Since the beginning of winter, many areas in the north have been in a state of dry, cold air.
This environment is most suitable for the activities of various pathogens, and is the season with the highest incidence of respiratory diseases, including bronchitis, pneumonia, common cold and so on!
One of the most common symptoms of respiratory illness is a cough.
Many people in the presence of cough, especially when hearing the baby cough, do not ask indiscriminately, turned out the family medicine cough medicine.
But in fact, from the clinical point of view, it is not wise to take medicine as soon as you cough, because cough has two sides!
A cough is both a sign of illness and the body’s mechanism for protecting itself!
Cough is the result of movement and muscle contraction of respiratory mucosa cilia.
Cough can be accumulated in the respiratory tract secretions, foreign bodies out of the body, reduce the further accumulation of harmful substances in the respiratory tract. If at the beginning of the cough, blindly take cough medicine, but will cause sputum accumulation in the respiratory tract, breeding a large number of bacteria, aggravating the development of the disease!
Clinical does not suggest that we rush to treat the cough, but to find the cause of coughing, the original onset of control, cough symptoms will be gradually relieved.
A recent cough that does not respond to medication or rest for a long time is likely to be associated with a serious, pathogenic disease: lung cancer!
- Persistent irritant cough
According to the clinical data, lung cancer appears in different places and causes different functional damage. However, in China’s lung cancer patients, most of the cancer is growing in the lung air, so cough is one of the most common symptoms of lung cancer. Patients with cough as the first symptom accounted for about 35%~75% of all patients.
In the development of lung cancer, it will not only stimulate the atmosphere, but also lead to changes in bronchial mucus secretion, obstructive pneumonia, atelectasis and other problems.
In the early stage of lung cancer, patients often show a cough similar to foreign body stimulation, and the typical manifestation is paroxymoron irritant dry cough. Even if they take cough medicine, the effect is not obvious because the cancer does not disappear.
For patients who have been smoking for years or have chronic bronchitis, they should be on high alert for lung cancer if they suddenly have a cough recently, the degree of cough has increased, the frequency of cough has become more frequent, or the nature of cough has changed!
He coughed and he coughed blood
Cancer can grow quickly, cancer cells can continue to divide, the fundamental reason is because the cancer has a large number of blood vessels distribution, can provide adequate nutrition.
However, the vascular texture of these tumors is relatively fragile, and they are easy to crush and rupture, which can lead to bleeding. In the process of the patient cough, blood vessels may rupture bleeding, patients often have sputum with blood, a small amount of hemoptysis and other symptoms.
In addition, hemoptysis may occur after tumor necrosis, invasion of large vessels, or vasculitis.
Once the patient’s large blood vessel rupture, large cavity formation, or tumor ulceration into the bronchial, pulmonary vessels, patients often will have difficult to control the symptoms of large hemoptysis.
Both types of abnormal coughing can be signs of lung cancer.
People who have been smoking for years, already have chronic respiratory diseases, and have a family history of lung cancer should be vigilant and seek medical screening in time.
In addition, regular lung cancer screening is also necessary for high-risk groups to learn about lung health and catch cancers early.
