Oral Cancer: Who's at Risk?

Historically, most of the patients are above 40 years of age at the time of discovery of oral cancer. Aging is an important factor because the immunity diminishes with age as well as there are increased chances for the cells turning from benign to malignant tumor cells. This is further supported by the fact released recently in 2008 which says that oral cancer exists even among the non smokers who are below 50 years of age.

Predominantly the cause for oral cancer is attributed to the factors like the use of tobacco, consumption of alcohol and infection by Human Papilloma Virus (HPV). Among all these different causes, tobacco is considered to be the primary culprit although it takes a long time to get precipitated into an oral cancer. Especially the people who are above 50 years of age are widely affected and more than 75% of those people are constant users of tobacco. Tobacco in combination with alcohol is even more harmful and the chances are 15 times more for oral cancer if a person is addictive to both tobacco and alcohol. Recent reports also suggest that the demographics are changing rapidly as the incidence of oral cancer caused by viral infections is increasing day by day.

The factors for the cause of oral cancer can be grouped as physical factors, chemical factors and biological factors. Alcohol and tobacco comes under chemical factors. Ultraviolet (UV) rays and x-rays are the major physical factors responsible for causing oral cancer. UV rays cause lip or skin cancers. Radiographs in x-rays can cause various types of neck or head cancers. Now days, there is more awareness towards physical factors and the percentage of people getting affected by this has drastically reduced over the past few decades.

Biological factors indicate the fungi and the viruses which has a major link towards causing oral cancer.…...

...Losing Someone to Cancer In Emily Dickinson’s poem, “accustomed to the dark”, she describes going through hard times when losing a special person and knowing everything will be okay as things “Adjust itself to midnight and life steps almost straight.” She sets up a situation where losing someone to a life threatening situation or a disaster. It’s easier to ignore the truth and live in fear but once we get over our doubts, though it’s difficult we can change the darkness to light. We can live in truth and in goodness but it is scary, suffer through much and sometimes there are consequences but living the right way in truth without fear is worth the journey of getting there. It all began in July 2005 when she was 45 years old. I remember walking in the front door after school and seeing my aunt crying. I was completely shocked, as I had never seen her cry before. She then sat me down and explained to me that she had a number of tumors. At first this didn’t mean much to me as I was too young to understand the extent of her illness, but as time went on I slowly began to understand. “A moment we uncertain step for newness of the night.” As time passed she became quite sick, and was soon transferred to a hospital. Sadly a few years after that, she passed away after putting up a strong fight for just over 15 months. It took me a while to come to terms with my aunt’s death; however the support given to me from my friends and family helped me tremendously. For the following......

...Breast Cancer Tonia Maraden CM220-51 November 23, 2012 Breast Cancer Debra Wheeler is a wonderful person and a personal friend that works with me at my part time job. She is the Executive Assistant to the CEO. In January of last year, Debra Wheeler was diagnosed with Stage 2 breast cancer. She ended up having to have single mastectomy since the cancer was only in one of her breast. She then later had to have the breast the removed and reconstructed. The way they did it was take the skin and soft tissues from the belly and use it to reconstruct her new breast. Debra’s healthy body and her positive spirit helped her to beat the cancer, now she has been cancer free for a year. She is a very strong willed person and that is why I believe is the reason that she is still here today others have not been so lucky or gave up the fight too early. With this in mind, Debra has discovered along with many breast cancer survivors that the oral contraceptives for many years were a possible cause to the reason they were diagnosed with cancer. There are more than one reason has to why we should support breast cancer. Breast cancer is something that will or has affected us all in one way or another. I.

Oral Health

...Practicing Oral Health i. Why did you choose this health behavior? The main reason I choose this behavior is because I think taking care of your mouth is the upmost important thing to do as it can affect other parts of your body. I have always taken care of my teeth to avoid the dentist as much as possible and keep cavities at a bare minimum. Oral hygiene is important to keep up with because nobody wants to have rotten teeth. We all want a perfect smile without stained or cavity filled teeth so why not take care of them right the first time so never have to get false teeth. For me, oral hygiene is one of the first things I ever think of and I hope other people feel the same so they can have long lasting teeth and avoid the dangerous cancers and gum diseases. The potential epidemiology of oral hygiene can always lead to a disaster of things by simply ignoring it or putting things in a mouth that causes negative health issues. The epidemiology of oral health is influenced by age, sex, origin which is associated with oral cancer risk and established risk factors including alcohol and tobacco use, for example. Additionally, possible associations between oral cancer risk and oral hygiene, diet, nutritional status, and sexual behavior as well as the influence of genetic factors on oral cancer risk are considered (NIDCR Home). Oral health also has an effect on other persistent diseases. Because of the failure to tackle social and material determinants and incorporate......

