Oral Cancer: Symptoms And Causes
Oral cancer occurs in different areas in the oral cavity or oropharynx. The types of oral cancer differ but most common occurrences in the form of sores and lumps can be found in the tissues of the mouth. Although in a majority of oral cancer cases the point of origin is the tongue, this form of cancer also occurs on the cheek lining, palate, gums, salivary glands, tonsils and floor of the mouth. It is extremely important to diagnose and detect oral cancer at an early stage to prevent the spread of cancerous cells from the point of origin to other parts. Detection of oral cancer at an early stage ensures that the treatment prevents the cancer from spreading and gives the individual an 80% chance of surviving.
Although the symptoms occurring in different forms of oral cancer are similar, they vary among individuals.
Symptoms of oral cancer
Lumps, sores, and ulcers occur in different areas of the lips, tongue and mouth. An early sign of development of oral cancer appears in the form of a reddish or whitish patch that surface on the tissues of the mouth. The size of the lumps or sores is usually small and painless in the initial stages but can get excruciatingly painful as the cancer develops. Sudden bleeding maybe experienced by some individuals. Individuals may experience difficulties in chewing and swallowing food. Individuals may find it difficult to move their jaw while talking. Loss of feeling or numbness accompanied by sudden bouts of pain in areas near the palate or cheek lining may occur. Individuals may suffer from severe sore throat and also experience changes in voice. Swelling of certain parts in the mouth such as tonsils or gums may occur among individuals. If the tumor is in an advanced state an individual may feel a burning sensation or excruciating pain. The colors of the sores or ulcers occurring in the tissues of the mouth are dark, colorless or pale in color.
Causes of oral cancer
There is no specific cause for the development of oral cancer. Although this type of cancer is high among men above 45, individuals at any age can develop oral cancer. The use of tobacco in its different forms is responsible for 75% of the oral cancer cases around the world. In a few Asian cultures where chewing beetle, paan and areca are prevalent, the risk of developing oral cancer is high. Non smokers are less likely to develop this type of cancer as compared to smokers. Individuals that are addicted to heavy smoking and drinking are at a higher risk of developing oral cancer than individuals that just smoke or drink. Research has proven that individuals who constantly use a mouthwash containing alcohol are at a significant risk of developing oral cancer. Constant exposure to the sun can also lead to development of lip cancer. The survival rate of oral cancer at a later stage is very low. Since there won't be any telling signs at the start it's best to resort to regular checkups so you can get a clear diagnosis at the very start.
