Early diagnosis of lung cancer and prophylactics
Early diagnosis and prognosis of lung cancer The following is a general article on early diagnosis and preparation of lung cancer. Early diagnosis of lung cancer relies mainly on medical imaging and pathological examinations. Since lung cancer is often not visible at an early stage, regular medical examinations and cancer screening are key to detecting early lung cancer. Medical video screening: chest X-ray: Although chest X-ray is a common method of screening for lung cancer, the detection of early lung cancer is limited because of its low resolution. CT scan: CT scans (especially low-dose spiral CT) have a higher resolution and can detect smaller pulmonary knots and anomalies, which are currently the preferred method for lung cancer screening. For high-risk groups (e.g., long-term smokers, people with a family history of lung cancer, etc.) low-dose spiral CT screening is recommended on a regular basis. Pathological examination: Fibre bronchial examination: lung pathologies can be directly observed through fibre bronchoscopy, and a sample for pathological analysis is an important means of identifying lung cancer. Pulmonary biopsy: In the case of pulmonary knots or swellings, tissue samples can be obtained from a perforation or surgical biopsy for a specific diagnosis. Other examinations: Blood tumour marker detection: Although blood tumour marker detection cannot be used as a means of positive diagnosis of lung cancer, changes in levels can be used as a reference indicator for assistive diagnosis. PET-CT: The PET-CT examination combines metabolic and image information to better assess the nature and extent of lung pathologies and is of great value for the diagnosis and phasing of lung cancer. The prognosis of lung cancer depends on early detection, early diagnosis and early treatment. Early lung cancer is treated in a combination that is mainly surgically removed, with a high survival rate of five years, while the projection for later lung cancer is relatively poor. Early lung cancer prognosis: Early lung cancer patients have not experienced any cancer transfer, with priority surgical treatment, including pulmonary folic removal and local lymphomy. After the operation, some patients may need complementary chemotherapy or treatment to improve their efficacy. Early lung cancer has a high five-year survival rate, and some patients can even reach a clinical cure. It needs to be noted, however, that even early lung cancer is likely to recur or to shift and therefore requires close follow-up and monitoring after treatment. Post-late lung cancer: Patients of late-stage lung cancer have undergone cancer transfer and treatment is more difficult and relatively poor. At this point, the main objectives of treatment are to alleviate symptoms, extend life and improve the quality of life. The treatment of advanced lung cancer includes chemotherapy, treatment, target-oriented treatment, immunization, etc. Specific treatment programmes need to be individualized according to the patient ‘ s specific circumstances and pathology type. Measures to improve the prognosis of lung cancer Regular medical examinations and cancer screening: for high-risk groups, it is recommended that low-dose CT screening be carried out on a regular basis to enable early detection of lung cancer. Improvement of living habits: Good living habits such as cessation of smoking, drinking, maintenance of healthy diet and moderate exercise help reduce the risk of lung cancer. Active treatment: Once lung cancer has been diagnosed, treatment should be actively coordinated with the doctor ‘ s treatment programme to improve efficacy and prognosis. Psychological support: Patients with lung cancer often face greater psychological stress and burden and need family and social support and care. At the same time, patients should remain positive and optimistic and contribute to the fight against disease. In sum, early diagnosis and prognosis of lung cancer are essential to the survival and quality of life of patients. Measures such as regular medical check-ups, cancer screening and active treatment can increase the rate and pre-emption of lung cancer.
