Almost 263,020 oral cavity cancers, and 127,654 oral cancer deaths occur worldwide each year1. On January 1, 2010, in the US there were approximately 275,193 women and men alive who had a history of cancer of the oral cavity and pharynx (181,084 men and 94,109 women)2. The 5-year survival rate of patients with oral cancer remains almost unchanged despite various treatment improvements in the last three decades3. Individuals at high risk of developing oral cancer (OC) are mainly older, males, heavy users of alcohol and tobacco, and have a poor diet and low socioeconomic status4, 5. Recent studies have implicated HPV infection as an independent risk factor for oro-pharyngeal cancers6, 7. For oral squamous cell carcinoma (OSCC), the role of HPV remains controversial8.
OSCC initiates in a multi-step process in which normal cells are transformed into preneoplastic cells and then to cancer9. During this process a sequential accumulation of genetic and molecular changes occur10. The majority of oral cancers are preceded by visible changes of the oral mucosa. Within the oral cavity lesions such as leukoplakia, erythroplakia, lichen planus and submucous fibrosis have a propensity for malignancy11. Oral potentially malignant disorders (OPMD) transform to oral cancers through various histopathological stages from hyperkeratosis/hyperplasia, to various degrees of dysplasia (categorized by mild, moderate, or severe according to the presence and severity of cell atypia and other structural aspects of the epithelium), to carcinoma in situ (CIS), and finally to invasive cancer12. Histopathological assessment for the grade of epithelial dysplasia is the most common method to determine malignant potential of patients with oral pre-cancerous lesion...

...ociation between smoking tobacco, alcohol consumption and OPMDs. Second, our results may not be generalizable to the population at large, as only dental patients were included. Randomized-controlled trials may be useful to further investigate the sensibility and specificity of the oral visual examination in the context of OPMDs.
Optimal oral visual screening for OC remains a simple and essential tool to identify any suspicious lesions and potentially increase survival. A thorough visual and tactile examination in dental patients, particularly those with a history of smoking and elderly is warranted. Dentists should stay alert for signs of oral potential malignancy and counsel their patients about risk factors for oral cancer. Although OPMDs were rare, our results confirm the importance of a thorough chairside screening by dentists to detect any mucosal changes.
Initially she would perform the exams as learned in school, but now after finding something abnormal, she now does a more thorough check, especially on patients with previous history of cancer. This incident solidified her belief in early detection and proper documentation. By having the information in the patient’s chart Annette could refer back to it and follow up to see if anything has changed since the last visit. Most patients she sees do not have oral cancer but she is able to identify abnormalities and encourage the patient to have them checked to determine if they are precancerous.
However, on the a recent visit dated 23/12/13 the patient’s gingival condition had deteriorated, presenting with an increased plaque scores of 34% and bleeding scores to 63%. Intra oral examination also showed generalised oedema and erythema throughout in the mouth in response to this increase in plaque bacteria. The presence of supra-gingival calculus on lower anterior teeth and both sites of upper buccal molars and the patients BPE now reads 212 /121, putting the patients caries risk at a ‘High’ status.
Breast cancer has always been a common thread among the women of my family; especially on my mother’s side, including my Grandmother whom passed away due to this disease before I could ever meet her. More so, my mother was gravely affected by this disease early in my life. Thankfully, she was able to stop the cancer from spreading; the doctors were able to find the cancerous cells and remove them. Due to this grave, but powerful impact on my life, I have been determined to becoming a biomedical scientist to assist on the research and treatment of this deadly disease. Although this acts as my principal driver, to study in this field, I have also been intrigued and driven by the idea that I could aid lower setting regions to receive health benefits using studies in translational medicine and
The incidence of oropharyngeal carcinoma has been raised by 10.8% by 2004 since 1991. Distinctively, oroharynx cancer is prevalent biased toward men at least who are 50 years old of age than women. But this brings a new epidemiological concern because vast majority of men who has oropharyngeal squamous cell carcinoma (SCC) were HPV-positive. For example, the study conducted in, Colorado is experiencing 36.6% increased incidence rate of oropharyngeal caner. The HPV-related oropharyngeal SCC among men enhanced 12 times greater in past 20 years (Ernster et al. 2007). There is a declining rate in laryngeal cancer; however, there is sharp increase trend of cancer in tonsil and fairly stable rate in other HNC related cancer (Ryerson et al. 2008). However, decreased tonsillectomies in United States for past 40 years may be contributing to greater susceptibility of HPV in the tonsils (Ernster et al., 2007).
