Nodule on lungs also known as pulmonary nodule can be observed on the lung tissue with a simple Chest X ray examination. The nodule should have a minimum diameter of one centimeter to be recorded as a nodule. A lung nodule is usually not associated with any signs or symptoms and is often an incidental finding of a Chest X ray examination.
As per estimates about 150,000 cases of nodules on the lungs are detected incidentally each year in the United States. The treatment of the lung nodule depends upon the cause and is aimed at alleviating the symptoms of the condition.
What Can Cause Nodules On The Lungs?
There are a host of causes that are associated with the development of nodules on the lung. Also referred to as pulmonary nodules, some of the leading causes associated with lung nodules include,
- Neoplastic lesion which may be benign or malignant in nature. Lung cancer or metastatic lesions may be represented in the form of lung nodules. The tumor of the lymphoid tissue ( lymphoma) or connective tissue ( fibroma) or nervous tissue ( nerofibroma) etc. may be manifested in the form of nodules on the lungs.
- Infections or inflammatory lesions often caused due to mycobacterium tuberculosis may also be observed in the form of nodules on the lungs. These nodules caused due to inflammatory and infectious conditions are referred to as granulomas. Other infectious nodules can also be caused due to blastomycosis, nocardiosis, histoplasmosis, etc.
- Lung abscess or pneumonia may also be manifested in the form of lung nodules.
- Hydatid Cyst (i.e. a cyst form due to tapeworm infestation) can also be a cause of lung nodules.
- Rheumatoid arthritis and sarcodiosis are also other generalized disease conditions that may be associated with nodules in the lungs.
- Congenital anomalies are also responsible for nodules on the lung tissue. Mucoid impaction can also be manifested in the form of nodules on the lungs.
Symptoms And Treatment For Pulmonary Nodules
In most cases nodules on the lungs are incidental findings and are not associated with any symptoms. However symptoms may be present depending upon the cause for the formation of the lung nodule. The symptoms may include the following,
- Breathlessness or difficulty in breathing on the slightest exertion. This may be experienced especially in cases of multiple nodules and when the nodules result in obstruction of the air passage.
- Pleural Effusion or edema of the lung parenchyma may be observed in select individuals. The symptoms of lung edema may be observed in cases of inflammation and infection and also in cases of tumors.
Treatment For Lung Nodules
The treatment regimen for the management of nodules on lungs depends upon the case of the nodule. A follow up examination using X rays and CT scan imaging may help the physician ascertain the progress of the treatment schedule.
- Yoga exercises and deep breathing practice have been found to be beneficial in improving the capacity of the lungs and help alleviate the symptoms.
- Homeopathic Drugs like Lycopodium and Drosera are found to beneficial in the treatment of lung nodules associated with infectious or inflammatory condition.
- Anti Koch’s Treatment is recommended in cases of tuberculosis treatment.
