Vocal polyps are noncancerous growths that develop on the vocal cords, often due to vocal strain, smoking, or allergies. They can appear as small blisters or bumps and may affect the quality of a person's voice, leading to hoarseness or a breathy sound. These polyps can occur in anyone but are more common among singers and individuals who use their voice extensively. Treatment typically involves voice therapy, lifestyle changes, or, in some cases, surgery to remove the polyps and restore normal vocal function.
