Sign 6: Voice Change
The human voice is more than just a tool for communication. It’s a signature, unique to every individual, crafted over years of experiences, emotions, and genetics. That’s why any unexplained change in the voice should be a cause for concern. A shift in voice texture, its resonance or its pitch, especially when prolonged, is not a mere vocal quirk. Often, it’s a silent alarm signaling that something might be awry deep within our respiratory system or surrounding structures.
Now, one might wonder: What’s the connection between the lungs and the voice? It’s a complex interplay of anatomy and physiology. The lungs, trachea, and larynx (voice box) form an intricate network. While the lungs aid in breathing, the larynx produces sound. Tumors or growths in the lungs can press against or irritate the nerves that serve the vocal cords. Such pressure or irritation can manifest as hoarseness or a distinct change in voice quality. The voice might sound raspy, strained, or there might be a notable decrease in volume, making one sound like they’re perpetually winded.
It’s natural to experience voice changes during a bout of flu or cold. But those changes are temporary, usually fading away as the illness does. However, when the voice alteration persists, outlasting any illness or apparent cause, it’s a reason for a deeper dive. Persistent voice changes can be an early symptom of lung cancer, especially when coupled with other symptoms, like a cough that doesn’t go away or unexplained weight loss.
While voice changes can indicate lung cancer, they aren’t exclusive to it. Numerous conditions, including benign growths on vocal cords, thyroid disorders, or even acid reflux, can alter the voice. However, the key is persistence. If the change remains for more than two weeks, especially if there’s no cold or apparent reason, it warrants further investigation.(6)
