Symptom 3: Hoarseness or Voice Change – An Indication of Advanced MTC
Advanced stages of MTC can lead to hoarseness or voice change. The thyroid gland’s proximity to the voice box or larynx means that a growing tumor can exert pressure on the nerves that control the voice. This can result in noticeable changes to the sound and volume of the patient’s speech.
Hoarseness or a voice change often involves a raspy or strained voice, sometimes accompanied by a decrease in volume or a pitch change. The person might also experience vocal fatigue, where speaking for extended periods becomes strenuous.
Like the previous symptoms, a change in voice requires prompt evaluation. While voice changes can occur due to various reasons like viral laryngitis or overuse of the voice, persistent hoarseness may indicate a more serious underlying condition like MTC.
Specialists can assess voice changes using a variety of tools. One common technique involves direct visualization of the larynx using a laryngoscope, which provides real-time video of the voice box while the patient speaks or sings. Other imaging methods, like MRI or CT scans, might be employed to visualize a potential tumor affecting the laryngeal nerves.
Understanding this symptom is essential as it is often a telltale sign of disease progression. Early recognition and intervention can potentially halt disease progression and preserve the voice. Moreover, addressing voice changes promptly can significantly improve a patient’s quality of life, allowing them to maintain normal communication and social interactions. (3)
