What causes mouth cancer?
The cause of mouth cancer, as with other cancers, is due to damage to cellular DNA. This results in uncontrolled growth of damaged cells, which leads to the formation of a cancer. The cancer can invade nearby tissues, or spread via the bloodstream or lymphatic system to other areas of the body. The exact cause of mouth cancers is not well known. However, certain risk factors are known to increase the risk of developing this condition. The major risk factors are smoking and excessive alcohol consumption.
