Voice Change and Hoarseness
A change in the voice can be worrying, especially if it persists. People describe it in different ways — hoarseness, raspiness, a weak voice, vocal fatigue, loss of range, strain, breathiness, or a feeling that the voice is simply not right.
The good news is that most voice problems are not caused by cancer. Many are due to inflammation, voice overuse, reflux-related irritation, benign vocal fold lesions, muscle tension, infection, or age-related change. However, voice change can also occasionally be caused by more serious conditions, including cancer or wider medical problems, so a careful assessment is important.
In my practice, the aim is to work out exactly why the voice has changed and then tailor treatment accordingly. I run the multidisciplinary voice clinic at the John Radcliffe, Oxford, and I use the same principles in private practice. Where needed, I can also recommend excellent specialist speech and language voice therapists and voice coaches.
What can cause voice change or hoarseness?
There is a wide range of possible causes.
Some are relatively straightforward, such as:
laryngitis after a viral infection
voice strain or heavy voice use
smoking-related irritation
benign vocal fold lesions such as nodules, polyps or cysts
age-related thinning or bowing of the vocal folds
muscle tension affecting the way the voice is produced
Other causes are more structural or neurological, such as vocal fold weakness or paralysis, scarring, or other abnormalities of the voice box.
Voice change can also sometimes reflect wider medical or systemic issues, such as thyroid problems, inflammatory conditions, neurological disease, or general medical illness.
Stress can also have a very significant impact. In some people, stress does not just make a voice problem feel worse — it can actively contribute to muscle tension, throat tightness, vocal fatigue, and inefficient voice use. This is one reason why voice problems can sometimes become self-perpetuating, particularly in people who use their voice heavily or who are worried about the change in their voice.
And occasionally, persistent hoarseness can be a sign of laryngeal or other head and neck cancer.
When should a hoarse voice be assessed?
As a general rule, any hoarse voice or significant voice change lasting more than 3 weeks should be assessed, especially if there is no clear short-lived explanation such as a simple viral infection.
I am very happy to see patients with persistent hoarseness simply because they want a proper explanation and assessment. If there is any concern about cancer, the NHS has an urgent suspected cancer pathway which aims for specialist assessment within 2 weeks. If patients prefer to be seen privately, I am also very happy to see them urgently and ensure that the appropriate assessment and onward care are expedited, particularly where there is concern about cancer.
What are the red-flag symptoms?
Although most hoarseness is not cancer, there are some symptoms that deserve more urgent attention. These include:
a hoarse voice lasting more than 3 weeks
worsening or persistent throat pain
pain on swallowing or difficulty swallowing
coughing up blood
a neck lump
unexplained weight loss
breathing difficulty or noisy breathing
ear pain, especially if it is persistent and on one side
a significant smoking or alcohol history
Swallowing difficulties can also be closely related to voice problems. This is partly because the food pipe sits directly behind the voice box, so conditions affecting this area can sometimes cause both voice and swallowing symptoms together. For that reason, a history of both hoarseness and swallowing difficulty deserves proper assessment.
Why is a nasoendoscopy important?
A careful voice assessment usually includes a nasoendoscopy. This is one of the most important parts of the consultation.
A nasoendoscopy uses a very thin flexible camera passed gently through the nose to look at the throat and voice box in detail. It allows me to assess the appearance of the vocal folds and, just as importantly, how they move and come together when you speak. During the examination, you may be asked to make certain sounds so the voice box can be assessed properly.
This matters because two people can have the same symptom of hoarseness but for completely different reasons. One may have simple inflammation, another a benign vocal fold polyp, another vocal fold weakness, and another something more serious. Without actually looking at the larynx, it is impossible to make a proper diagnosis.
What investigations might be needed?
The first and most important investigations are usually:
a detailed history
examination of the ears, nose, throat and neck
sometimes a more specialist voice assessment
Depending on the findings, further investigations may sometimes be needed. These can include:
voice recording or acoustic analysis
stroboscopy or more detailed laryngeal imaging
blood tests if a systemic cause is suspected
scans if there is concern about deeper structures or nerve-related problems
biopsy or microlaryngoscopy if the vocal folds need closer examination under a general anaesthetic
Microlaryngoscopy allows the voice box to be examined in much greater detail while asleep, and also allows treatment or biopsy at the same time if needed.
How is voice change treated?
Treatment depends entirely on the cause.
For some patients, treatment is mainly medical. This may include managing reflux, treating infection or inflammation, adjusting medication, or addressing a wider underlying medical issue.
For others, the most important treatment is specialist speech and language therapy. Voice therapy can be extremely effective, especially for muscle tension dysphonia, inefficient voice use, some benign lesions, and rehabilitation after other treatments.
Some patients need surgery. This may include:
removal of benign vocal fold lesions
biopsy of an abnormal area
laser treatment to the vocal folds
procedures to improve closure of the vocal folds
treatment of a tumour or more serious structural problem
Can some voice procedures be done under local anaesthetic?
Yes.
Not all treatment has to be done under a general anaesthetic. Some procedures can be performed under local anaesthetic while you are awake. This is particularly useful in selected patients with vocal fold weakness, paralysis, or bowing.
One example is vocal cord medialisation or injection laryngoplasty. The aim is to move or bulk up the weaker vocal fold so that the vocal folds come together better when speaking. This can be a very effective option in the right patients.
What if the cause is cancer?
This is understandably one of the main worries people have when their voice changes.
Most hoarseness is not cancer. But cancer is one of the reasons a persistent voice change needs to be assessed properly rather than guessed at. If there is concern about a suspicious area in the larynx, the priority is to diagnose it quickly and plan the right treatment.
Why does specialist multidisciplinary assessment matter?
Voice problems sit at the point where anatomy, function and behaviour overlap.
Some patients need medical treatment. Some need precise phonosurgery. Some need speech and language therapy. Some professional or high-demand voice users may also benefit from input from an expert voice coach. Often the best outcomes come from combining these approaches rather than relying on just one.
That is exactly how I approach voice disorders in practice.

For general public information, the British Voice Association is a useful resource.
Voice-specific speech and language therapy is often an important part of treatment, and I can recommend excellent therapists and voice coaches where appropriate.
