Lung cancer and says:
With 164,000 new cases are diagnosed in the United States and 20,600 new cases each year in Canada, lung cancer is the third most common cancer in North America. Although under the prostate and breast cancer is on the prevalence of lung cancer is the leading cause of cancer death in the United States and Canada. United States, an amount of five-year survival rate for lung cancer is relatively low at 14 percent, and the number rose to 50 percent if the cancer is detected early.
The main risk factor for lung cancer is smoking, the behavior to give 85 to 90 percent of all cases. Prolonged exposure to tobacco smoke also causes lung cancer. The main risk factors are related to chemical carcinogens in the workplace, especially asbestos and organic chemicals such as vinyl chloride. Exposure to radon and other pollutants also increases the risk of lung cancer, especially among smokers.
Oxygenated blood passes through a series of pipes and ducts in the lungs. It is divided into so-called respiratory bronchioles is called into smaller branches. At the end of the bronchioles are tiny air sacs called alveoli. Most cancer starts in the mucosa of the respiratory tract cancer, but may also in the trachea, bronchi, alveoli or start. About 20 percent of lung cancer patients had small cell carcinoma; lung cancer usually begins around the airways. Squalors carcinoma is often in the vicinity of the bronchi. It contributes about 30 percent of all lung cancer.
Lung cancer is often taken into account in the early stages. Patients develop a cough or a finding that the aggravation of the chronic cough. Other symptoms include chest pain, shortness of breath, hoarseness, coughing up blood. From the respiratory tract fluids and frequent bouts of bronchitis or pneumonia sometimes, early symptoms of lung cancer bone pain, headache, dizziness and other symptoms of diseases that have metastasized.
People with early warning signs should see your doctor to evaluate the symptoms and refer patients to doctors who specialize in cancer. A doctor will find out once the explore present complaints, history, illness, and family members with cancer. The method in the physical examination depends on the clinical symptoms and may be a rectal examination, where doctors use a gloved finger to gently check the smoothness of the bowel wall. Doctors can breast-exams for women who feel their breasts soft mass or tumor is carried out not investigated unusual.
During the test, your doctor can look for a thin tube called an endoscope to radiant tumor in the inner cavity of the body. Endoscopic procedures are inspected according to the organ or body cavity. Gastrointestinal Endoscopy, feeds the doctor a special endoscope in the neck, in order to examine the layers of the esophagus, the stomach and the first part of the small intestine. Colonoscopy uses a long flexible instrument for displaying the entire length of the colon.
A series of laboratory tests can help diagnose. In a Pap test, the cells lining the uterus are removed with a plastic brush. These cells under a microscope for abnormal cells that show signs that the cancer can develop, as well as signs of malignancy are investigated. If the clinical signs suggest that patients with colorectal cancer, doctors may be found in the occult blood in the stool. A small sample of stool on the patient card with a chemical called guaiacum, spread the coating reacts with blood. Letters were analyzed in the laboratory of the occult (hidden) blood. Further testing for signs of cancer chemicals in higher concentrations of certain types of cancer, if any. For example, measures prostate specific antigen (PSA) the level of prostate-specific antigen in the blood.
These
include computed tomography (CT) and magnetic resonance imaging (MRI). CT
and MRI use a computer to generate three-dimensional images of the tumor and
surrounding tissue. X-ray
mammography as a breast imaging allows doctors to detect and evaluate breast
cancer. High
frequency ultrasonic sound waves bouncing off the tumor and the surrounding
tissue to create an image of the tumor. Multimodal
visualization technique combining images from multiple imaging devices in a
single image what. The latest three-dimensional images in detail Computer
Aided Diagnosis analyze using sophisticated artificial intelligence computer
programming technology, x-rays and mammograms help call look for signs of
cancer and provides an automatic second opinion.
