What are the symptoms of early stage lung cancer? How to detect it in early stage? These points can help you stay away from cancer

Lung cancer is a malignant tumor that originates from the epithelium of bronchial tubes and alveoli. So far, the cause of lung cancer is not very clear, but it is directly related to smoking, air pollution, chronic lung diseases, occupational factors and hereditary factors.

Lung cancer is categorized into central, peripheral and diffuse lung cancer according to the site of development.

The anatomical parts of the lungs are normally divided into the main bronchus, and then the lobes and lung segments below. Generally, central lung cancer is the lung cancer that occurs in the lesions above the lung segments, while peripheral lung cancer is the lung cancer that occurs in the lesions below the lung segments, which is divided according to the lesions.

Small cell lung cancer and non-small cell lung cancer are categorized according to pathological types. Small cell lung cancer accounts for about 15%, while non-small cell lung cancer accounts for 85%, but non-small cell lung cancer is also categorized into adenocarcinoma, squamous carcinoma and large cell carcinoma, etc.

Early stage lung cancer is the most common type of lung cancer.

Early lung cancer usually has no special symptoms, especially in some peripheral lesions of the lungs, but if lung cancer latent to a certain stage, it will cause coughing, coughing up sputum, and sputum with blood, etc.

Especially in some peripheral lesions of the lungs, lung cancer will cause coughing, coughing up sputum, and sputum with blood.

Especially for unexplained cough, persistent irritating cough, and even blood in sputum. Be sure to pay attention, it may be a manifestation of lung cancer.

As the disease progresses, if it is relatively large later, it can block the bronchial tubes, causing pulmonary atelectasis, and the patient will have the feeling of chest tightness and shortness of breath.

Then if the disease develops to the localized progressive stage, after the middle and late stages, there will be some corresponding compression symptoms, such as compression of mediastinal lymph nodes, compression of the superior vena cava, etc., which will cause swelling of the face, head and face discomfort.

If the metastasis to other organs, there will also be some metastatic symptoms, such as headache, abdominal pain or bone pain and other metastatic manifestations.

If the metastasis is to the brain, there will be dizziness, nausea, vomiting, and even dysfunction.

Many peripheral lung cancers do not have any clinical symptoms in the early stage. Only health checkups, only lung cancer screening.

In the past, the traditional chest pain chest X-ray could not detect early lung cancer, and it was found to be locally advanced or advanced lung cancer, so people were afraid of medical checkups, and they found advanced lung cancer in one checkup.

Now we use chest CT instead of chest X-ray, instead of chest X-ray, to find early lung cancer. It can detect sub-centimeter lesions that are smaller than the tip of our thumb, smaller than the tip of our thumb, or even smaller than a peanut, and it can detect sub-centimeter lesions that are smaller than the tip of our thumb.

Especially for the high-risk group of lung cancer, we should pay attention to the health checkups, physical examination after the film to leave a negative plate, there was a nodule before, and the nodule did not change after 5 years. The first time I saw the picture, I had a nodule, and then we found it early.

Generally speaking, after the lung nodule is found by CT, it is thought that there is a possibility of lung cancer, and it is still necessary to confirm the diagnosis by pathology, which is the gold standard, even now, such as PET-CT, including some advanced equipment, may not be able to make a clear diagnosis, and only by finding the pathology can we have a really clear diagnosis.

A kind of discovery is through puncture, CT localization under the puncture, but if the case is very small, such as only 5 mm, 8 mm, the puncture is very difficult, or there are some special parts, such as the distance from the door of the lungs, blood vessels, the trachea is relatively close to the puncture is also more difficult.

Also, because the nodule is in the lung, not in the bronchial lumen, it's very difficult to get to the nodule with bronchoscopy or ultrasound bronchoscopy. There is magnetic navigation, magnetic navigation is through the magnetic force to help take the pathology and.

So it's important to get it clear, especially if the high degree of wai is an early tumor that can be clarified by thoracoscopic surgery.

We need to be vigilant about lung cancer, early detection, early diagnosis, early treatment.

The main symptoms of lung cancer include three points:

One is the symptoms caused by the primary tumor, including coughing, coughing up sputum, hemoptysis, chest pain, chest tightness and so on.

The second is the symptoms caused by intrathoracic extension of the primary tumor, including dysphagia, hoarseness, dyspnea, Horner's syndrome, superior vena cava obstruction syndrome and other manifestations.

Third is the symptoms caused by distant metastasis of lung cancer. It includes metastasis to each organ, causing manifestations similar to that organ. For example, if it metastasizes to the liver, there will be manifestations similar to liver cancer.

Currently, the main treatment for lung cancer is comprehensive treatment mainly based on surgery, which now includes surgery, radiotherapy, chemotherapy, targeted therapy, bio-immunotherapy, and now traditional Chinese medicine. #Chronic Disease Those Things## CK Health Program## Health Science Ranking Competition#