I have chosen to write about the constellation Cancer (The Crab). I chose Cancer because it is one of only a handful of constellations that I am actually able to identify in the night sky. Cancer is one of the twelve Zodiac constellations; people whose birthdays fall between June 21st and July 22nd have Cancer as their sign. Cancer is the Latin word for crab, and despite the fact that the constellation looks more like a lobster then a crab, it is still referred to as a crab. The constellation is visible from the northern hemisphere from late winter to early spring.
The body is composed of cells. Normally, these cells divide at a composed and calculated manner. If cells die or are destroyed, the body creates more cells through the division of existing cells. However, occasionally, problems with some cells in the body may occur.
Over 30,000 people are diagnosed with oral cancer in the US per year. Oral cancer is a cancer that is more common in people over the age of 45, but can occur at any age. Oral cancer can develop in any part of the mouth. “... Oral cancer- it is cancer that occurs in any part of the mouth; on the tongue’s surface, in the lips, inside the cheek, in the gums, in the roof and floor of the mouth, in the tonsils, and also the salivary glands”.(Salomon and Esposito; Dental Partners) Oral cancer, although devastating and destructive can be detected, prevented, treated and cured if it is found early on in its stages. Cancer is detected by dentist because there is a genetic mutation in the cell usually causing tumors within the initial area of effect. Oral cancer can be prevented, diagnosed and treated.
Cancer. The word by itself can conjure images of severely ill and frail people attached to IV medications and chemotherapy drugs as they cling to life in a hospital bed. Other illustrations and pictures depict unrecognizable, misshaped organs affected by abnormal cells that grow out of control, spread, and invade other parts of the body. Cancer studies show that close to one-half of all men and one-third of all women in the United States will be diagnosed with cancer during their lives. Today, millions of people are living with cancer or have had cancer. As patients are newly diagnosed with their specific type of cancer, whether it be breast, lung, prostate, skin, or blood cancer, etc., each patient has to consider what will happen with their future health care plan and who will be involved in their long journey from treatment to recovery. Once diagnosed, cancer patients become the focal point and the center of all activity in terms of care but cancer not only physically invades the patient’s body and well-being, it goes beyond the patient and significantly affects the emotional stability and support from from their loved ones and caregivers. Based on the insidious nature of cancer and typically late detection of malignant diseases, family members (either spouses, children, parents, other relatives, and friends) often become the patient's main caregiver. These caregivers, also known as informal caregivers, provide the cancer patient with the majority of the support outside of the medical facility or hospital environment and become the primary person to provide various types of assistance. They provide the physical support with bathing and assisting in activities of daily living, they become emotional ...
Cancer has been seen in humans as one the most potentially fatal disease for thousands of years and only in the recent couple of hundred years have we discovered that most information necessary to bring us to today’s understanding and knowledge (Kenny 2007, Weinberg 1996) was achieved by extensive research of cells, DNA, and epidemiology studies. As we know, currently cancer is acknowledged as having over a hundred different diseases, and is known to be the result of mutations of the genes and almost similar DNA which are responsible for the amount of cell division and production (Kenny 2007). Restraint of cell growth modulators can be a direct lead and result of certain tumours being developed and subsequently allow these tumours to acquire the ability to attack and occupy the bloodstream and essentially be able to travel via the bloodstream to other parts and organs in human bodies which is known as metastasis (Loeb et Al 2003). Once this has occurred , the cancer is then categorized as malicious and becomes a dangerous and serious threat to the carrier (Weinberg 1996). In this essay I will describe and explain the process of this and how our genes mutate and lead to metastasis of cancer cells.
