Lung Cancer: Symptoms and Diagnosis
The lung cancer is a disease that attacks the respiratory system of humans. More specifically and as I said the name of the disease affects the lungs to the organs that store the subject needs oxygen to breathe.
Some of the causes of cancer are smoking, prolonged exposure to carcinogens, genetic predisposition, smoking marijuana, sucking talcum powder, air pollution and excess or deficiency of vitamin A. These factors can lead to malignant cells individually. Anyway, in most cases it is a multiplicity of factors.
Those who have cough or pain in the chest area in addition to releasing blood from the mouth, snoring, having both face and swollen neck, feeling short of breath and make a whistle on your breathing will be eligible to receive adequate treatment for lung cancer .
Generally, the disease is detected when it is well advanced. The diagnostic methods used are radiologic studies, CT scans and positron emission tomography, magnetic resonance imaging, sputum cytology, bronchoscopy, mediastinoscopy, bone marrow biopsy and blood tests.
While lung cancer is treatable with surgery, chemotherapy and radiotherapy, only 15% of patients survive.

Diagnostic Of Lung Cancer Part 2
6. Cytology Sputum microscopy is examined a sample of sputum to see if it contains cancer cells. * Needle biopsy: A needle is inserted into the mass while the lungs are displayed on a computer tomograph. Then a sample of the mass and observed through a microscope for cancer cells.
7. Bronchoscopy: We introduce a flexible, lighted tube through the mouth into the bronchi. This procedure can help find tumors located centrally or obstructions in the lungs. Also be used to take biopsies or remove fluids to be examined with a microscope to see if they contain cancer cells.
Diagnostic Of Lung Cancer Part 1
A biopsy of lung tissue serves to confirm or refute a possible diagnosis of cancer as well as provide valuable information to determine the appropriate treatment.
If it is eventually detected lung cancer, additional tests will be conducted to determine how far the disease has spread, including:
1. Medical history and physical examination: The medical history was recorded risk factors and symptoms of the patient. The physical examination provides information about signs of lung cancer and other health problems.
Overview of Lung Cancer (II)
People who suffer
People over fifty years of age who have smoked cigarettes for many years.
The incidence of lung cancer among women in general has increased, which is clearly attributable to the increased number of women who smoke.
Symptoms
Cough or chest pain does not go away and may be accompanied by expectoration.
A whistle in breathing, shortness of breath.
Coughing or spitting up blood.
Hoarseness or swelling of the face and neck.
Design or feeling of breathlessness Read the rest of this entry »
Kinds of Lung Cancer Diagnostics
# Tests magnetic resonance imaging (MRI) uses powerful magnets and radio waves to make modern computers detailed cross-sectional images. These images are similar to those produced with computed tomography, but are even more accurate in detecting spread of lung cancer to the brain or spinal cord.
# The positron emission tomography (PET): Using a sensitive tracer of low dose that accumulates in cancerous tissues. Bone scans require the injection of a small amount of radioactive substance into a vein. This substance accumulates in abnormal areas of bone that may arise from the spread of cancer.
# Sputum cytology: is examined under the microscope a sample of phlegm to see if it contains cancer cells. * Needle biopsy: A needle is inserted into the mass while the lungs are displayed on a computer tomograph. After removing a sample of the mass and is seen through a microscope for cancer cells.

How to Diagnostics Lung Cancer?
Because lung cancer symptoms often do not manifest until the disease is advanced, only 15 percent of cases are detected in its early stages. Many lung cancer cases are diagnosed in early stage by accident, which means that are detected as a result of medical tests carried out due to other unrelated health problem.
A lung biopsy was used to confirm or refute a possible diagnosis of cancer as well as provide valuable information to determine the appropriate treatment. If it is eventually detected lung cancer, additional tests are carried out to determine how far the disease has spread, including:

Diagnosis and Treatments of Lung Cancer
Lung cancer diagnosis is made by radiological examinations: X-ray Computed Tomography and especially (or CAT scanner) Chest, and confirmed with a biopsy.
Only 15 to 20% of lung cancers are detected in its early stages because the symptoms are delayed. In many cases the diagnosis is usually incidental, that is, by medical evidence that you had another purpose. When diagnosed with lung cancer, additional tests are performed to evaluate different tumor stage (if the initial or advanced) as well as lung capacity and general condition.
Lung Cancer Tests
To determine if a patient has, in effect, of cancer, there is a wide variety of tests that the doctor can use. After the initial examination and x-ray, your doctor might order tests on phlegm. Other tests may include:
Bronchoscopy
It is a procedure designed to look inside the airways of the lungs. It involves inserting a thin, flexible tube down the throat into the airways. The tube allows the doctor to look inside. Your doctor might also take samples of tissues and cells (biopsy) during bronchoscopy.
Symptoms and Diagnosis Lung Cancer
Symptoms
Lung cancer tends to be very quiet, so that symptoms appear when the disease is at an advanced stage. These are:
* Chronic cough.
* Coughing up blood.
* Obstruction of the bronchi.

Lung Cancer Screening
If the diagnosis is cancer, your doctor will want to know the arena (stage or extent) of the disease. Staging was performed to determine whether the cancer has spread and, if so, to what parts of the body.
Lung cancer often spreads to the brain or bones. Knowing the stage (stage) of the disease helps the doctor plan lung cancer treatment. Some of the tests used to determine whether the cancer has spread are:
CT scans or CT scan. A computer linked to an X-ray machine creates a series of detailed pictures of areas inside the body.
MRI (magnetic resonance imaging). A powerful magnet linked to a computer produces detailed pictures of areas inside the body.
Radionuclide studies. The scans with radionuclides (radioactive isotopes) can show whether cancer has spread to other organs including the liver. The patient swallows or receives an injection of a mildly radioactive substance. A machine (scanner) measures and records the level of radioactivity in certain organs to reveal abnormal areas.
