Lung cancer is known as the largest cancer in mainland China
As a malignant tumor that occurs in the lungs, lung cancer originates in the bronchial mucosa of the lungs, and its morbidity and mortality rate are very high.
In recent years, the number of new lung cancer patients on the mainland has gradually increased every year, and if the mainland has not controlled smoking and air pollution in time, it is expected that by 2050, 1 million people will die of lung cancer every year on the mainland.
There are many symptoms in the early stage of lung cancer, but these symptoms are easily ignored by patients.
Once there is no timely treatment in the early stage, the cancer cells will metastasize to distant distances, which will lead to multiple organ failure of patients in a short period of time, which is more harmful to the patient's life.
What are the symptoms of early lung cancer?
1. Chronic and repeated cough
Most patients experience a series of symptoms of lung discomfort, the most important manifestation is cough, and about 70% of patients have the first symptom is cough.
When a tumor appears in the lungs, it will change the secretion of bronchial mucus and can cause the pleura to be violated, resulting in repeated chronic coughing. Most patients do not cough up sputum when coughing, usually irritating dry cough.
If the patient still smokes or suffers from the harm of second-hand smoke at this time, the cough will worsen, and there will be high-pitched, metallic tones.
Second, chest tightness, breathing difficulties
About 10% of patients, the first symptom is chest tightness, especially in patients with central lung cancer, as well as patients with poor lung function, this symptom will be very obvious.
In the presence of chest tightness symptoms, patients are also accompanied by symptoms of poor breathing and shortness of breath and shortness of breath. Symptoms are especially pronounced when the mood is agitated, lying flat, and performing activities.
3. Pleural irritation symptoms
Patients in the early stages of lung cancer develop a series of symptoms of pleural irritation, specifically manifested as chest pain.
About 25% of patients have chest pain as the first symptom, especially in peripheral lung cancer. As the tumor grows, it irritates the pleura and chest wall, causing the patient to have persistent and sharp pleural pain.
This chest pain does not improve with some medications, is intermittent and repetitive, and radiates to the patient's back and shoulders.
4. Abnormal bleeding
About 30% of lung cancer patients, the first symptom is pulmonary hemorrhage.
When the patient coughs, he spits out a small amount of sputum with blood streaks. Lung tumor texture is relatively brittle, when the patient coughs, it will cause the tumor surface blood vessels to rupture and bleed.
When patients cough, they occasionally have some blood in the sputum. If the tumor blood vessel rupture is severe, it will cause the patient to appear hemoptysis.
5. Manifestations of constitutional symptoms
Once cancer cells appear in the lungs, patients develop a range of systemic symptoms, such as fever.
About 30% of patients have the first symptoms of repeated fever, the body temperature is generally 38 degrees, and the use of antibiotics can play a role in reducing fever.
In addition, some patients will have cancerous fever, at this time the use of ordinary antipyretic drugs has no effect, the use of indole drugs to have anti-fever effect.
Other patients will experience constant emaciation, as well as rapid loss of appetite, anemia, and enlarged clavicle lymph nodes.
Smoking is still the biggest factor in lung cancer
Who reports that 85%-90% of all patients who die from lung cancer are attributable to smoking, and nearly 6 million people die each year worldwide from smoking as well as second-hand smoke.
In addition, people who live with smokers for a long time will also have a 25% higher chance of developing lung cancer, and being forced to inhale second-hand smoke for a long time will also significantly increase the chance of cancer.
The study also found that lung cancer caused by smoking is not sensitive to chemotherapy drugs and targeted drugs, which affects the treatment effect.
All in all, smoke is harmful and not beneficial, so quit it as soon as possible!
