A Brief Look at Two of the Most Common Types of Lung Cancer
Lung cancer is an unpredictable growth of malignant cells in either one or both lungs. These malignant cells don’t grow into healthy lung tissue and don’t perform the necessary functions of normal lung tissue. The cancer cells interfere with the functional breathing capacity of the patient and may cause death. Although it is a kind of cancer that usually develops slowly over a long period of time, it can often be identified in an early stage, before it causes any problems.
There are two types of lung cancer; adenocarcinoma and carcinoma. Adenocarcinomas are those cancers that start in the ducts of lung tissues (bronchi). The adenocarcinoma cells may grow and spread into the alveoli and alveolar regions of the lungs. The second type of lung cancer is that of carcinomas, which begin in the respiratory tissue and the alveoli.
An imaging test called chest radiography can be used to identify these two types. Chest radiography is done to get a more detailed picture of the lungs. During a chest x-ray, a doctor will take images of the lungs’ interior structures. Two types of imaging tests are applied to determine lung cancer: Computed Tomography (CT) Scanning and Radiographic Imaging.
Both of these imaging tests will help doctors differentiate between benign and malignant lung tumors. If there is doubt as to whether or not lung tumors are benign, doctors may choose to treat cancer in an attempt to remove only the benign tumors. However, this will depend on the extent of cancer.
As already mentioned, there are two main types of lung cancer; pleural mesothelioma and adenocarcinoma. Pleural mesothelioma is caused by malignant cells that have spread from other parts of the body to the lining of the chest wall cavities. On the other hand, adenocarcinoma is a result of malignant cells that have spread from the lungs or bronchioles to the lining of the abdomen. Many times, adenocarcinomas will not produce any pain or other symptoms, making it difficult to differentiate them from pleural mesotheliomas.
Malignant cells begin to spread into the lungs when they spread through the lymph nodes and into the pleura. When cancer spreads to these areas, the symptoms will usually appear. The first sign of cancer will be difficulty breathing. The cancers will continue to spread until they reach the vital organs, where they then begin to produce chronic symptoms.
There are several ways for cancer to start in the lungs. These include exposure to asbestos, which was commonly found in the workplace and many of the patients with this type of cancer did not realize they had been exposed. Asbestos is linked to serious health issues including asbestosis and cancer. Unfortunately, there were no measures in place to detect this substance when it was being used, so many people who worked with asbestos continued to work with poor safety practices, allowing these toxic gases to enter their lungs and cause cancer.
Lung cancer can be difficult to treat if it has spread to other parts of your body. If it has spread to your lymph nodes, you may not be able to remove all of it. However, even if you cannot remove all of it, you can reduce its severity and discomfort. Treatment options include chemotherapy, radiation, and surgical removal of cancerous cells. Knowing the main types of lung tumors will help you to identify them when you are experiencing any of the symptoms.
The two main types of cancer that affect the lungs are pleural mesothelioma and adenocarcinoma of the lungs. Pleural mesothelioma is linked to chronic coughing and difficulty breathing while adenocarcinoma of the lungs is linked to tissue damage that causes the lining of the lungs to deteriorate over a long period of time. While most symptoms of these two different types of lung cancer do not appear immediately, if left untreated, these two tumors can grow large enough to block the airways through which air is taken in and out of the lungs. Untreated adenocarcinoma of the lungs can develop into cancer of the liver or bones, which can affect the quality of life.
When non-small cell cancer takes root in the lungs, it is usually referred to as either non-sclerotic and SCLC or smooth. Non-sclerotic lung cancers are mostly caused by smoking cigarettes and other tobacco products. Smooth cell lung cancers are mainly caused by asbestos exposure. Smokers are more at risk of both types of non-sclerotic lung cancer than non-smokers.
Two of the most common types of lung cancer are pleural mesothelioma and adenocarcinoma of the lungs. These two are the most common types of cancer of the lungs in men. There are different types of treatment for each one. Surgery can be used to remove parts of the affected tissue or it can involve the use of chemotherapy or radiation therapy. Smokers should also see a doctor soon if they have any of these symptoms because it may be non-cancerous and able to be treated easily.
