Attention! Beware of lung cancer if early symptoms are mild or atypical

I have been feeling shoulder pain and thought it was just frozen shoulder, but repeated treatments did not improve. One year later, I found out that the shoulder pain I was used to was actually the late stage of lung cancer. I regretted it so much... Professor Zhou Caicun, director of the Oncology Department of the Municipal Pulmonary Hospital, explained that the current incidence of lung cancer is about 35/100,000, of which the incidence of superior pulmonary sulcus cancer accounts for about 2% to 5% of lung cancer. Clinically, many patients initially felt shoulder pain, so they went to the orthopedics department for a "round trip" and came back, but it turned out to be the late stage of lung cancer, which had also metastasized to the shoulder, delaying the disease. According to experts, according to foreign countries, the misdiagnosis rate in this regard is relatively high, especially when it is discovered, it is mostly late stage metastasis. The following experts will introduce you to the early symptoms of lung cancer.

The growth trend among women is faster

"In the past, we thought lung cancer was often a cancer of the elderly, cigarettes and men, but now, the trend of lung cancer in modern women is increasing faster than that in men." According to Professor Liao Meiling's analysis, the accelerated growth trend of lung cancer in women may be closely related to the increase in the number of modern female smokers, the younger age of smoking, passive smoking in women, and women's greater exposure to kitchen fumes. According to Professor Zhou Caicun's analysis, currently about 87% of lung cancer is related to smoking, which also includes the risk of passive smoking.

Lung cancer is the most common malignant tumor in my country. According to statistics, about 600,000 people die of lung cancer in my country every year. In particular, the number of lung cancer cases has increased nearly fivefold in the past 30 years. Since the early symptoms of lung cancer are highly hidden, about 70% of non-small cell lung cancer patients are often diagnosed in the local advanced stage or metastasis.

Lung cancer is actually preventable and controllable

In fact, lung cancer is preventable and controllable. Lifestyle accounts for 84% of the impact on tumors. Lung cancer can be prevented by not smoking, drinking less, improving living environment, adjusting diet structure, and strengthening health examinations. In addition, quitting smoking is the most important. In addition to inducing lung cancer, smoking also reduces the effectiveness of surgery, chemotherapy and targeted therapy.

If lung cancer can be detected early, its cure rate is not low. At present, the 5-year survival rate of stage I lung cancer can reach about 60% to 80%, and the 5-year survival rate of stage II lung cancer can reach 40% to 50%. Experts remind lung cancer patients that the key is early detection and early treatment, which is very important. Just like "cars need maintenance", people also need maintenance. For men with a family history of tumors, long-term smoking and over 50 years old, often have chest pain, hoarseness, coughing up blood and other symptoms, or shoulder pain in the lungs, numbness of fingers, etc., they need to be screened as soon as possible to rule out the possibility of lung cancer.

Regular symptom checks

However, experts also remind the public not to panic blindly. Experts emphasize that typical symptoms of lung cancer are dry cough without sputum, chronic cough, coughing up blood, shortness of breath, chest pain, bronchitis, repeated pneumonia, and unexplained weight loss and loss of appetite. High-risk groups with a family history should be followed up regularly and checked every year or every six months. For patients with frozen shoulder who have not been cured for a long time, experts remind that as long as a chest X-ray is taken early to confirm the diagnosis, misdiagnosis can be avoided.

In addition, lung cancer patients also have physical symptoms such as male breast enlargement, phlebitis, endocrine dysfunction, etc. The most common of these are clubbing and hypertrophic osteoarthritis. Therefore, if these physical symptoms occur, a chest X-ray should be performed to rule out the possibility of lung cancer.

People who are at high risk of lung cancer now include long-term smokers over 45 years old, people who have long-term exposure to radioactive substances, and those with a family history of cancer. People who have long-term exposure to high-oil fume environments in the kitchen are also listed as key populations for census and need to have a physical examination every six months to one year.

Early screening is crucial

The main screening methods for early lung cancer are chest X-ray and sputum cytology. Chest X-ray is convenient and economical, and the patient does not feel pain, but the disadvantage is that it cannot detect tumors smaller than 1 cm. Sputum exfoliative cytology is one of the important methods for diagnosing lung cancer, which is simple and easy. It examines the first sputum discharged after a deep cough in the morning. Sputum with blood is better, and it needs to be sent for examination for 6 to 8 consecutive days to find exfoliated cancer cells. However, sputum examination also has defects, and the false negative rate is relatively high, especially for patients with peripheral lung cancer. Because the tumor is located in the periphery of both lungs, far away from the large bronchi, it is difficult to bring out cancer cells from the sputum.

For patients with typical symptoms and high suspicion of lung cancer, whose chest X-ray and sputum examination results are negative, bronchoscopy can be performed directly to obtain tissue for pathological examination.

Some hospitals are currently carrying out percutaneous lung puncture under CT guidance, and have performed more than 1,000 cases, making the diagnosis positive rate of peripheral lung cancer more than 80%-90%. The use of membrane liquid-based thin-layer cytology detection technology, namely the new Precision TCT detection system, has significantly improved the positive rate of sputum detection, and the diagnosis and treatment of difficult and complicated lung diseases has reached the domestic advanced level.

The clinical symptoms of the two types of lung cancer are different

More than 96% of lung cancer originates from the bronchi of the lungs. According to the different sites of onset on the bronchi, it can be divided into two types: central type and peripheral type. The clinical symptoms of the two types of lung cancer are different, and the diagnosis methods are also different.

Central lung cancer: Originates in the central part of the lung. Its symptoms include: irritating cough, blood in sputum. (It can be in the form of blood streaks, blood spots, or mixed with sputum). As the tumor gradually grows, fever, chest tightness, shortness of breath, etc. may occur. Because this type of lung cancer is located in the central part of the lung, its shadow is often covered by the shadow of the heart and large blood vessels, so it is easy to misdiagnose by chest X-ray examination alone. The best examination methods include sputum cytology examination; tracheal and bronchial tomography, CT examination, bronchography, mediastinal inflation angiography, and fiberoptic bronchoscopy, which are the most valuable examination methods.

Peripheral lung cancer: It originates from the periphery of the lungs, so it rarely causes symptoms such as coughing and hemoptysis. A few patients may have dull pain, dull pain, or intermittent pain in the chest, but when the tumor grows and invades the pleura and chest wall, it may cause localized continuous severe pain or stabbing pain in the chest. Many patients may be misdiagnosed as tuberculosis or lung inflammation for a long time, which delays treatment. In order to avoid misdiagnosis, anyone over 40 years old who suddenly finds a round shadow in the lungs and cannot be diagnosed with tuberculosis should take surgical treatment or dynamic observation for 1 to 2 months in the early stage. If the round shadow gradually increases or there is no obvious change after drug treatment, it should never be delayed, but should be quickly checked by a thoracic surgeon to strive for early surgery.

Through the traditional Chinese medicine syndrome differentiation and treatment to develop personalized plans, starting from the overall situation, combining anti-cancer and strengthening the body, multiple controls to block the continued invasion of carcinogens, clear carcinogens in the patient's body, comprehensively restore the patient's immune function, improve the living environment of cancer cells, promote cancer cell apoptosis, thereby improving symptoms and controlling the disease, inhibiting tumor development, and gradually shrinking the tumor until it disappears completely.

The above is the lung cancer caused by minor illnesses introduced by experts. Expert Tips: If your health has symptoms of illness, you can choose the appropriate treatment according to your symptoms, but do not delay diagnosis, and do not let your life be ruined in hesitation. You should go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