...Oral Cancer: The Quiet One Imagine for a moment being silent. Imagine having the words to say, but no means to make them heard. Try to envision your life without being able to taste your favorite foods, or perhaps never being able to eat them at all, even though they might be readily available. Picture having all the water you could ever desire, but never being able to quench your thirst. It sounds something like hell, doesn’t it? This isn’t just some make believe version of hell; it is a harsh reality of our world. Each year, thousands of people will experience this nightmare for themselves. “Why?” you may ask. It is all caused by an easily detectable form of cancer: oral cancer. When identified early, the disease can be easily treated and rarely requires radiation or chemotherapy. However, very few people actually get checked for oral cancer, despite the fact that it could save hundreds if not thousands of lives each year. One of the least publicized forms of the disease, oral cancer has very few signs or symptoms in its early stages, can easily and rapidly spread to other areas of the body, and has an extremely high mortality rate. In the early stages of oral cancer, there is often no initial pain. It is difficult to detect without a detailed familiarity with your own body or an experienced professional’s examination. Self examinations can be helpful, but since the mouth often has various bumps and lumps appearing and disappearing, the beginnings of oral......

...Breakdown of Cancer Breakdown of Cancer Cancer is introduced when a single mutated cell begins to reproduce abnormally. According to Lee Copstead and Jacquelyn Banasik, cancer is a malignant neoplasm or new uncontrolled growth of invasive cells. Cancer begins when cells break from normal cell division that follows its own path. This is known as proliferation, which is abnormal cell division. According to (Copstead & Banasik, 2010) cancer develops when proto-oncogenes become inappropriately activated and this change is due to mutation in the cell’s (deoxyribonucleic acid) DNA. Furthermore, cancer is an out of control cell growth. For a patient to receive an accurate diagnosis of cancer a through history and physical examination has to be done. There are many tests necessary to diagnosis cancer. According to Copstead & Banasik, 2010) the definitive diagnosis of cancer is a positive cytological or histological result. Cytological is the microscopic finding of pathological cells. This can be done by aspiration or exfoliate. Whereas histological is the examination of cells by staining and examining sections of tissue. Other diagnostic tests, such as imaging, chest radiography, computed tomography (CT scan), mammography, or (positron emission tomography) PET scan. There are numerous laboratory test that can aid in the diagnosis of cancer. Urinalysis is used detect blood or hematuria that could be an indicator for bladder cancer. Tumor markers are......

...diagnosed with cervical cancer. 12,042 women in the United States were diagnosed, and my sister Amber unfortunately, fell under that statistic. At the time she did not have medical insurance and Amber had not been in for a routine check up in over three years. It was not until she had to go to the hospital for severe pain in her abdomen, when doctors discovered a cyst on one of her ovaries, her lack of urgency eventually cost her health. Amber was diagnosed with stage zero Cervical cancer in early August, This being one of the earliest forms, cancer cells are found on the surface of the cervix. During this time there was a lot of waiting and anxiety my sister and our family went through. Amber had many doctor appointments and went through some very painful procedures such as, a Colposcopy biopsy and an Endometrial biopsy. Being the supporting, loving, and helpful family we are, everyone was by her side every step of the way and helping care for her son while she had Doctor appointments. Since then it has greatly impacted her and our family on the way we live life, It brought everyone together, from taking her to appointments, to helping with her child, it showed how quickly everything can change.

...NEW TREATMENTS FOR CANCER A new revolution for cancer therapy has been created which is called “molecularly targeted therapy”. Since most drugs kill healthy cells along with cancer cells and cause serious side effects, this therapy will only kill the cancer cells of a specific cancer type. They are designed at the molecular level of the cell and are also able to identify specific molecules that are unique to specific cancers. One of the most eligible drug is called glivec, (also known as STI571) actively effecting a form of leukemia called chronic myeloid leukemia that causes excess overproduction of white blood cells. Moreover, in a case study it is reported that a gastroiestional stromal tumor was treated with STI571 and resulted in a significant reduction of the tumor. As this therapy promises the health of the patient, it also has some negative impacts and some limitations. Since this drug is specific to a small amount of molecules, it is not relevant to a large amount of tumors, meaning it is very limited in its application. Furthermore, the patients may experience diarrhea and liver problems such as hepatitis and elevated liver enzymes. All in all, molecularly targeted therapies hold the promise of harming fewer cells, reducing side effects and assuring a healthier life. Another new advancement in cancer treatments is called “immunotherapy”. This therapy is developed to enhance the immune system to fight cancer, reducing all severe side effects.

...Cancer Cancer is the uncontrolled growth of abnormal cells in the body. Cancerous cells are also called malignant cells. Causes, Incidence, and Risk factors Cells are the building blocks of living things. Cancer grows out of normal cells in the body. Normal cells multiply when the body needs them, and die when the body doesn't need them. Cancer appears to occur when the growth of cells in the body is out of control and cells divide too quickly. It can also occur when cells forget how to die. There are many different kinds of cancers. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue. There are many causes of cancers, including: * Benzene and other chemicals * Drinking excess alcohol * Environmental toxins, such as certain poisonous mushrooms and a type of poison that can grow on peanut plants (aflatoxins) * Excessive sunlight exposure * Genetic problems * Obesity * Radiation * Viruses However, the cause of many cancers remains unknown. The most common cause of cancer-related death is lung cancer. Some cancers are more common in certain parts of the world. For example, in Japan, there are many cases of stomach cancer, but in the United States, this type of cancer is pretty rare. Differences in diet may play a role. Some other types of cancers include: * Brain cancer * Cervical cancer * Hodgkin's lymphoma * Kidney cancer * Leukemia * Liver cancer ...

