However, as the cancer progresses, common symptoms may include persistent coughing, chest pain, shortness of breath, hoarseness, unexplained weight loss, fatigue, and recurring respiratory infections. It is important to pay attention to these symptoms, especially if they persist for an extended period.
Diagnosis: Diagnosing lung cancer involves a series of tests and examinations. If a doctor suspects lung cancer based on the patient’s symptoms or risk factors, they may order imaging tests such as chest X-rays, CT scans, or MRI scans to visualize the lungs and identify any abnormal growths or masses. Additionally, a biopsy may be performed to obtain a tissue sample for further analysis. This can be done through a bronchoscopy, in which a flexible tube is inserted into the airways to collect a sample, or through a needle biopsy, in which a thin needle is guided into the lung to extract a tissue sample. Once the diagnosis is confirmed, further tests, such as blood tests and staging procedures, are conducted to determine the extent and spread of the cancer.
In conclusion, understanding the causes, symptoms, and diagnosis of lung cancer is essential for both individuals at risk and healthcare professionals. By recognizing the risk factors, being aware of potential symptoms, and seeking medical attention promptly, the chances of early detection and successful treatment can be significantly improved. It is important to remember that prevention is key, and quitting smoking or avoiding exposure to harmful substances can greatly reduce the risk of developing lung cancer.
