Cancers can be caused by DNA mutations (gene changes) that turn on oncogenes or turn off tumor suppressor genes. This leads to cells growing out of control. Changes in many different genes are usually needed to cause oral cavity and oropharyngeal cancer. For more about how genes changes can lead to cancer, see Genes and Cancer The etiology of oral SCC appears to be multifactorial and strongly related to lifestyle, mostly habits (particularly tobacco alone or in combination with betel, and/or alcohol use), [ 5, 6, 7] and..

In the throat, at the base of the tongue, where tongue cancer may develop with few signs and symptoms (hypopharyngeal tongue cancer)
. One area has clearly identified site-specific alterations of oncogenes such as EGFR and tumor suppressor genes such as p53 Oral cancer is one of the most common cancers and it constitutes a major health problem particularly in developing countries. It is one of the leading causes of death. Tobacco and alcohol consumption appears to be the major determinants of oral cancer. The literature search was carried out in NCBI. HPV can infect the mouth and throat and cause cancers of the oropharynx (back of the throat, including the base of the tongue and tonsils). This is called oropharyngeal cancer. HPV is thought to cause 70% of oropharyngeal cancers in the United States. It usually takes years after being infected with HPV for cancer to develop Oral cancer stems from a change in the DNA of cells that line the mouth or throat. These DNA changes may promote cancer by either creating genes that start cancer cell growth (called oncogenes) or turning off genes that normally stop cancer cell growth (called tumor suppressor genes)
INTRODUCTION• Oral cancer is one of the ten mostcommon malignancies in the world• In developing countries it constitutesthe 3rd commonest malignancy• Sites: lips and other intra-oral sitesbut Para-oral sites such as thesalivary glands, the oropharynx,nasopharynx and hypopharynx arenot normally included. 4 Oropharyngeal cancer is a type of head and neck cancer in which cancer cells are found within an area of your throat called your oropharynx. More than 90% of oropharyngeal cancers are squamous cell carcinomas, which are cancers arising from the flat surface cells lining your mouth and throat Cetuximab (Erbitux) is one targeted therapy used to treat mouth cancer in certain situations.

Smoking and drinking together further increases the risk of cancer more than either by itself. UK guidelines recommend a maximum of 14 units of alcohol a week for.
Causes of Oral Cancer. Oral cancer specifically is therefore caused by unwanted mutations, just like every other form of cancer, in the throat and mouth. These can occur purely by chance and may be outside the realms of what an individual can control. But at the same time, the likelihood of such mutations occurring may be increased by the. Causes. Oral or mouth cancer happens when cells within the oral cavity start abnormal mutation leading to an accumulation of abnormal growth of cells that slowly form a tumour. In the mouth, cancer usually starts as a painless white patch, that solidifies, develops red patches, an ulcer, and continues to grow.. High-risk HPVs can cause several types of cancer. There are about 14 high-risk HPV types including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68. Two of these, HPV16 and HPV18, are responsible for most HPV-related cancers.

Oral leukoplakia (OL) is a white patch or plaque that cannot be rubbed off, cannot be characterized clinically or histologically as any other condition, and is not associated with any physical or chemical causative agent except tobacco or areca nut.
