The first signs of lung cancer and their prevention

Lung cancer is one of the most common forms of cancer.About 12 million. People get sick this type of cancer each year.For most people, the cause of lung cancer is smoking.Cigarette smoking causes cancer in 9 of 10 cases.

first signs of lung cancer :

Less common symptoms of lung cancer include: hoarse voice, difficulty swallowing, swelling of the face caused by the blocking of the main blood vessel and swelling in the neck caused by enlarged lymph nodes.Constant pain in the chest, under the ribs on the right side should also alert the person.Cancer growing right on top of the lungs, called Pancoast tumor.The development of tumors can cause very specific symptoms.The first signs of lung cancer, namely Pancoast tumor, manifested in severe shoulder pain that spreads down the arm.

If any of the above symptoms, you should consult a physician who must assess the overall health and examine the patient.Most likely, your doctor will refer you to the hospital for x-rays to see any abnormal deviations in th

e lungs.Also, the patients received the standard blood tests.Patients suffering from wet cough, should be submitted sputum samples.The laboratory staff will examine the samples for the presence of cancer cells.Upon confirmation of the primary symptoms appointed bronchoscopy.This test is performed to inspect the inside of the airways.During the test, the doctor will inject a narrow, flexible tube (bronchoscope) into the throat, through all the respiratory tract.Usually, this test is performed on an outpatient basis under local anesthesia.The doctor will ask you not to eat or drink before the test.During bronchoscopy patient is lying on the couch, taking a sedative to relax.Shortly before the test, the nurse does an anesthetic on the back of the throat.Then the doctor inserts a long, thin, flexible tube into the mouth and carries them down the airway.During the procedure, the doctor may take tissue samples for testing.After bronchoscopy, you can not eat or drink anything until the local anesthetic does not stop its action.Numbness usually takes about an hour.

Computed tomography is usually given after bronchoscopy or biopsy.CT scans can show the area where the cancer develops.Snapshot allows the doctor to see any changes in the development of cells and to know exactly where these changes occur.On CT scans are also performed percutaneous lung biopsy.The doctor inserts a thin needle through the skin and muscles of the chest, to take samples of the tumor cells of the lungs.In fact, the biopsy takes only a few minutes, but the preparation can take anywhere from 30 minutes to an hour.Usually, this test is carried out in the X-ray department or a special room procedures oncology clinic.The doctor put a local anesthetic injection in the area where the needle will pierce skin.Once the needle will be in the light, the doctor uses ultrasound machine to make sure that the tip of the tumor.The physician then takes a sample of cells with a syringe.After the biopsy, the nurse will closely monitor you for a few hours.You may need to stay in hospital overnight.There is a small risk that may occur after the biopsy pneumothorax.If you encounter difficulties with the skin biopsy, the doctor may do an open lung biopsy under general anesthesia.
