Voice changes may indicate cancer, the UK National Health Service (NHS) has warned.

According to the Daily Express, experts recommend paying special attention to voice changes, as they can indicate serious problems.

Cancer can also be identified by a number of other symptoms: difficulty swallowing, unintentional weight loss, bleeding and numbness in the mouth, loose teeth, difficulty moving the jaw, and red and white patches on mucous membranes.

According to experts, a tumor in the oral cavity can develop on the inside of the cheeks, palate, lips or gums.

If you experience the symptoms described above, the NHS has advised you to see a doctor, but remain calm, as these symptoms may indicate other illnesses.
