Vocal Cord

What Vocal Cords Are and How They Work

Vocal cords are two small bands of muscle located inside the larynx, or voice box, in your throat. When you speak or sing, air from your lungs passes through the vocal cords, causing them to vibrate and produce sound. Each person's voice is unique because of the size, shape, and tension of their vocal cords. Healthy vocal cords are essential for clear speech and singing.

Why Vocal Cords Matter in Cancer Care

Because vocal cords are key to making sound, any damage or disease affecting them can change your voice. In cancer care, vocal cords may be involved if cancer develops in the larynx or nearby areas. Sometimes, surgery called a cordectomy is used to remove part or all of the vocal cords to treat cancer. This surgery can permanently change your voice, often making normal speaking impossible after total removal. Understanding the role of vocal cords helps patients and caregivers prepare for possible changes and discuss treatment options with their care team.

Signs of Vocal Cord Problems and Common Causes

Voice changes can signal vocal cord problems. Signs include a hoarse or raspy voice, losing the ability to hit high notes when singing, a sudden deeper voice, a raw or achy throat, or difficulty talking. Causes range from infections and acid reflux (when stomach acid moves up into the throat) to growths caused by viruses, cancer, or diseases that paralyze the vocal cords. Early diagnosis and treatment can often improve voice problems.

What Patients Might Hear About Cordectomy and Voice Changes

Cordectomy is a surgery that removes part or all of one or both vocal cords, often to treat laryngeal cancer. The extent of vocal cord removal affects how much the voice changes. After total cordectomy, most normal speaking sounds are lost, though whispering and some deep sounds may still be possible. Patients may be introduced to alternative ways to communicate, such as electrolarynx devices or speech therapy. It’s important to discuss with your care team how this surgery might affect your voice and daily life.

Where You Might See the Term Vocal Cord

The term vocal cord may appear in medical reports, treatment plans, or discussions about symptoms or surgery. It can also show up in clinical trial information or drug details when treatments involve the voice box or related areas. Knowing what vocal cords are and their role helps you understand these materials and ask informed questions.

What Vocal Cord Does Not Automatically Mean

Hearing the term vocal cord does not mean you have cancer or a serious problem. It simply refers to the muscles in your voice box that help you speak. Voice changes can have many causes, not all related to cancer. Always ask your care team what the term means in your specific situation.

Questions to Ask Your Care Team

If you hear about vocal cords in your care, you might ask: What is causing my voice changes? How will treatment affect my voice? Are there ways to protect or improve my vocal cords? What communication options are available if my voice changes? Understanding these answers can help you prepare and cope with changes.
