Oral Cancer and its Evolution

The other types of cancer that are possible to get are pharynx, larynx and esophagus cancers. These types of cancers will develop if the chewer decides to swallow the chew spit. Some danger signs of these types of cancer are: a prolonged sore throat, difficulty in chewing, and a feeling of something in the throat. Treating these types of cancer is a lot harder to cure and the user doesn’t really know until it’s too late!

A cancer cell is formed when the cell’s DNA is damaged but not repaired. Instead of the cell dying, like a normal cell, it reproduces new cells which also have the damaged DNA that the original cell had. Factors that can cause a cell to be damaged are mistakes during the reproduction of the cell, environmental reasons, such as smoking or too much sun exposure. The cancer cells form tumors which then invade the tissue of a certain body part, like the breast, lungs, brain, or prostate. Cancer can spread sometimes from body part to body part, but is named from where it starts. For instance, if somebody were to be diagnosed with breast cancer, and developed cancer in their lungs, it would be metastatic lung cancer. Metastasis is how cancer can spread to other body

What is cancer? This is an important question that will help people to understand the severity of this affliction. Cancer occurs from abnormal cell growth in the human body. When this happens tumors may form. Tumors are a mass of cells that continue to expand. These tumors may be benign. This means they will not spread through the body. Though, the tumors may be malignant which means they may spread to other areas of the body in an invasive manner. These malignant tumors have the potential to cause serious complications and even death. It is these tumors that are cancerous.

All cancers begin in cells, the body's basic unit of life. To understand cancer, it's helpful to know what happens when normal cells become cancer cells.

About 45,000 new cases of head and neck cancers are occurring every year in United States. Among them, estimated 20% are human papilloma virus (HPV) infected cancers. The tonsil, base of tongue and lingual tonsil, other potentially HPV-associated oropharynx, oral tongue, other oral cavity, larynx, and other HPV-unrelated oropharynx are all to be considered to be different part of head and neck cancer (HNC) in the study (Ryerson et al., 2008).

Cancer begins when cells in a part of the body begin to grow out of

Carcinoma is a cancer that begins to develop in epithelial cells. These cells include the lining or tissue of an organ or in the skin (Australian Institute of Health Welfare & Australasian Association of Cancer, 2012). There are two types of carcinoma cells, basal cells and squamous cells (American Cancer Society, 2012). Basal cell carcinomas are the cells that develop in the basal cell layer of the epidermis (American Cancer Society, 2012). Squamous cell carcinomas are cells that are more likely to develop in the fatty tissue beneath the skin (American Cancer Society, 2012). The squamous cell carcinoma are more likely to spread to the lymph nodes and surrounding tissues in the body (American Cancer Society, 2015.

Throat cancer Mt Pleasant TX is one of a number of cancers that are highly preventable and highly curable. According to The American Institute for Cancer Research, 63% of mouth pharyngeal and laryngeal cancers can be prevented by making simple lifestyle changes. But statistics that tout the preventability of a certain type of cancer are not much comfort after a diagnosis has been made. If you’ve been diagnosed with a type of throat cancer or you fear you’re at risk, here are some things you should know:

Remission- the reduction or disappearance of cancer signs and symptoms; may be partial (some) or complete (all) remission.

Head and Neck squamous cell carcinoma of oral cavity and oropharynx in children: Report of 10 cases and illustrated review of literature.

Oral squamous cell carcinoma is an invasive form of head and neck cancer, accounting for 94% of all oral cancers (Bagan et al., 2010). The common etiological factors associated are tobacco and betel quid chewing, human papilloma viral infections and alcohol consumption (Massano et al., 2006). Diagnostic delays have been reported to be an important factor responsible for progression of oral squamous cancers to advanced stages. The average 5-year survival rate for oral squamous cell carcinoma is 50% (Sciubba, 2002). Such invasive cancer is clinically preceded by a premalignant lesion which is associated with high malignant transformation risk.

Most salivary gland tumors are noncancerous (benign). However, cancerous tumors can spread from where it began to other parts of the body (it is called metastasis) through tissue, the lymph system, and the blood

2. Literatures Review 2.1. Oral squamous cell carcinoma (OSCC) Oral cancer (OC) includes a group of neoplasms affecting any region of the oral cavity, pharyngeal regions and salivary glands. However, this term tends to be used interchangeably with oral squamous cell carcinoma (OSCC) (Choi and Myers, 2008). Oral SCC is the most common malignant neoplasm of the oral cavity derived from stratified squamous epithelium including lips, buccal mucosa, lower and upper alveolar ridges, retromolar gingiva, floor of the mouth, hard palate, and the anterior two-thirds of the tongue (Lozano et al., 2013). By gross morphologic examination, the exophytic, ulcerative, or verrucous types are seen (Mehrotra and Yadav 2006). Regardless of the easy access of oral cavity for clinical examination, OSCC is usually diagnosed in advanced stages.

Salivary gland tumors are a morphologically diverse group of neoplasms, which may present considerable diagnostic and management challenges for the pathologist and surgeon. Salivary gland tumors are rare with an overall incidence in the western world of about 2.5 to 3.0 per 100,000 per year. About 80% of all lesions are benign; hence salivary malignancies are particularly rare, comprising less than 0.5% of all malignancies and about 5% of cancers in the head and neck. (1)

Let us take a look at cancers in the head and neck area. Researchers have long noted the link between smoking and increased risk of head and neck cancers including cancer of the oral cavity, pharynx, and the larynx. If one smokes, the risk of contracting mouth cancer is four times higher than for a non-
