While spitting blood Amartiad this is hemoptysis, and this blood is derived from the lungs or the airways as a result of pulmonary hemorrhage, or bleeding in the airways. Hemoptysis is classified based nonmassive or on the size of a large loss of blood, but there are no standard definitions for these categories. In this article, is hemoptysis if nonmassive if blood loss is less than 200 ml per day. Lungs receive blood from the pulmonary arterial system and the airways. Low-pressure pulmonary system causes production of small volume hemoptysis while bleeding from the bronchial system, which is the pressure in the systemic, causing profuse expectoration of blood.

In general there are three types of mesothelioma that affect different parts of the body are pleural mesothelioma, which affects the lungs and pericardial mesothelioma, which affects the heart and peritoneal mesothelioma, which occurs in the abdomen. Hemoptysis and presents mainly with pleural mesothelioma, or in the lungs.

Exposure to various environmental factors Awaltard to other elements such as arsenic or asbestos increases the risk of injury jet of blood and bronchial tumors, although slow tumor growth and proliferation and may present with bleeding in some cases over many years. Malignant tumors in general have become especially Adenocarcinomas can stimulate clotting condition which increases the risk of injury Balnsdd pneumonia. It is permissible for a date, a chronic purulent sputum production, frequent respiratory infections including tuberculosis represent bronchiectasis. Association had hemoptysis with what is known as menstruation or menstrual blood jet.

The widespread use of products manufactured from asbestos lingers in the memory are the effects of exposure to these products for humans and devastating asbestos airborne particles more clearly. Will be diagnosed with the relationship between the widespread use of asbestos at the time, the metal looks simple and durable, will mean more people with mesothelioma over time. Between the use of a wide range of products and reach a period of latency in some cases to more than forty years.

After exposure to metal particles may be asbstos are hanging on the lungs and remain so for several decades. With pleural mesothelioma and molecules instigate cellular chain reaction causing the pleura or lining of the lungs to become cancerous. If not detected early or left untreated may develop into malignant mesothelioma to other stages of the disease.

Air travels to the lungs through the trachea through the airways. In the bronchi, the air shall be published to the smallest bronchioles, ending in the alveoli, which are surrounded by blood vessels. And is divided into air or oxygen to the waste. Is absorbed in the blood and oxygen out of waste or carbon dioxide exhaled.

Hemoptysis can be caused by coughing, even if slight cause shortness of breath, this is an indicator of more severe case of basic health issue. As the other early symptoms of mesothelioma cancer present, including shortness of breath and chest pains, cough, hemoptysis may begin slowly and irregularly. But should not a little bit of blood in the mucus expectorated be ignored or not care.

As if the discovery of hemoptysis in the early treatment could have been slightly to prevent the development of major hemoptysis. However, with pleural mesothelioma can be a huge hemoptysis reference to carcinogenesis and the beginning of the rapid spread of the disease and turning healthy cells into cancer cells.

Asbestos products have all been completed did not keep anything of it, but the damage is caused by the devastating. Significant rise in cases of mesothelioma is stunning, but were not surprising given the latency period associated with the disease, which sometimes exceed forty years this side of the widespread use of asbestos products in the same time.

Causes of hemoptysis
Lung cancer accounts for 25 percent of cases of hemoptysis in the United States. Bronchial cancer is a disease common lung cancer responsible for hemoptysis in 10 to 45 percent of all cases. But bleeding from benign or malignant tumors can be secondary to superficial mucosal invasion and erosion of the blood vessels or vascular lesions to a large extent. Breast cancer, kidney and colon cancer are more susceptible to lung Anbthat However metastatic lung cancer and rarely leads to bleeding.

Respiratory tract infection is the most common cause of hemoptysis and represents between 60 to 70% of the total cases. This infection causes inflammation of the mucous membrane surface and edema that can lead to rupture of superficial blood vessels. And pneumonia resulting from inpatient and outpatient hemoptysis in the United States, bronchitis caused nearly 27 percent of TB cases and accounted for 8 percent.

In the percentage of more than 35% have reason not known from patients with hemoptysis, and can be found on the cause identified after careful evaluation and diagnosis of hemoptysis of unknown etiology usually good and the majority of patients with resolution of bleeding within six months of the evaluation. But said the results of a study conducted on 13 patients were found to increase the incidence of lung cancer in smokers older or over 40 years with idiopathic hemoptysis and noted this study suggests that these patients need constant monitoring.

High blood pressure, pulmonary venous
Conditions that lead to high blood pressure, heart and blood vessels can cause hemoptysis in the heart. The most common of these is the heart systolic left ventricular failure. And unites other causes include heart and blood vessels mitral stenosis and severe pulmonary embolism. Although hemoptysis is recognized that the reason for the symptoms of pulmonary embolism, pulmonary embolism is a common cause of hemoptysis.

Hemoptysis in children
Respiratory infection is the leading cause of hemoptysis in children. The second most common reason among children is a foreign body aspiration with most cases occurring in children under the age of four years. There is another important reason is the expansion of stalks, which are often secondary to cystic fibrosis. And primary pulmonary tuberculosis is a rare cause may occur in less than 1 percent of cases. There is another reason is the trauma that lead to hemoptysis secondary to pulmonary contusion and bleeding.
