Oral cancers can be easy to miss, as they usually begin as very small white or red spots or sores inside your mouth. It can affect your lips, tongue or the floor of your mouth, although the tongue is most common. Statistics show that around 25 to 30 percent of oral cancers are found in the tongue, 15 to 20 percent in the tonsils and 10 to 20 percent in minor salivary glands.
In some instances, however, oral cancer can even occur inside your cheeks, on your gums or in your palate. If left alone without treatment, oral cancer can cause severe damage, even death, which is why early detection is critical.
