Some of the early signs and symptoms of lung cancer can include:

1. Persistent cough that worsens over time

2. Blood in the cough or phlegm

3. Chest pain that worsens with deep breathing, laughing, or coughing

4. Shortness of breath or wheezing

5. Fatigue or weakness

6. Unexplained weight loss

7. Hoarseness or voice changes

8. Frequent respiratory infections such as bronchitis or pneumonia

It’s worth noting that these symptoms can also be caused by other conditions, so it’s important to consult with a healthcare professional for a proper evaluation and diagnosis. Additionally, keep in mind that not everyone with lung cancer experiences symptoms in the early stages. Regular check-ups and screening tests can help detect lung cancer before symptoms occur.
