The bad news is when the symptoms show and worsen, its mean that lung cancer already in advance stage. When lung cancer is in early stage, it’s not shows any symptoms or only shows small symptoms that most people will think it’s just small illness or even ignore it.

What are lung cancer symptoms?

Symptoms that may leads to lung cancer are:

1. Coughing is the most common of lung cancer symptoms that experienced by 75% of patients.

6. Difficulty swallowing
7. Coughing up blood

In many patients, the cancer has already spread beyond the original site by the time they have symptoms and seek medical attention. Common sites of metastasis include the brain, bone, adrenal glands, contralateral (opposite) lung, liver, pericardium, and kidneys. About 10% of people with lung cancer do not have symptoms at diagnosis; these cancers are incidentally found on routine chest radiograph.
