cancer lungs: 4 Mesotelioma Malignant

Bronchial adenoma is a small group of malignant neoplasms of low the agresifitas. Occur in the lower trachea or main bronchi. Two of the most important forms are bronchial carcinoid and rare silindroma. Bronchial carcinoid as small cell carcinoma, derived from cells of bronchial mucosa Kulchitsky. These tumors develop nearly 4% of all bronchial tumors. Can become real in adolescence until middle age (average age at diagnosis, 45 years), where the number of men and women are affected about the same lot. Signs and symptoms of bronchial obstruction such as chronic cough, haemoptysis, or pneumonitis are common. Bronchial carcinoid tumors like carcinoid of the small intestine. Some tumors secrete serotonin, 5-hydroxy tryptophan, and other biologic substances which generate a complex of symptoms known as carcinoid syndrome. The symptoms include a red face, bronchoconstriction, and wheezing, and diarrhea. Carcinoid tumors follow the course of the disease is relatively benign, and surgical resection is usually quite useful, given the survival rate 5 years, exceeding 90% of typical carcinoid.

Mesotelioma malignant tumor that is generally not of the pleura, where the majority of cases associated with exposure to an abscess. This exposure may be brief but usually the time between the exposure and clinical awitan is 25 years old. Malignant Mesotelioma very fierce and the survival of less than 1 year from the time of diagnosis.

Both primary sarcoma of lung and primary malignant melanoma both lungs are rare, but it is a form of lung cancer are very fierce. Usually the type of lung cancer is more of a metastasis from the primary tumor was diagnosed rather than a locus of primary tumors.

Finally, it must be remembered that the lung is more often a place as metastasis cancer than the location of primary malignant neoplasms. The lungs are often the place deposits of cancer cells from the secondary other organs, because microscopic tumor emboli are carried by the blood is usually caught in the capillary network of the lungs. Tumors carried by the lymph from the lower half of the body and the abdominal cavity can be detained while walking through the duct torasikus. Neoplasms that often lead to lung metastases, respectively from the most common carcinoma of the breast, gastrointestinal tract, female genital tract and kidney, melanoma and male genital cancers.
