Cancer is a group of diseases consisting of cell growth out of control. Lung cancer occurs when uncontrolled cell growth that begins in one or both lungs. The lungs were removed two large spongy organs in the chest cavity. The air is breathed into the trachea and moves down two tubes called bronchi, each going to a lung. Lung cancer occurs most often in adults aged between 40 and 70, have smoked cigarettes for at least 20 years.
More than 1,400 Victorians are diagnosed withyear. Only 2% of people with lung cancer that has spread to other parts of the body diagnosed live five years after diagnosis, although survival rates are at a very early stage, after being diagnosed with approximately 49% survive five years or more.
There are several types of lung cancer, depending on whether the cells are affected. The two most important are:
1. Small cell carcinoma
Approximately 15 percent are small cell carcinomas. This type of cancer spreadsThe beginning and shows few early symptoms.
2. Non-small cell lung cancer
These types of tumor cells, which are the main bronchi.
Some lung cancers are metastatic cancer in other parts of the body. The lungs are a common site for metastasis. Since lung cancer tends to spread or metastasis to treat very early in its course, is a life very dangerous for cancer and a tumor more difficult. While lung cancer can affect any organ in the body.
Symptomsvary, depending on where and how the tumor. Identify early signs of lung cancer are not always available or easy to use. Symptoms of lung cancer can take years to appear, is usually after the disease at an advanced stage.
Below you will find the following symptoms of lung cancer are:
1. Chest pain, shoulder or back of cough
2. A cough that will not go away or gets worse over time
3. Shortness of breath and difficulty swallowing
4. PlaintiffsPneumonia or chest infections
5. Wheezing or hoarseness may signal the block
6. Unexplained weight loss
Lung cancer is divided into phases according to their propagation. This helps doctors decide on appropriate treatment. Treatment depends on the type of cancer, age, health and other personal characteristics. Since there is usually not a single treatment of patients with cancer often a combination of therapies and palliative care. More than one type ofTherapy can be prescribed.
Although diagnostic techniques, important information, the extraction of cancer cells and looked under the microscope is the only way to diagnose lung cancer at all. This procedure is called a biopsy. If confirmed by biopsy, lung cancer, a pathologist, whether non-small cell or small cell.
NSCLC is in two phases, which reads:
1. At this stage of the tumor is confined to one lung and nearby lymph nodesNodes.
2. During the large, lung cancer other infection as well as other organs of the body.
For non-small cell lung cancer, these are called Phases I-IV. The lower numbers indicate earlier stages when the cancer is less common:
1. Phase I is when the cancer is found only in one lung and lymph nodes.
2. Phase II, when the cancer has spread to lymph nodes around the infected lung.
3. Phase III is when the cancer has spreadlymph nodes around the trachea, chest wall and diaphragm on the same side as the diseased lung.
4. Stage IV is when the cancer has spread to lymph nodes on the lung or other in the neck.
5. Stage IV is when the cancer has spread to the rest of the body and in other parts of the lung.
As with most cancers, the results are better when the cancer is diagnosed in its prenatal stage. However, some cases of lung cancer are not diagnosed until they are already well advanced. Treatment can thenLimited to alleviate the symptoms. Treatment decisions depend on whether SCLC or NSCLC. Treatment options include:
1. Chemotherapy is an anti-cancer drugs are given to stop cancer cells from multiplying too much. This treatment is more effective for small cell carcinoma.
2. Surgery to remove the affected part of the lung or an entire lung. This offers the best chance of cure if the cancer has not yet been distributed throughout the lung.
3. To address radiotherapy with X-rays to kill cancerCells. Can be used in a lung cancer early stage and stop the further spread of cancer in lymph nodes.
4. Targeted therapy with small molecules, often in tablet form, which can be used after chemotherapy.
5. Clinical trials is a participation in a clinical trial that may be offered to evaluate the safety and efficacy of new drugs.
Tumors, which are closely associated with certain behaviors that are the easiest to avoid. If you are a user of tobacco,leave may still suffer greatly reduce the chances are the cancer. The most important preventive measures you can take is to stop smoking. Many products, such as nicotine gum, nicotine spray, nicotine inhaler have been successfully used to stop people who try to smoke.
There are common causes of lung cancer:
1. A person who smokes more than a pack of cigarettes a day, has a 20-25 times greater risk than those who never smoked.
2. Cigar and pipe increasesthe risk of lung cancer, but not as much as smoking cigarettes.
3. Asbestos fibers are silicate fibers, which consist of a life in lung tissue after exposure to asbestos can. The workplace is a common source of exposure to asbestos fibers.
4. Radon is chemically inert, with a natural gas that a natural decay product of uranium. With approximately 12% of deaths caused by radon gas.
5. Air pollution from cars, industry and power plants can increase the likelihoodFor lung cancer in people exposed
Screening techniques have been developed for cancer in its early stages, so that treatment options are available. This type of tumor is detected in the later stages of the disease after they are widespread and are difficult to treat. Possible lung cancer screening test, analysis of sputum cells, examination of the bronchi in fiber and low-dose spiral CT scan.
Cancer and cancer therapies, a person may feel too tired toexercise. However, studies show that increased physical activity, the energy levels of a person who has cancer.
Regular exercise improves the functioning of the immune system and can increase survival in some cases. Goal of five to 20 minutes of moderate intensity exercise on most days of the week. But not without the knowledge and practice of medical support because inappropriate exercise may be harmful.
