Shadow on the lung: What can be behind the frightening diagnosis

Usually it is discovered accidentally – for example, in the case of an x-Ray of the chest. But a shadow on the lung does not have to mean, as in the case of Jens Büchner, a bronchial carcinoma. Possible other causes, such as pneumonia or tuberculosis.

Lung cancer is the third most common cancer in Germany. Due to its unfavorable prognosis, he is by far the most common cause of death from cancer in men (with a share of 24 percent), and the second most common in women (15 percent). It is so hard to get him on the track, because there are no characteristic early symptoms or a meaningful Screening process. Therefore, the disease is usually discovered by chance during an x-ray examination of the lungs: Then round or oval changes in the lung tissue, so-called shadow on the lung. The higher the resolution of the CT-equipment is, the greater the probability that a shadow can be seen on the recordings.

A shadow on the lung does not automatically mean cancer

Each lung stove around the stove, or Tumor, as the shadow in the lung is called in technical language, is suspicious and needs to be clarified. Among the typical causes good diseases – such as malignant tumors, but also infections such as tuberculosis, connective tissue, tissue changes after an injury, fungal diseases, or parasites such as the Fox or dog tapeworm can be a trigger for cysts or car pile-immune diseases for the formation of cell.

To find out whether the tissue that was visible when x -, is benign or malignant, a Lung endoscopy (bronchoscopy). Ultimately, the probability that it is a single shadow of a lung cancer is 40 to 50 percent, depending on the age of the patient and the size of the rotary hearth. According to a study of the thorax clinic of Heidelberg, 1467 surgically removed lung were approximately 51 percent of the herds of vicious.

Doctors work as Profiler – smokers are particularly at risk

“Potential lung cancer or possible metastases should be identified as early as possible, to be able to treat you successfully,” says Thomas Voshaar by the Association of Pneumological clinics (VPK) and head physician at the lung centre at the Bethany hospital in Moers. In order to decide whether a biopsy is necessary, the doctor created a risk profile of the Concerned. The so-called risk of Malignancy is, not surprisingly, in heavy smokers higher than in non-smokers. A further factor is the appearance of the Rundherds. A irregular limited around the stove is a worse sign than one with a smooth edge.

Old x-rays to help in the clarification of

Helpful shots are a diagnosis of the older x-ray. “The patient can remain under certain circumstances, saves a lot,” says Robert Wurm of the Uniklink Graz (UKIM). Because a stove that has not changed its shape and size in two years is almost certainly benign. Most of the time he is observed in the following years. The progress of the disease, it comes to clarification.

Lung mirroring and punctuation to create clarity

The bronchoscopy is one of the most important studies. According to the lung mirroring the doctor knows, whether it is lung cancer and how the disease extended. It is the most important diagnostic measure for suspected lung cancer. With a bronchoscope – a flexible tube with a camera – can see the doctor, the bronchi and their branches, and tissue samples from the bronchial wall or enlarged lymph nodes.

He does not approach the suspicious tissue is punctured, the lungs by a long, thin needle through the skin of the chest into the lung is pierced. “This is not usually the removal is much more painful than a blood,” explains the cancer information service. A thin needle is inserted and tissue or cells is sucked in.

After the diagnosis

Little lungs are removed herds, usually through a key-hole operation. Only a few small incisions-rich, the Ribs must be spread apart. In the specialty hospitals, a pathologist examines the so-removed tissue on the spot so that the findings “may mean” to be directly operated.
