There are Other symptoms include a great pain in the chest, breathing is getting shorter, hoarseness, bloody sputum (fluid coughed up from the respiratory tract), and frequent sessions, bronchitis or pneumonia.
Sometimes the symptoms of lung cancer, bone pain, headache, dizziness or other signs of disease metastasis. Doctor suspected lung cancer using chest X-rays can find and display of lung cancer. CT scans, X-ray images of connected computers that can be used to find the approximate size and location of the tumor series. Further assessment of cancer cells, the doctor must examine them under a microscope. In a procedure called a biopsy, a doctor removes a small tissue sample from the tumor. Occasionally, microscopic analysis of sputum cells helps to confirm the diagnosis. Diagnostic technique known as the bronchoscope allows physicians visually examine the patient's bronchi. In this procedure, the doctor Bronchoscopes channel shows thin, light and magnifying optical devices, regardless of the patient's mouth and down the trachea and bronchi and lungs.
Bronchoscopes can be fitted with a small cutting tool, which allows doctors to obtain cell samples are examined under a microscope. Treatment depends on lung cancer, the size and location of the tumor-stage disease and the age and general health condition of the patient type. If there is no evidence that the disease is spread through the lung tumor can be removed using one of the many surgical procedures. At resection, only a small part of the lung was removed. The left lung has two chambers, the right lung, and three; to remove the entire lobe is called a lobotomy. Removing all the light is called light. After the surgery), radiotherapy and chemotherapy are (cancer drugs that are used to ensure that the entire tumor is removed. Unfortunately, less than 50 percent of patients with lung cancer are candidates for surgery because their cancer has spread to other parts of the body. Lung cancer patients should be monitored regularly after treatment, but there is still no sign of cancer. Other lung develops many dependents. Preliminary results of the studies, gene therapy, lung cancer, first described in 1996, it was found that the defective gene replacement of the normal p53 tumor suppressor gene p53 is reduced or suspended when the lung tumor growth. According to the American Cancer Society, 41 percent of diagnosed human lung cancer diagnosis within one year after implementation, only 14 percent stay for five years. If cancer is detected while still localized, the relative five-year survival is around 50 percent, but only 15 per cent of the lung showed that phase.
