What is a lung knot?

The lung node is the weight of the tissue located in the lungs. Although about 40% of these growths are benign, they may be cancer, especially in elderly and smokers. Many people with this condition have no symptoms, although some have wheezing, shortness of breath or persistent cough. Treatment depends on the size of growth, be it cancer and if it makes breathing more difficult for humans.

Although pulmonary nodes are generally quite common, certain types of people will get them more often than others. This includes people who are over 50, people who smoke, anyone with a family history of lung cancer and people who work with chemicals in their work. Non -non -lawn lung node may be caused by a number of conditions, including bacterial infections such as tuberculosis and histoplasmosis. Inflammatory diseases such as rheumatoid arthritis can also cause these growth, as well as some congenital defects, parasitiinfection C and tissue abnormalities such as lung cysts and hamartomas. Malignant nodes are most often caused by lung cancer, but may be soEarly caused by cancer somewhere else in the body: for example, breast cancer and colon cancer often spread to the lungs.

diagnosis

Since they often do not cause symptoms, most lung nodes are found when a person is administered by X -ray or computer tomography (CT) for another purpose. If the growth is small or the calcium seems to have in them, the healthcare provider generally recommends a vigilant waiting, especially if a person has no basic illnesses or other risk factors.

For those that are particularly large or have an asymmetric shape, they usually recommend a biopsy to see if they are cancer. This is usually done by accepting the sample of the cells in the pulmonary node either by performing a small cutter, or by running a thin, flexible tube through the mouth or nose, and then through the cells. After the biopsy is completed, the sample is examined under a microscope to diagnose.

Treatment and forecast

Benign lung node generally needs treatment only if it causes sufficiently serious symptoms to affect breathing. Health care providers usually treat the basic cause and then monitor growth to see if they are growing or becoming unusual. If a person is large enough to disrupt breathing, it will usually be surgically removed. Although the prognosis for benign nodes is usually good, their size and location can change.

Cancer nodes are generally surgically removed and can also be treated with chemotherapy or radiation. Like other types of lung cancer, survival rate in malignant nodes is very low, especially if cancer has spread to other parts of the body. This can be dramatically increased with rapid treatment, which is timely diagnosis very important.
