What are the phases of lung cancer progression?
lung cancer is a devastating disease that is one of the most common forms of cancer. Estimates from 2010 only on lung cancer in the United States indicate that 222,520 new cases will occur and 157,300 deaths will be attributed to disease annually. Understanding the progression of lung cancer is an important part of learning about the disease.
It is important to understand that there are several types of lung cancer. Lung cancer with small cells is often associated with smoking and includes small cells that grow rapidly to form large tumors. Lung cancer, which forms most of the cases, comes in four main types: spinocellular cancer carcinoma, which creates tumors in bronchial tubes; adenocarcinoma that affects the mucosal glands; bronchioalveolar, which causes air tumors; and undifferentiated carcinoma with large cells that tend to attack the outer surface of the lungs. If the tumor exists only in one Plicea area, the area is said to be at a limited stage. Tumors or cancer cells in the lungsEmi or other bodies testify to a large stage. Treatment options and prognosis will vary depending on phase and the amount of spread.
Most medical experts divide the progression of lung cancer in a monster into four different phases with several other partial stages. In the first phase, the tumor is less than 3 centimeters across and has not attacked lymph nodes or other organs. The second phase occurs when the cells reach lymph nodes, or attacked bronchus or grow with lung lung. In the third phase, the tumor may be larger or has grown to several tumors in one lung lobe. The fourth phase occurs when cancer metastasizes and attacked other organs in the body, including the brain or liver.
Analysis of lung cancer progression is usually monitored through ular regest. Some of the tests that the doctor can use to check the progression of lung cancer include computer topomography (CT) scanning, magneTical resonance tests (MRI) or bone scanning. These can show the level of invasiveness as well as early symptoms of metastatic growth. Symptoms of lung cancer progression may show that treatment does not work and may require a different approach.
symptoms associated with lung cancer progression include increasing respiratory problems. Chest pain, bloody cough and shortness of breath are common symptoms. In addition, patients can undergo pulmonary infections and pneumonia and must take special measures to avoid disease.
There are lung cancer treatment that can be successful in stopping the disease. Common methods of attacking the disease include chemotherapy, radiation and surgery. In general, the sooner the cancer is, the more effective the treatment. Doctors may also be able to prescribe medicines to express the symptoms associated with lung cancer progression.
