Lung Cancer

Application Details :

One kind of cancer that begins in the lungs is lung cancer. It is the primary cause of cancer-related mortality globally, accounting for more fatalities than the combined effects of colon, prostate, and breast malignancies. This illness is brought on by the uncontrollable growth and mutation of lung cells, which can lead to tumors that impair lung function and may even spread to other body regions. Small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) are the two primary forms of lung cancer. NSCLC makes up for 85% of all cases, making it the most prevalent kind. There are multiple subtypes of it, including big cell carcinoma, squamous cell carcinoma, and adenocarcinoma. Although SCLC is less prevalent than NSCLC, it tends to grow and spread more quickly.Lung cancer is primarily caused by smoking. More than 7,000 compounds, many of which are carcinogenic (cause cancer), are found in cigarette smoke. Lung cancer risk can rise even in the presence of secondhand smoke. Smoking, however, is not a factor in every instance of lung cancer. A family history of lung cancer, pollution, asbestos exposure, and radon gas exposure are other risk factors. Lung cancer symptoms can not show up in the early stages or they might be misdiagnosed as other respiratory disorders. A chronic cough that becomes worse with time, blood in the cough, hoarseness, chest pain that gets worse when you cough or breathe deeply, and recurrent respiratory infections like pneumonia or bronchitis are common symptoms.To identify the kind and stage of cancer, a variety of imaging procedures, including CT and X-rays, biopsies, and other tests, are typically used in the diagnosis process. Depending on the kind and stage of the disease, there are a variety of treatment options available, such as immunotherapy, targeted therapy, chemotherapy, radiation therapy, and surgery. For individuals who are at high risk, such as those who smoke often or have smoked in the past, screenings like low-dose CT scans are advised since early detection is essential for improved treatment outcomes.The mainstays of lung cancer prevention include abstaining from tobacco use, including secondhand smoke, and minimizing exposure to other recognized carcinogens such as asbestos and radon. Research is constantly improving treatment options and results for patients with lung cancer, giving them hope for higher survival rates and improved quality of life.
