Yesterday morning, a heart-wrenching news came...
Former Chinese women's soccer international, Zhang Ouying, runner-up winner of the 1999 Women's World Cup, died in San Diego, USA, at the age of 43.
It is understood that more than half a year ago, Zhang Ouying was diagnosed with lung cancer, although after active treatment, but unfortunately, the women's football veteran still failed to overcome the disease...
Sonorous Rose No. 7 striker Zhang Ouying just took the ball away... Lung cancer, the cancer with the highest incidence in the world in China, is actually not far away from us!
Lung cancer, why is it advanced once it is found?
Lung cancer, which usually includes primary lung cancer and metastatic lung cancer. Simply put, primary lung cancer refers to cancer that grows out of the lungs, while metastatic lung cancer refers to cancer that has metastasized from other parts of the lungs. What we usually call lung cancer refers to primary lung cancer.
Like other cancers, lung cancer is detected earlier and treated, and the higher the survival rate. The data shows that after standardized treatment, the possibility of cure for patients with lung cancer in situ is nearly 100%, while the 5-year survival rate of patients with advanced lung cancer is only about 15%. However, the cruel thing is that most patients are already in advanced stages when they find lung cancer.
Lung cancer is difficult to detect at an early stage because patients often do not feel symptoms in the early stages, and once symptoms appear, they may have progressed to an advanced stage...
Year after year, why didn't lung cancer be found?
You must have doubts, the unit will organize a physical examination every year, one of which is to take a chest X-ray, why can't you find the clues of lung cancer?
This is because the chest x-ray examination during the physical examination has a high rate of missed diagnosis for early lung cancer. On orthostatic chest x-ray, about 43% of the lung area overlaps with tissues such as the heart, mediastinum, and diaphragm, and some early lung cancers are difficult to detect. Even if a mass is found on chest x-ray, its precise location, nature, and staging cannot be determined.
In fact, for people at high risk of lung cancer, low-dose spiral CT lung cancer screening can achieve significant survival benefits, and it is also the only internationally recognized and effective lung cancer screening method.
Because the spiral CT resolution is very high, nodules smaller than 4 mm can also be found, and the radiation of a low-dose spiral CT scan is similar to the radiation of 20 hours of flight by plane, which will not have a significant impact on human health.
Therefore, it is recommended to do a spiral CT examination once a year for people over 40 years old, who smoke for many years, and have a high risk of lung cancer with a family history of tumors. If abnormalities are found, the diagnosis can be confirmed by tissue biopsy further.
What are the signs of lung cancer?
Although the incidence of lung cancer is hidden, there are still some signs to follow, and once these appear, beware!
1. Cough
If the tumor grows on bronchopulmonary tissue, it may cause a irritating cough. Cough is usually the first symptom and initial signal, if it is stubborn, irritating dry cough without sputum, after 1-2 weeks of anti-inflammatory treatment symptoms still do not improve, should be given great attention.
Old smokers with long-term chronic cough should also be wary of lung cancer if their coughing habits change.
2. Fever
After the tumor blocks the bronchi, there are often obstructive lobes of the lungs, and the degree varies, ranging from low-grade fever to severe. Those who have fever accompanied by shadowy lungs should actively look for the cause of the disease and do not easily diagnose it as a cold or bronchitis and delay the condition.
3. Chest pain
Chest pain begins with intermittent chest tightness, pressure or dull pain, and sometimes it is impossible to describe the nature and specific location of the pain. If swelling and pain persist, cancer may involve the pleura.
4. Bloody sputum
There may be a small amount of bleeding when the tumor causes capillary rupture, often mixed with sputum. Many lung cancer patients are found to have bloody sputum. Bloody sputum is characterized by blood streaks or blood clots in the sputum, and rarely with large amounts of hemoptysis. For men and women over 40 years of age, who have no history of hemoptysis and suddenly appear unexplained blood sputum, they should be highly vigilant.
5. Hoarseness
There is a recurrent laryngeal nerve in the mediastinum next to the heart that controls the vocal cords, and after lung cancer metastasizes to the lymph nodes around the recurrent laryngeal nerve, symptoms of hoarseness occur when the nerves are compressed or violated.
6. Low back pain, pain in the spine
When bone metastasis occurs in lung cancer, low back pain or chest and back pain occurs and there are fixed tender points.
7. Unexplained weight loss
Some serious diseases, such as malignant tumors, can cause weight loss. Therefore, a short period of significant weight loss without deliberate weight loss should be vigilant.
The main cause of lung cancer
1. Advanced age: after the age of 55, the incidence of lung cancer increases significantly;
2. Smoking: when the smoking index ≥ 400 years (smoking index = number of years of smoking× the number of cigarettes smoked per day), the incidence of lung cancer increases significantly, and second-hand smoke will also increase the risk of lung cancer;
3. Occupation: long-term contact with inorganic arsenic, asbestos, chromium, nickel, coal tar, dichloromethyl ether and chloromethyl methyl ether, etc. or workers engaged in cooking;
4, air pollution: more and more serious air pollution is also a killer of human health;
5. People with high-risk factors such as history of pulmonary fibrosis or malignant tumors, and family history of lung cancer.
What should I do after I have diagnosed lung cancer?
The most important thing, of course, is to rush to the hospital to seek the help of professional doctors.
At present, the treatment methods of lung cancer are mainly divided into: surgical treatment, radiation therapy (radiotherapy), chemotherapy (chemotherapy), targeted therapy, and biological immunotherapy. The earlier the diagnosis, the earlier the treatment, the higher the five-year survival rate.
People who have not received lung cancer can not be taken lightly, as a member of the lung cancer power, we must do:
1, reduce smoking, even ban smoking and do not smoke second-hand smoke, it is known that about 80% of lung cancer is caused by smoking, control of smoking, can make the incidence of lung cancer greatly reduced;
2. Reduce the inhalation of polluted air, remember to wear professional protective masks in smog weather;
3. Do a good job in the prevention of occupational factors, reduce the amount of radiation and the inhalation of polluting substances by staff;
4. Healthy and scientific diet, eat more fruits and vegetables, and eat less pickled, moldy and burnt foods to prevent lung cancer.
The body is the capital of the revolution,
In addition to heartache, I hope to attract everyone's attention...
