Biology Oral Cancer

All cancers have a genetic basis. It is then caused by mutation of the cellular gene causing abnormal cell proliferation. Many of these genetic changes are caused by random mutations when cells divide. It only requires cell mutations that can cause cancer. Cancer does not have any symptoms at first, and only 5% to 10% of cancers are caused by parents who pass genetic mutations to their children. The rest is caused by environmental change (Douglas). Cancer directly affects the life of about 1.37 million Americans.

Approximately 49,750 new cases of oral cancer are diagnosed every year in the United States. More than 9,750 people die in oral cancer each year in the United States. In the United States, oral cancer accounts for about 4% of all cancers and 2% of all cancer deaths. In Western Europe, oral cancer accounts for 2 to 6% of all malignant tumors. . In Asia, oropharyngeal cancer is the leading cancer in men, the third most common cancer among African and Asian women. The average 5-year survival rate of oral cancer patients is about 50%. This is mainly due to the slow discovery of the disease. Early detection and prevention is the key to fighting this deadly disease

Oral cancer is part of a group of cancers called head and neck cancer. Oral cancer occurs in the mouth and in any part of the oropharynx. Most oral cancer occurs from the tongue and the bottom of the mouth. Almost all oral cancer starts with squamous cells (squamous epithelial cells) covering the mouth, tongue and lips. These cancers are called squamous cell cancer. When oral cancer spreads (spreads), it usually spreads through the lymphatic system. Cancer cells entering the lymphatic system are carried by lymphatic fluids, clear, watery liquids. Cancer cells usually appear first in lymph nodes near the neck

Cancer is defined as uncontrolled proliferation of cells that invade and damage surrounding tissues. Oral cancer looks like growth and pain in the mouth and does not disappear. Oral cancer including lips, tongue, cheeks, mouth, hard palate and soft palate, sinusitis and throat (throat) cancer can be life threatening without early diagnosis and treatment. As part of your daily checkup, your dentist will perform screening tests on oral cancer. More specifically, your dentist will feel a change in lump or irregular organization in the neck, head, face and mouth. When you examine your mouth, your dentist looks for any pain or discolored tissue and checks for any of the symptoms and symptoms above.
