Moles, birthmarks and other types of nevus
Moles, birthmarks and other types of nevus are spots or areas of skin that are darker than the surrounding skin. Some are flat, others are slightly raised. They may be there from birth, only develop later in life, and even disappear again. No treatment is needed. They only rarely turn into cancer.
Vocal nodules typically make your voice hoarse, and it may sound raspy and breathy too. These small non-cancerous growths usually go away again if you rest your voice or have voice therapy. They mainly occur in people who sing or speak a lot and loudly.
