These 3 types of people are at high risk of lung cancer! 4 signs of upper body, don't take it lightly!
In recent years, China's cancer statistics report shows that the incidence and death of lung cancer ranks first among all cancer types, and the incidence rate shows a trend of increasing year by year.
A survey of relevant data shows that on average, the number of newly diagnosed lung cancer patients in China has reached more than 800,000 each year, and the number of patients who died of lung cancer has reached more than 700,000!
Not only China, but many countries around the world have reported increased incidence and mortality of lung cancer. It is the "strongest king" among all solid malignant tumors.
Moreover, due to the lack of typical early symptoms of lung cancer, more than 70% of lung cancer patients had already entered the middle and late stage when they first went to the doctor with discomfort, and even missed the opportunity for surgery!
In fact, lung cancer is not without traces. From a clinical point of view, three major groups of people, such as long-term heavy smoking, a history of chronic lung disease or a family history of lung cancer, and a history of occupational exposure, are those at high risk of lung cancer.
If you have the following four symptoms recently, beware of the signs of lung cancer:
- Hoarseness: In most cases, hoarseness is related to common respiratory diseases, loud speaking, long-term smoking, and alcoholism.
However, this type of hoarseness can be relieved with medication and proper rest. The hoarseness caused by lung cancer is because the tumor in the lung and the metastatic and enlarged lymph nodes compress the recurrent laryngeal nerve, so the patient will have hoarseness that is difficult to control and develops extremely rapidly. Drugs are often difficult to control, and the patient may even suffer So completely mute.
At the same time, affected by the paralysis of the left vocal cord, the patient may also have symptoms of upper airway obstruction;
- Cough: Usually, the functional damage caused by canceration in different parts of the lung is different, but cough is the most common first symptom of lung cancer, and nearly 60% of lung cancer patients have the first symptom of cough.
It is mainly manifested as paroxysmal, irritating cough or dry cough. The patient's cough will become more and more frequent as the disease progresses, the quality of the cough will gradually change, and even a high-pitched metallic cough will appear.
The reasons for its appearance are mostly related to factors such as cancer and secretions that stimulate the large bronchus, change the secretion of bronchial mucosa, and induce pneumonia;
- Blood in sputum: This is also one of the typical symptoms of lung cancer, and it often appears together with cough. Because the tumor in the patient's lungs has already formed, when coughing, it will cause a strong impact and pressure on the tumor, which will lead to the rupture of blood vessels on the surface of the tumor, and the symptoms of blood in the sputum will appear.
In addition, repeated hemoptysis and hemoptysis in patients may also be related to factors such as local tumor necrosis and vascular inflammation.
This kind of hemoptysis is mostly manifested as intermittent or continuous repeated bloody sputum and a small amount of hemoptysis in the initial stage.
After the patient's large blood vessels are ruptured, affected by blood overflow, the patient may experience massive hemoptysis that is difficult to control, or even life-threatening due to excessive blood loss;
- Chest pain: Patients with chest pain as the first symptom of lung cancer account for 1/4 of all patients. This chest pain is mostly related to prolonged coughing in the early stage, and manifests as irregular dull pain or dull pain.
As the cancer continues to develop, the cancer cells begin to infiltrate the surrounding area. After infiltrating the pleura, the patient may experience pleural-like pain, which is characterized by intermittent and sharp abnormal pain in the chest, and eventually develops into constant drilling pain.
In addition, when cancer accumulates in surrounding tissues or blood vessels, compresses the peripheral nervous system, and merges with malignant pleural effusion, pain can also occur.
The repeated occurrence of the above four symptoms may be a signal of lung cancer, and it is necessary to seek medical attention in time for targeted lung cancer screening.
In fact, from a clinical point of view, regardless of whether or not people at high risk of lung cancer have symptoms, in order to detect lung cancer as early as possible and prevent cancer from reaching an irreversible stage, regular cancer prevention screening is required. The most effective screening method, It is actually a low-dose spiral CT.
