9. A hoarse voice
Apparently, none of us know the real sound of our own voices. This is because when we speak, the sound echoes through our sinuses and then reaches our ears. This dissipation and reverberation results in us hearing our own voices at a pitch that is slighter lower than its natural one. While we may not know the true sound of our voices, we will definitely notice if it sounds different all of a sudden. Better yet, other people will notice if your voice has changed. If this is the case and you or those around you have detected a change in your voice, then it is a good idea to take note of it. This could be a sign of lung cancer.
The recurrent laryngeal nerve controls the voice box and is split into two parts. One part of the nerve passes through the chest by the left lung. If a tumor is present in the left lung, it could be applying pressure to this nerve which would cause hoarseness in one’s voice.
While this can be a sign of lung cancer, environmental factors first need to be ruled out. This could be illness, smoking, gastrointestinal reflux disease and even a person’s profession (teachers tend to use their voices a lot).
If a person’s voice has become hoarse, and none of these factors are present, then a physician should be consulted. Further testing would need to be done before cancer is diagnosed, but a change in voice should definitely not be completely ignored. When visiting a doctor, don’t forget to take all medical records and do not fail to mention any family history of cancer.
