symptoms of advanced lung cancer is not one personal, advanced lung cancer when the disease more serious, the need for timely symptomatic treatment of advanced lung cancer is, if the cancer cells invading the mediastinum, may occur The following symptoms, unfortunately, they appear to make relatively poor prognosis.
1, hoarse voice is one of the symptoms of advanced lung cancer
control function of the left recurrent laryngeal nerve pronunciation from the neck down to the chest, the heart of the great vessels to bypass the line back up to the throat, which dominated the left side of the vocal organs. thus, if the tumor invaded the left side of the mediastinum, the recurrent laryngeal nerve oppression, hoarseness have given rise to , but no sore throat and other symptoms of upper respiratory tract infection.
2, face, neck edema, symptoms of advanced lung cancer is more common
on the right side of the mediastinum vena cava, it will come from the upper limbs and head and neck venous transferred back to the heart. if the right mediastinal tumor invasion and oppression of the superior vena cava, jugular vein can first return to poor due to engorgement, and finally also cause the face, neck Department of edema, which requires timely diagnosis and treatment possible.
3, shortness of breath, pleural effusion is the performance of advanced lung cancer symptoms
the end, the regional spread of lung cancer occurred almost every varying degrees of shortness of breath. produced by the normal lung and cardiac tissue fluid from the thoracic lymph nodes back to the middle of the liquid. if these lymph nodes are tumor obstruction, the tissue fluid to accumulate in the pericardium to form the accumulation of pericardial effusion or pleural effusion in the pleural cavity formation. in both cases can cause shortness of breath. However, because many patients with various degree of smoking, chronic lung disease, identification of shortness of breath caused it to be difficult.
addition to still others because part of the lung cancer due to having lost respiratory function, so that is a respiratory dysfunction resulting from breathing discomfort, this discomfort at first only in the movement to end even when they feel the rest.
pain in patients with advanced lung cancer is often manifested symptoms of advanced lung cancer patients to why most would pain? pleural space is a very complex, three-quarters of lung surface area is the chest wall surrounded by a thin membrane which is (parietal pleura), fat, muscle, ribs and skin composed of different proportions. any part of the tumor invasion and above will cause pain. So much has happened within the regional broadcast chest of lung cancer patients had scattered the symptoms of chest pain. enveloping the top of the lung, the apex of the place, forming a specific area of the chest wall. from the neck, the dominant upper extremity sensory and motor nerve fibers through this region into the upper limb are . Therefore, if the tumor invasion to this area tend to be affected side of the upper extremity pain, weakness. sulcus lung cancer as an often shoulder the main symptoms. analgesics such pain often need to be alleviated. these are usually patients can easily be sent to a plastic surgeon or neurologist treatment, thus losing the chance of early diagnosis.
