According to a research, almost 40% of patients suffering from cancer were diagnosed when the cancer has evolved in the late 3rd stage, meaning it has already made big progress.
This is as it is because lung cancer shows no symptoms and it is hard to notice it in its early stages. Fortunately, there are 7 signs that indicate lung cancer and can help you in diagnosing it before it is too late.
1. Persistent Cough
Pay attention to the way you cough. If the cough is gone after one or two weeks, it means you have caught a regular cough due to a respiratory infection or a cold. However, if you suffer from the same cough even after two weeks it might indicate to lung cancer.