...Cancer is the second-leading cause of death and disability in the world, behind heart disease, according to the American Cancer Society. Medical research is needed to help fight cancer so cancer patients can live longer and happier, lives. The only way to uncover new treatments for cancer is to continue to invest in the work of scientists and physicians who have already helped in this field so far. The American Cancer society strives to eliminate cancer by extensive research and provides knowledge worldwide about cancer. Research shows that cancer has the most devastating economic impact of any cause of death in the world. More people die from cancer every year around the world than AIDS, tuberculosis and malaria combined. Cancer is a global challenge. . Investment in research through the American Cancer Society (ACS) drives new and better ways to prevent, detect and treat cancer. The five-year survival rate for all adult cancers combined is 68 percent; an increase of 18 percent since 1975. During the past 30 years, 153 new FDA-approved medical advances were discovered through research carried out in a federally funded lab or institution. Forty of those innovations were new therapies for cancer. Investing in cancer research not only saves lives but also, the progress against cancer will yield dramatic savings. (ACS) According to the National Cancer Institute, cancer costs are projected to reach at least $158 billion in 2020. The (NCI) states that the projections were......

...the case with cancer. More and more people die everyday from cancer and it appears to ruin the lives of all those associated with it. What people need to understand though is yes cancer is a life altering chain of events but cancer is not the end of the world. Death is inevitable; there is no way around it. Perhaps cancer patients realize this more than anyone. “All creatures born upon this earth must, in the end, die. Some live long and peaceful lives. But others are caught up in struggles—must fight for their lives” (Silverstein 12-13). This is the case with cancer. Cancer patients will struggle and fight for their lives and not have the luxury of dying peacefully. The cause of cancer is still unknown to scientists but they have been able to come up with some possible explanations. Cancer affects newborn babies, boys, girls, women, men, animals and even plants. The possible causes of the cancers that affect each of these groups include chemicals in the body, viruses, ultraviolet rays, smoking, and it has been proven to be hereditary in some cases. Many people who develop cancer have had repeated or prolonged contact with one or more of these cancer causing agents (Silverstein 27). With the many different types of cancer it may, for some people, seem impossible for scientists to discover a cure. Skeweris 2 There are more than one hundred known types of cancer.

...Cancer is as a disease when cells divide uncontrollably, involving unregulated cell growth. Ever cell in your body contains DNA (deoxyribonucleic acid) every DNA contains information about how to grow and what kind of cell it is. When DNA gets damaged it fixes itself with creating new strands but if it’s damaged beyond repaire it dies out. Some times the damaged DNA does not die but continue to multiply and make new copies even though that its damaged and not needed anymore. This Damaged cell leads to the malformations called as mutation. This mutation is further grown uncontrollably causing tumors in the body and is slowly spread into other parts of the body. If untreated can cause death. There are many causes of cancers such as Benzene and other chemicals, toxins, drinking excess alcohol, Excessive sunlight exposure, Genetic problems, obesity , viruses, radiations, Workplace Carcinogens The statistics shows that An estimated 186,400 new cases of cancer (excluding about 81,300 non-melanoma skin cancers) and 75,700 deaths will occur in Canada in 2012. In 2007, cancer surpassed cardiovascular disease (heart and cerebrovascular) as the leading cause of death in Canada. In 2012 approximately 88.800 Canadian women will be diagnosed with cancer, and an estimated 36,200 women will die of cancer.  Approximately 97,600 Canadian men will be diagnosed with cancer, and an estimated 39,500 men will die.

...Cancer is a disease that begins in the cells of the body. In normal situations, the cells grow and divide as the body needs them. No more, no less. This orderly process is disturbed when new cells form that the body were not needed and old cells don't die when they should. These extra cells lump together to form a growth or tumor. Understanding tumors Two types of tumors exist, benign and malignant. Benign tumors are not cancerous. They can usually be removed and generally don't grow back once they're gone. The cells in benign tumors don't spread and it is rare for a benign tumor to be life-threatening. Malignant tumors, on the other hand, are cancerous. The cells in them are abnormal and divide randomly and chaotically. The cells behave aggressively and attack the tissue around them. They also can jump away from the malignant tumor and enter the bloodstream or lymphatic system to form new tumors in other parts of the body. This type of spread is known as metastasis. Types of cancer There are virtually dozens of different cancer types. The most common in the US is a non-melanoma skin cancer. Close to one million new cases of it were reported in the US in 2005. Breast, lung and prostate cancer also are very common. Effects of cancer A cancer diagnosis permanently changes your life -- sometimes surprisingly for the better and other times with dire consequences. You are suddenly faced with hundreds of decisions, from choosing a doctor, to considering different......
