Lung Cancer Symptoms and Signs

Raspy and hoarse voice. If you observe hoarseness in voice for a long time, you should pay attention to such sign. Of course, this may be either a simple cold or some easy infection, but also a hoarse voice can be a signal to the occurrence of lung cancer. Continuous hoarseness in the voice can lead to inflammation and irritation of the vocal cords, and obstruct the process of swallowing food.
