What are the symptoms of lung cancer?

Lung cancer often has no symptoms in the early stages. Symptoms tend to develop as the cancer grows and presses on nearby structures, such as airways, blood vessels, or the lymphatic system. Symptoms can vary depending on the location and size of the tumor.

Some common symptoms of lung cancer include:

- A persistent cough that does not go away.

- Hoarseness or changes in the voice.

- Shortness of breath or wheezing.

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

- Coughing up blood or rust-colored sputum.

- Fatigue or weight loss without a known cause.

- Weakness or numbness in one arm or hand.

- Swollen lymph nodes in the neck or above the collarbone.

- Headache or dizziness.

- Difficulty swallowing.

- Bone pain.

- Loss of appetite.

It is important to note that these symptoms can be caused by other conditions as well, so it is important to see a doctor if you experience any of these symptoms to determine the cause.
