Cancer is defined as the uncontrollable growth of cells that invade and cause damage to surrounding tissue. Oral cancer appears as a growth or sore in the mouth that does not go away. Oral cancer. Key words: Oral cancer, apoptosis, telomerase activity, LCM. More than 95% of the carcinomas of the oral cavity are of squamous cell type, in nature. They constitute a major health problem in developing countries, representing a leading cause of death. The survival index continues to be small (50%), as compared to th Mouth (oral) cancer is a major neoplasm worldwide and accounts for most head and neck cancers. Theoretically, it should be largely preventable or detectable at an early stage, given that the mouth is easy to access and examine by patients and healthcare professionals, assuming they have good lighting. [] Approximately 90% of oral cancers are SCC, which is seen typically on the lateral border. Cancer that occurs on the inside of the mouth is sometimes called oral cancer or oral cavity cancer. Mouth cancer is one of several types of cancers grouped in a category called head and neck cancers. Mouth cancer and other head and neck cancers are often treated similarly

of oral cancer (age-standardized rate of 11.0 per 100,000 men and women per year) (2) making it the most common cancer among men (men:women ratio 2:1) (3). Around 90% of the oral cancer cases are diagnosed as oral squamous cell carcinoma, therefore oral cancer is also used as a synonym to oral squamous cell carcinoma Oral cancers develop on the tongue, the tissue lining the mouth and gums, under the tongue, at the base of the tongue, and the area of the throat at the back of the mouth. Oral cancer accounts for roughly three percent of all cancers diagnosed annually in the United States, or about 53,000 new cases each year

In 2017, nearly 50,000 people will get oral or oropharyngeal cancer in the United States alone and more than 9500 of them will die from it, according to researchers at the American Cancer Society. 1 Doctors and researchers consider oral cancer particularly dangerous because this specific form of cancer comes with an unusually high risk of producing other cancers Introduction. Oral cancer (OC) is the commonest cancer in India, accounting for 50-70% of total cancer mortality and accounts for highest incidence among Asian countries [].OC is the sixth most common cancer worldwide [].It affects anterior tongue, cheek, floor of mouth, gingiva or any other part of the oral cavity What Are Oral Cavity and Oropharyngeal Cancers? Oral cavity cancer starts in the mouth. It might also be called oral cancer. Oropharyngeal cancer starts in the the middle part of the throat just behind the oral cavity that can be seen when the mouth is open. Cancer starts when cells in the body start to grow out of control Tongue cancer is a type of oral cancer that forms in the front two-thirds of the tongue. The National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) Program estimates there will be 17,960 new cases of tongue cancer in 2021.. As with other types of oral cancer, risk factors for tongue cancer include smoking, heavy alcohol use and HPV infections Microscopic Pathology. Microscopically, oral cancers are broadly based and invasive through papillary fronds.; Oral cancer constitutes of highly-differentiated squamous cells lacking frank cytologic criteria of malignancy with rare mitoses.The surface of the lesion is covered with compressed invaginating folds of keratin layers.; A stroma-like inflammatory reaction and a blunt pushing margin.

Pathophysiology is the study of the functional changes that accompany a particular disease. The pathophysiology of lung cancer is complex and still not completely understood; however, the understanding of the pathophysiology of lung cancer has advanced over time. Scientists have determined that lung cancer develops from a number of factors The current understanding of breast cancer etiopathogenesis is that invasive cancers arise through a series of molecular alterations at the cell level. These alterations result in breast.
