1, shortness of breath, pleural effusion is lung cancer late symptoms in performance. The regional diffusion occur almost all of lung cancer patients had different degrees of shortness of breath. Produced by lung and myocardial ZuZhiYe chest is normal by the lymph node back to fluid. if these lymph node was tumor obstruction, these ZuZhiYe will will carry your formed within the pericardial pericardial effusion or will carry your pleural effusion in chest cavity forming. Above two kinds of circumstances which can lead to shortness of breath. However, for a lot of different degree of merger smoking patients, this to chronic lung disease identification of shortness of breath brings certain problems

In addition, because a department for a long lung tissue lose respiratory function a tumor, thus make is a respiratory function damaged and produce breath unwell, this kind of discomfort at first only in movement, the ultimate even produced when rest also feel.

2, husky is lung cancer late one of symptoms. Control the left the pronunciation function recurrent laryngeal god after neck, chest downward to the large vessels bypass heart return line up to the throat, which dominate the pronunciation organs left. Therefore, if the tumor invasion and mediastinal left, make the recurrent laryngeal nerve be oppressed, shrieked they generate, but no sore throat and upper respiratory tract infection other symptoms.three, face, neck edema is lung cancer late symptoms, the more common in mediastinum right have superior vena cava, it will come from the upper and ShuZhuan meaning dirty head venous blood. if the tumor invasion and mediastinal right oppression superior vena cava, may initially impeded and jugular vein engorgement because of backflow, finally will also lead to face, neck edema, this needs to be timely diagnosis and treatment.

4, lung cancer pain sorrow

Painful sadness is lung cancer late patients often has exhibited symptoms, lung cancer patients reached an advanced stage of why many painful sadness? The chest is a very complicated space, lung surface three-quarters of the area is chest wall around, it is by a thin layer of lining (parietal pleural), fat, muscle, ribs and skin composed of according to different proportion. Tumor invasion and above all can cause pain any department of grief. so most breast has occurred in patients with lung cancer spread of regional are symptoms of chest pain. around the top of the bag, namely pulmonary lung pointed place, formed a special area. Chest wall from the neck, dominate the flipper sensory and motor nerve fibers are through this area into the upper limbs. thus, if the tumor invasion thus area tend to be affected side upper limbs pain sadness, fatigue. This so-called “PanKe sandhust cancer”, or called as lung cancer on ditch cancer a often in shoulder pain as the main symptoms. This painful sadness is often need painkillers can be alleviated. Usually these patients were usually easy to plastic surgeon or neurologist processing, thus lost early diagnosis of opportunities.

On the above symptoms, severe impact of patients with lung cancer survival in patients with advanced cancer, especially the quality, physical pain sadness and psychological torture, can make the person on the weakness of the will and determination to beat the illness lose faith. so as to ease the symptoms may help patients not only physical condition improved, diseases can make patients more relief beat disease determination faith, actively cooperate with treatment, resulting in good therapeutic effect. but, at present surgery and chemotherapy treatment, patients are as essential stand chest pain, nausea, vomiting, hair loss, the lack of side effects. Suggest lung cancer late should adopt traditional Chinese medicine therapy, but fast relief to patients suffering so brimful of cancer cells, and fast growth, diffusion. until kill lesions cells.

Washington, Feb 27 : a study conducted by researchers from the U.S., Korea and Japan has found that acute viral infection is not a primary cause of acute exacerbation of idiopathic pulmonary fibrosis (IPF), a progressive, deadly disease resulting in thickening and scarring of the lungs.

Previous studies had suggested viral infection might cause exacerbation of IPF in a majority of patients who have the condition, which occurs most often in people between 50 and 70 years of age.”The etiology of acute exacerbation of IPF remains unknown, and occult viral infection has been proposed as one possible cause,” said Harold Collard, MD, director of the Interstitial Lung Disease Program at the University of California, San Francisco. “The results of this study suggest that the majority of cases of acute exacerbation of IPF are not due to viral infection.”IPF is thought to result from an abnormal fibroproliferative (scar-forming) response in the lung. as lung tissue becomes stiff and thick, lung function and breathing are impaired. In some patients, these changes occur gradually over time, while in others the condition may cause acute periods of severe worsening.In this study, the researchers enrolled 43 patients with acute exacerbation of IPF from two medical centers between 2006 and 2009. In addition, 69 patients with either stable IPF or acute lung injury (ALI) were enrolled from a single medical center as control subjects. In all cases, bronchoscopy was performed as part of patients’ clinical evaluations. Lung fluid and blood samples were collected and analyzed using three separate, highly sensitive viral DNA detection techniques to test for the presence of both known and unknown viruses.Results of these tests revealed evidence of viral infection in 33 percent of the patients with exacerbation of idiopathic pulmonary fibrosis patients, only four of whom had evidence of common respiratory viral infections. No viruses were detected in the lung fluid from stable patients.”The presence of respiratory viral infections in these four IPF patients suggests that a small minority of acute exacerbations of IPF may be caused by occult infection with common respiratory viruses,” said Dr. Collard, who is also an assistant clinical professor of medicine at UCSF.Unexpectedly, the researchers also found lung fluid samples from 28 percent of patients in the acute exacerbation group and 24 percent in the ALI control group tested positive for torque teno virus (TTV), a common virus that usually causes no symptoms in healthy individuals and which often appears in individuals with hepatitis. TTV was not found in stable IPF controls.Dr. Collard said the presence of TTV in the lung fluid of patients with acute exacerbation of IPF was unexpected and its significance is unclear.”The fact that a similar percentage of lung fluid samples from patients with ALI also were TTV positive suggests, however, that the presence of this virus may be a marker of lung injury but not causative,” he noted. “It will be important to clarify the role of TTV in acute exacerbation of IPF in future studies.”By more clearly defining the relationship between viral infection and acute exacerbation of IPF, Dr. Collard hopes this study will help focus future research on other possible causes of the condition.The findings were published online ahead of the print edition of the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
