Five typical signs of early lung cancer in women.
In the past, we thought that lung cancer was often elderly cancer, cigarette cancer and male cancer, but nowadays, the increase in lung cancer among modern women is faster than that of men. So how do women find lung cancer early? Let us first analyze a set of common symptoms of lung cancer.
Cough and sputum are the main criteria for early symptoms of lung cancer
This table counts five typical early symptoms of lung cancer, as well as the number and proportion of people suffering from these signs. The sample is some countries’s lung cancer patients in 2013, and the sample size is 90,300,220.
From the above statistical table, we can clearly see that the early symptoms of lung cancer are mainly low-grade fever, cough, hemoptysis, sputum, and chest pain. Among the five symptoms, 93% of patients have cough symptoms, the number is about 83,979,205, and the second most important symptom is sputum, which accounts for 88%, about 79,464,195.
These two are the most important The symptom of is the most important criterion to measure the early symptoms of cancer patients.
About two-thirds of female patients have cough symptoms. It can be manifested as a mild dry cough or a severe cough, a higher frequency of coughing, or a night cough. However, in patients with chronic long-term cough, once the nature of the cough changes, or frequency changes or night cough occurs. We must be alert to lung cancer.
Sudden dry cough and choking cough for more than two weeks, and anti-inflammatory treatment is ineffective, or the original chronic cough suddenly changes in nature, and continuous, uncontrollable cough is one of the most painful symptoms of lung cancer.
Among the five most typical symptoms, hemoptysis accounts for the smallest proportion, which is only 52%, and the number is 46,956,114. However, it should be noted that hemoptysis is one of the early symptoms of female lung cancer. It is more obvious in female smokers.
It is mostly manifested as blood in sputum or intermittent bloody sputum. There are also patients with repeated inflammatory changes in a certain part of the lungs. . In addition, chest tightness and shortness of breath are also common early symptoms of female lung cancer.
Except for tumor obstruction of the bronchi, which causes atelectasis or lung inflammation, which causes chest tightness and shortness of breath, the symptoms of lung cancer are more obvious in the late stage, and lung cancer is more severe when pleural effusion occurs.
Early screening is essential
The current high-risk population of lung cancer includes long-term smokers over 45 years old, long-term exposure to radioactive substances, and those with a family history of tumors.
People who have been exposed to the kitchen with high oily smoke environment for a long time are also listed as the key population for the census, requiring a physical examination every six months to a year.
Experts say that 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 is painless, but the disadvantage is that it cannot find a mass smaller than 1cm.
Sputum exfoliation cytology is one of the important methods for the diagnosis of lung cancer. It is the first mouthful of sputum discharged from a deep cough after waking up in the morning.
Bloody sputum is better, and it needs to be submitted for 6-8 days. Shedding cancer cells. However, the sputum examination also has drawbacks.
The false negative rate is relatively high, especially for patients with peripheral lung cancer. Because the cancer is located on the periphery of both lungs, far away from the large bronchus, it is difficult to bring out cancer cells from the sputum.
