Michael Ho, an oncologist specializing in malignant tumors of the head and neck, said that the appearance of ulcers, discoloration and swelling of the oral mucosa, chronic cough and loose teeth can be signs of cancer development. In this respect reports Daily mail.
The most common symptom of oral cancer is ulcers that do not heal within three weeks, the doctor said. They can appear on the tonsils, base of the tongue, soft palate, and back of the throat. Ulcers can also be caused by human papillomavirus (HPV). Unexplained, painful swellings around the mouth or jaw may also indicate the development of cancer. Sometimes swellings appear on the surface of the tongue, lips or gums.
Cancer symptoms may also appear as red or white spots. The appearance of white spots is called leukoplakia, and the appearance of red spots is called erythroplakia. They can also be symptoms of a fungal infection called thrush.
Another non-obvious sign of the development of malignant tumors may be loosening of the teeth. Inflammation of the oral mucosa can cause swelling and loosening of gum tissue. It does not adhere tightly to the surface of the teeth, causing them to loosen.
For chronic sore throat, cough and voice changes, it is worth consulting an ear, nose and throat specialist. Chronic cough is defined as a cough that lasts longer than six weeks. The development of tumors in the mouth can cause slurred speech, make certain words difficult to pronounce, or cause pronunciation to become blurred.
