Lung cancer awareness.
What is lung cancer? The World Health Organization (WHO) defines lung cancer, known as primary bronchial or primary bronchial lung cancer, as malignant tumours originating from respiratory epipelagic cells (bronchial, nucleus and pulmonary bubbles), which can be classified as small cell cancer and non-small cell cancer, depending on the changes in tissue. Lung cancer, one of the most common malignant neoplasms in the world, is the number one cause of death from malignant neoplasms in the country, and the incidence is still increasing, with more men than women, with a ratio of 2.1 to 1. (a) The high risk of lung cancer; Air pollution: includes both outdoor air pollution, such as benzene in the atmosphere, PM2.5 particles, etc., and indoor air pollution from toxic gases from interior fit-out, as well as from indoor environments such as oil and smoke from kitchens during cooking. Occupational factors: Asbestos is recognized as a carcinogen, with significant increases in lung cancer, pleural and mesothelioma in exposed persons, with potential for 20 years or more. In addition, there are arsenic, chromium, nickel, beryllium, kerosene, mustard gas, trichloride, chlorine, tobacco heating products and radon and radon gas from the decay of radioactive substances such as uranium, radon, ionizing and microwave radiation. Dietary habits: Studies have shown that there is less consumption of vegetables and fruit containing beta carrots, and that the risk of lung cancer increases. Genetics and genetic changes: These factors can induce the malign transformation of cells and irreversible genetic changes, including the activation of the original cancer gene and the failure of the cancer gene, leading to uncontrolled cell growth and cancer. Specific mechanisms are not yet clear and are still under further study. With regard to lung cancer, what are the symptoms that require our attention? Symptom 1: Long-term cough; Cancer swelling irritates bronchial mucous membranes, causes symmetrical irritating dry coughs, non-sip or a small amount of white foam mucous sluice. For people with chronic bronchitis and long-term smoking, if the cough level increases, cough lasts longer than three weeks, and the sound of metallic sound coughs, it is necessary to have timely medical attention and screening for lung cancer. Symptom II: chest pain, if sustained acute and severe chest pain, may have tumours in the chest. In the case of continuous pain in the chest or shoulder, the tumour excursion. Symptom III: Repeated fever Thermal heat from lung cancer is mainly of two kinds, one caused by bronchial blockage or catheteric pressure, the other by so-called “cancer heat” and the other by the carcinogenic fever of toxins resulting from tumour cell necrosis, which often occurs after extensive late transfer. Symptom IV: Blood in the tumours or in the carcasses is due to the abundance of blood in the tumour tissue and the fragile vascular state, with a high degree of cough leading to vascular rupture. In the form of an inter-interrupted or persistent blood, the amount may be small, coloured or sharp, or dark, and when cancer and oedema attack the blood vessels, they can cause a haemorrhage. Symptom 5: Unidentified weight loss. Unidentified weight loss, possibly a sign of cancer. Cancer patients suffer from tumour maladies, which consumes their nutrients in large quantities, leading to extreme wasting, anaemia, inactivity, and even complete bedlessness, accompanied by the failure of various organs. Four, how to correct the pulmonary knots, and find the pulmonary knots, to be important, not to be too nervous, let alone general, to avoid a one-size-fits-all error. The shadows of small pulmonary knots, cylindrical and image expression increase in density can be single or multiple. Isolated pulmonary hysterectomy with no typical symptoms is often a soft tissue of a single, clear border, increased density, 3 cm in diameter and surrounded by a gaseous lung tissue. The local pathology > 3 cm is called pulmonary osmosis, with a relatively high risk of lung cancer. The pulmonary knots do not amount to early lung cancer, and many diseases within the lungs form knots, such as inflammation, tuberculosis, fungus, sub-sectional pulmonary failure and haemorrhage. As a result, there is a wide variety of possible diagnoses in the pulmonary hysteresis, including inflammation, faulty tumours, nodule balls, fungi infections, and rigid pulmonary celloma. Malignant may be primary lung cancer or intra-pulmonary transfer cancer. While 80 to 90 per cent of the pulmonary nodes detected during the first CT examination were benign, high priority was given to the fact that there was still a percentage of early lung cancer and regular screening was essential.
