What is a lung tumor?

Benign lung tumors arise from spontaneous neoplasm of the body's own tissue, occasionally triggered by inflammatory processes. The newly formed cells have often lost their specific function of the original tissue from which they originated, and are now nothing but space consuming.

Benign tumors do not affect a person's life. Unless they exert too much pressure on adjacent tissue due to their location, as may occur, for example, in the brain or in the trachea. They grow slowly, well demarcated from the rest of the tissue (usually encapsulated) and are usually confined to their place of origin. In the radiograph, they appear as so-called round herds.

Benign tumors make up about two percent of lung tumors. They can develop from all tissue types found in the lung: there are adenomas, lipomas, angiomas, fibroids, and chondromas. Hamartomas are most commonly found. Common to all benign tumors is a smooth surface and a soft, slidable texture against the neighboring tissue.

Benign (benign) tumors of the lung, as well as malignant tumors, are usually discovered by chance during x-ray examinations of the thorax.

Lung tumor prognosis

Affected patients usually have no complaints. However, if the benign tumor is located in the central airways, persistent cough with sputum or spitting blood may occur. Benign lung tumors become life-threatening when they relocate the trachea or press on vital arteries. This is very rare.

If the surgeon is able to completely remove the tumor, the prognosis is good. Benign lung tumors rarely recur, ie they usually do not come back. After surgery, the patient should go to check-ups (X-ray, pulmonary function test ) at regular intervals.

You can not take any special precautionary measures against benign lung tumors.

Every pulmonary fundus discovered in the X-ray image must be regarded as malignant until proven otherwise. Apart from a bronchial carcinoma or the metastasis of another primary tumor, infectious lung diseases (eg tuberculosis ) and - after injuries - traumatic changes (eg due to an encapsulated hematoma) can also be considered as the cause of around heart. To ensure the diagnosis, the attending physician will, if possible, also consult older X-rays. Because around hearth, which has not changed its shape and size in two years, is almost certainly benign.

If no older images are available for comparison, the patient is first subjected to computed tomography (CT). The statements of a computed tomogram regarding the good or malignancy (dignity) of a tumor, however, are not conclusive - they can only give a hint (see table).


Criteria for assessing the dignity of a pulmonary heart through CT

probably benign (benign) tumors probably malignant tumors calcification difficult to delineate (diffuse) cup-shaped coarsely speckled popcorn-like central difficult to distinguish (diffuse) rarely possibly eccentric (in scar carcinoma)contour smooth edges Milky glass opacity peripheral and blurred, bronchus or vessels included, thickened, radiating, lobulated with navel Wall thickness at the melting heart Wall thinner than 5mm Wall thicker than 15mm A reaction of the pleura(rib and lung skin)none Thickening confiscation Patient age ( smoker )<30 years> 50 years Patient age (non-smoker)<40 years> 50 years

Therefore, the doctor will additionally perform a bronchoscopy or (for tumors located outside the lung) a thoracotomy (surgical opening of the chest cavity). Both procedures serve to obtain samples for a microscopic tissue examination.

Lung tumor therapy

In most cases, a benign lung tumor is surgically removed. If surgery is not possible - whether because of the location of the tumor, the patient's state of health, or lack of consent - the tumor can also be laser ablated during bronchoscopy, if appropriate. Neither radiation nor chemotherapy is useful in benign lung tumors.