Cancer has become a very common illness world wide for any age but mostly affecting adults. One can get cancer from different places in the body that is why there are so many people with cancer, because of all the different types. Cancer can affect any gender, female or male, and any age. It varies from ovarian cancer to prostate cancer, skin cancer to lukemia. Cancer has been a problem for many years yet we have not found a cure to treat and prevent cancer. If one is affected by cancer there are treatments to help take away this illness affecting their body. This essay is about a specific type of treatment for cancer, radiation therapy. There are different types of forms of particles for radiation, for example, protons and waves like x-rays and visible light. These types of radiations are grouped on how much energy they contain because it can cause different affects. A low type of energy radiation can be radio waves and heat, also known as non-ionizing radiation. Ionizing radiation has enough energy to break chemical bonds and knock electrons out of atoms, some examples of these are x-rays and ultraviolet light rays from the sun. That is why radiation is a way to treat cancer because of the strong energy it has to destroy a cancer cell, actually any cell in the body. That’s the issue with radiation therapy, is it worth the damage? It can damage any cell, wether it is healthy or cancerous, which can cause a major affect in the body later on. Although it sounds scary there are other types of treatments such as chemotherapy, targeted therapy, immunotherapy, photodynamic therapy, etc. So if radiation therapy does not sound like the best there are always other options but they do not develop the same results for radiation therapy. Rad...
Cancer has become the one of the most feared things for human beings. The various type of cancer have been discovered and there are still a lot of it that undiscoverable. Cancer is a complex disease that have a group of disease. The cancer itself cannot be describe by words. The causes of this cancer is still not being able to be discovered fully. There are only minor factor that can lead to this disease. The carcinogens are believed to be one of the causes that lead to cancer such as asbestos, radon gas, tobacco, PVC and much more from our chemical industries. The environment especially near to the industrial that produce chemical waste can be one of the causes lead to cancer. Cancer also have relation with our age, lifestyle, and diet and also can be genetically inherited. It is believed that older people have higher tendency to get cancer than younger people. Our lifestyle and diet also plays a role causing a cancer by our daily life routine. Smoking tobacco and eating unconsciously (still in research) can also increase the possibility to get cancer especially lung cancer that cause by smoking tobacco. There are several cases, cancer were inherited from their parents. Various type of viruses such as HIV, HPV, EBV and many more virus has a high capabilities to increase the chance a patient to get a cancer because these viruses lower their body immunity to disease.
“Just take my hand, together we can do it, I’m gonna love you through it.” (I’m Gonna Love You Through It- Martina McBride). Breast cancer is an awful disease that will change your life in a single moment. ”Everything in my life was turned upside-down. I really had a wonderful life; A husband, three children. And breast cancer came along and just smashed my world” (Janelle’s Journey). Breast cancer is an aggressive war that takes a great amount of fighting to survive. “You go from being perfectly healthy, to feeling like, ‘okay, I’m dying’. It started a whirlwind of things that I never anticipated having to go through.” (Bonnie’s Story- Beyond The Shock). Did you know that the youngest person ever to have been diagnosed with breast cancer
Cancer is a deadly disease that affects millions of American families each year. In cancer, cell division isn't controlled. Usually, cells have to go through a set of checks and balances before they divide, in cancer that is nonexistent. The cells just keep duplicating until they eventually form disorganized clumps called tumors. Tumors can either be, benign, meaning that they do not possess the power to metastasize to surrounding areas. If a tumor has the power to metastasize, it is classified as a malignant tumor. In simple terms, a benign tumor is not cancerous, and a malignant tumor is. Cancer cells cannot perform the necessary functions they were created for. Some types of cancers, like pancreatic cancer, cannot be cured. Other cancers such as melanoma and breast cancer have high survival rates when caught early. The four major types of treatments used to treat cancer include, surgery to remove the affected organ, radiation, chemotherapy, or biological treatments.
Over time as individuals age and are faced with access to care issues they may begin to neglect their oral health. As time passes between dental hygiene cleanings or dentist visits the presence of oral disease may begin to increase.
