Stage 1 lung cancer is the earliest stage of the disease, where the tumor is typically confined to the lung and has not spread to nearby lymph nodes or other parts of the body. During this stage, symptoms may be subtle or not noticeable, which makes early detection challenging. Understanding the Stage 1 lung cancer symptoms is critical for catching the disease early when treatment options are most effective. Common symptoms of stage 1 lung cancer may include a persistent cough, coughing up blood (hemoptysis), shortness of breath, chest pain, and unexplained weight loss. However, many of these symptoms are similar to those seen in other respiratory conditions, such as chronic bronchitis or a respiratory infection, which is why they are not always immediately linked to cancer. Dr. Harshvardhan Puri, a leading pulmonologist in Delhi and Gurgaon, offers comprehensive diagnostic and treatment options to help detect and manage lung cancer at its earliest stages.
