How to understand lung cancer correctly
What is lung cancer?
Lung cancer is one of the most malignant tumours in the world with the highest morbidity and mortality rates, accounting for 15-20 per cent of all malignant tumours.
Our lung cancer patients account for about 60 ~70 per cent of global lung cancer cases. The incidence and mortality of lung cancer is known to be among the highest in the world. Although early lung cancer symptoms are similar to cancers, failure to detect and treat in a timely manner results in a significant reduction in the survival rate of late-stage patients over five years, with an overall survival rate of less than 10 per cent over five years.
As a result, there is a greater awareness of “cancer”, which is not equivalent to malignant tumours; cancer is not clearly defined.
2. Why is lung cancer more likely to happen to persons over 40 years of age?
Lung cancer is closely related to genetic, tobacco and environmental pollution. Studies have found that environmental pollution leads to an increase in the incidence of lung cancer among males, especially among people who are chronically exposed to carcinogenic substances such as asbestos, coal, oil, asphalt and rubber. Smoking also increases the risk of lung cancer among men. Therefore, it is recommended that men over 45 years of age should do a low-dose spiral CT examination every year.
3. What are the types of lung cancer?
Lung cancer can be classified into gland and gland cancers, the three types of lung cancer most commonly clinically, depending on where the tumor occurs. Among these is the most common type of cancer, which accounts for more than 80 per cent of lung cancer patients and is less advanced.
How do you diagnose lung cancer?
There are a number of methods for the diagnosis of lung cancer, such as video screening, the organization of pathology examinations, molecular targeting drug treatment, genetic testing, etc. Different patients will have different diagnostic methods, and if the doctor makes a diagnosis based on the patient ‘ s symptoms and signs, he/she can choose the appropriate method of treatment. Visual examinations: Currently, there are mainly CT and MRI tests in clinical terms, and CT is one of the routine examinations for lung cancer. MRI is the most accurate and effective diagnostic tool for CT imaging, which detects early and distant transfer of stoves, and therefore recommends that lung cancers from 40 years of age and above be performed every six months to every year. Molecular target-to-pharmaceutical treatment: The presence of specific substances in tumour tissues is decisive for the efficacy of the target-to-pharmaceuticals, and currently includes mainly target-to-treatment drugs and non-target-to-pharmacological drugs.
5. What are the early symptoms? In general, early symptoms of lung cancer are: cough, blood in the crotch; chrome, mainly haemorrhage with severe cough; chest pain, the unknown nature of the pain or blunt pain, most of which is persistent insinuations or blunt pain.
6. How should patients be detected early? Currently, the most common method of early lung cancer diagnosis is “low-dose CT (LDCT)” which is characterized by safety, simplicity and economy and is widely available among the general population. For patients with non-symptomatic lung cancer, the pulmonary stoves can be detected through low-dose CT tests; for patients with symptoms, care is taken to follow up and review regularly. Low-dose spiral CT detection method: 1 regular X-ray machine + low-dose scanner + chest tablet; 2 high-precision digital aerovascular imaging (DSA); 3 PET/CT, an innovated, accurate, dynamic and continuous chest X-ray screening method. It is characterized by accuracy, safety, speed and absence of environmental contamination (one hour, one hour, one hour). The methodology has been widely applied in early detection and treatment of lung cancer in developed countries such as Europe and the United States.
7. How can long-term smoking be avoided to cause bodily harm? Tobacco smokers should avoid exposure to second-hand and third-hand smoke, and stay away from more polluting environments, such as car exhaust, plant exhaust and contaminated rivers and lakes. If there was a real need for smoking, it would be better to stop smoking and try a new life. The reduction of passive smokers is two to three times more likely than active smokers to have lung cancer. Get a good life habit, stay away from second-hand smoke. Less salt: Sodium ion in salt enters directly into the blood, increases the burden on the kidneys, also destroys the cytological membranes and makes the body more absorbible to harmful substances. No sugary drinks (e.g. milk tea) or high sugary foods and fruits (e.g. bananas, apples).
Is there a family history that requires examination?
Some lung cancer patients are concentrated in the family, some of them have had lung cancer in their immediate family, and their children are at higher risk, so that other members of the family should be screened regularly for lung cancer. It is generally recommended that persons over 40 be examined once a year and those under 40 be examined once a year.
You know what?
Tumour cells enter the blood cycle in a number of ways, some of which can flow back through lymphoma to the lungs, resulting in a higher rate of relapse after surgery for lung cancer patients.
Do you need to take a lot of drugs during treatment?
Drug treatment is one of the important tools for tumour treatment, but not all patients need it. Some patients have chronic diseases such as hypertension, hypertension and diabetes, which also require long-term medication. For patients with these diseases, medications should be selected under the direction of a doctor.
What are the advantages and side effects of post-operative treatment or chemotherapy, and how can it be ensured that the process is carried out? After the lung cancer, doctors generally recommend treatment. Treatment reduces the patient ‘ s post-operative suffering and increases the success rate. Treatment can significantly improve the efficacy of chemotherapy and reduce the adverse effects of chemotherapy, such as nausea, vomiting and diarrhoea. In addition, therapeutic treatment can act as a disincentive to the growth of cancer cells and improve the effectiveness of cancer treatment. However, after treatment, routine chemotherapy is still required to control the progress of cancer and to avoid its recurrence or transfer. 12. How can the treatment of lung cancer differ from other cancers and what should be done to achieve the best results? Many patients are confused when treating lung cancer and do not know what to do to achieve the best. There are many ways to treat lung cancer, but we cannot simply say which is better. Clinical research on lung cancer is already well advanced and a more sophisticated methodology has been developed.
13. Whether lung cancer is incurable, whether it can be treated effectively, how to prevent and control lung cancer, and how to avoid cancer. Lung cancer is curable and is currently treated internationally in the form of surgery, treatment, chemotherapy, target treatment and immunization. We can try to avoid cancer through active scientific prevention and control. Lung cancer is also not completely impossible to prevent and control, and can reduce the risk of cancer through our usual good living habits, a reasonable diet and exercise.
