What are common symptoms of lung cancer?

Cough and hemoptysis are indeed common symptoms associated with lung cancer. The presence of a persistent cough can often be one of the earliest signs that something is wrong in the lungs. This cough may change in character, becoming more severe or chronic over time. Hemoptysis, or coughing up blood, is particularly concerning and can occur as a result of tumor growth leading to the erosion of blood vessels or tissues within the lung.

Recognizing these symptoms is crucial in the early detection and diagnosis of lung cancer, as they can prompt further investigation through imaging studies and biopsies. Other common symptoms that may accompany these include weight loss, fatigue, and changes in appetite, which can further support the diagnosis of lung cancer.

In contrast, while cough and fever can occur with various respiratory conditions, they are not specific indicators of lung cancer. Chest pain and wheezing may also be observed in other pulmonary conditions, and shortness of breath may arise from multiple causes including lung infections or other respiratory diseases, but paralysis is not a symptom associated with lung cancer.
