Quick Answer
The early signs of lung cancer may include a persistent cough, coughing up blood, chest pain, shortness of breath, unexplained weight loss, hoarseness, and frequent chest infections. These symptoms can also be caused by other lung conditions, but if they persist for more than a few weeks, it is important to consult a pulmonologist for evaluation.

A cough that lasts for more than 3 weeks or keeps getting worse should not be ignored.
Coughing Up Blood
Even a small amount of blood in your sputum requires immediate medical attention.
Shortness of Breath
Difficulty breathing during routine activities may be an early warning sign.
Chest Pain
Persistent chest pain that worsens while coughing or taking deep breaths should be evaluated.
Unexplained Weight Loss
Losing weight without changes in diet or exercise may indicate an underlying health problem.
Hoarseness
A voice that remains hoarse for several weeks could be a symptom of lung cancer.
