If you’re told you have bronchial carcinoma, you’re probably very concerned. What does that mean?
Bronichial carcinoma: definition
Historically, bronchial carcinoma was the name given to the development of some types of lung cancer – those that develop in the bronchi (the largest airways of the lungs) and bronchioles.
Now this term is used interchangeably with lung cancer of all kinds. While the name bronchial carcinoma can sometimes be used in the old way, which refers to lung cancer that develops in the central airways instead of the periphery of the lung, it is most commonly used to describe any type or subtype of lung cancer.
Bronichial carcinoma: types
There are 2 main types of bronchial carcinoma:
- Small cell lung cancer: Small cell lung cancer is named after the appearance of cells under the microscope (small cells.) This type of cancer is present in about 15 percent of people with lung cancer.
- Non-small cell lung cancer: Non-small cell lung cancer accounts for about 80 percent of lung cancers and is further divided into adenocarcinoma, squamous cell carcinoma of the lung and large cell lung cancer.
Bronichial carcinoma: history
Over the years, the most common forms and locations of lung cancer have changed. In the past, the most common forms were squamous cell carcinoma (a type of non-small cell lung cancer) and small cell lung cancer (oat cell carcinoma).
Lung adenocarcinoma is currently the most common form of lung cancer.
It is believed that part of this change is related to the addition of filters to cigarettes. Instead of cancers such as squamous cell carcinoma and small cell lung cancer, which usually occur in the large airways of the lung, pulmonary adenocarcinoma often occurs in the distant airways in the periphery of the lung. It is believed that the addition of filters makes it possible to draw toxic chemicals in cigarette smoke further into the lungs. Of course, lung cancer affects non-smokers as well as people who smoke, and adenocarcinoma is the most common form of lung cancer among non-smokers.
Bronichial carcinoma: symptoms
As with all tumor-related diseases, the body also sends alarm signals in bronchial carcinoma. If they occur, a doctor should be consulted to gain confidence and possibly detect the cancer as early as possible. Often the suspicion is unfounded and the disease turns out to be harmless. However, you should consult a doctor if you experience any of the following symptoms: cough, especially smoker’s cough, which changes suddenly. Bronchitis that simply does not improve despite the use of medication. In case of shortness of breath, chest pain, severe weight loss and coughing up blood.
With the older definition of bronchial carcinoma, the symptoms are often associated with the growth of cancer in the large airways. As such, common symptoms of lung cancer may include:
- cough of blood
- Recurrent pneumonia due to airway obstruction by a tumor
- persistent cough
At present, pulmonary adenocarcinoma is the most common form of lung cancer with 40 to 50 percent of cases. These tumors grow in the periphery of the lungs rather than in the central airways such as the bronchi, and for this reason the typical symptoms mentioned above may not occur. The early symptoms of pulmonary adenocarcinoma may instead be signs such as:
- unexplained weight loss
- short breath, especially during exercise
