What is bronchoalveolar carcinoma?

Bronchoalveolar carcinoma (BAC), also referred to as bronchioalveolar carcinoma, is a rare type of lung cancer. It grows and spreads mostly in the walls of alveolar lung bags, without tending to metastasize to other parts of the body. Alveoles are small bags found in the final part of the lungs, where oxygen is usually replaced. This type of cancer is generally fatal and mortality is often high. The occurrence of bronchoalveolar cancer is often observed in non -smokers and middle -aged non -smokers, especially Asian origin. Examples of these substances are radon, naturally occurring radioactive gas and asbestos, mineral containing fibers that can penetrate deep into the lungs when inhaled. Asbestos has also been involved in many cases of mesothelioma, cancer that grows on the lining of Plica other organs due to asbestos exposure. Infections with certain viruses and bacteria can also lead to bronchoalveolar cancer.

cough is most closesta meal symptom of bronchoalveolar cancer. As cancer progresses, the cough can turn from mild into heavy and intensively violent, which can be accompanied by blood in sputum. Some patients also include weakness, anemia, seizures and vision changes. Other common manifestations of the disease include persistent chest pain, weight loss, shortness of breath and repeated lung infections such as bronchitis and pneumonia. Bronchitis is an inflammation of the airways mucous membranes and pneumonia is inflammation of the lung tissues.

During the early cancer phase, patients may not have any noticeable symptoms. Therefore, most of them are diagnosed at a later stage of the disease, resulting in delayed medical intervention. The diagnosis of bronchoalveolar cancer can be made using several diagnostic imaging tools. These include X -ray and computed tomography (CT) of the chest.

Possible alternatives of treatment for bronchoalveolar carcinoma are chemotherapy, radiation therapy and surgery. Surgery is often the possibility to removethe affected areas of the lungs. However, due to the aggressiveness of this type of cancer, it is often difficult to prevent new growth. It is also possible to consider lung transplantation to prolong life. Compared to other types of lung cancer, the survival of most patients with bronchoalveolar carcinoma in the late stage is generally poor.
