Oral cancer is defined as the abnormal growth of cells in any part of the lips or mouth. Most oral cancers are known to commence in the lips or mouth lining. This is the region where we find the flat cells also known as the squamous cells. Other names for this type of cancer are oropharyngeal cancer and oral cavity cancer. There is a wide range of risk factors associated with oral cancer. This involves heavy alcohol consumption, smoking, having human papillomavirus (HPV), or marijuana usage. In case of lip cancer, exposure to UV light or tanning beds increases the risk for oral cancer. Symptoms include lumps or sores on the mouth region or the lips.
The diagnosis begins with the doctor conducting an oral screening exam as part of your routine dental exam. In specific terms, your dentist will try to find out the irregular changes of tissues in your oral cavity, neck, face, and head, or feel for lumps at the same areas. During the oral examination, he will look for discoloured tissues or sores. You may also require a biopsy to determine any suspicious looking areas. The treatment methods available for oral cancer are the same as any other cancers. Firstly, it involves a surgery to remove the cancerous growth of cells, followed by a chemotherapy or radiation therapy to fully remove the remaining cancerous cells.
