not only destroys the internal organs function of human body, but also destroys the immune function of human body, so that the Yin and Yang of human body are out of balance, resulting in the failure of internal organs function, which will lead to terminal symptoms of lung cancer, thus causing death. 1.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, while stomach, colon and esophagus cancer can bleed in stool. 2.Lumps are formed by malignant proliferation of cancer cells, which can be touched by hands on the surface or deep inside the body. 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 Patients with advanced lung cancer in which regional spread of pleural effusion occurs almost always 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. Hoarseness The recurrent laryngeal nerve, which controls the left side of the articulation function, travels down from the neck to the chest and returns up to the larynx around the large blood vessels of the heart, thus innervating the left side of the articulation organ. 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 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 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.Ulcer Formed by the rapid growth of cancer tissue and insufficient supply of nutrition in some body surface cancers, 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 complicated by infection. In addition, gastric and colon cancers can also form ulcers, which can usually be observed only through gastroscopy and colonoscopy.
