Esophageal Cancer
The human body consists of millions of living cells. These cells grow, divide and die. This process goes on in our body without us even knowing it is happening. Our body is an amazing creation that scientist still can’t completely explain how and why all things happen. When our bodies are younger our cells divide faster which lends to our bodies growing. As we become older this process slows down and usually only divides to repair or replace old or injured cells. When cells begin to grow out of control this causes abnormal cell growth. The growth of these cells, start to take over other tissues, something that the normal cells can’t do. The growth and taking over the cells is what then begins the start of cancer cells. Depending on where this growth occurs depends on where the cancer begins to grow. The cells turn into cancer cells because the DNA becomes damaged. Usually when DNA is damaged our cells repair the damage, but with cancer these cells can longer be repaired and the cell is not able to die like it normally would. Then the damaged or sick cells start to grow and carry on the damaged DNA. This then begins the process of cancer.
It is not fully understood how and why these cells become damaged and cancer sets in. But what we do know is that the damage to the DNA is usually caused by mistakes that happen while the normal cell is reproducing or by a cause in our environment. Exposure to obvious things like smoking and alcohol are clearly risk factors to cancer. However not all types or cases of cancers can be linked to the environment or exposure to high risks. In the instance of esophageal cancer it is believed that their are certain risk factors that are common contributing factors in this disease.
According to the American Cancer Society, Scientists believe that some risk factors, such as the use of tobacco and alcohol, may…...

...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......

...What is Cancer? What is Cancer? Cancer is a disease that is caused by an uncontrolled division of abnormal cells in part of the body. In the U.S. more than thirty four hundred people get diagnosed with cancer every day, and according to the statistics one out of three people will be affected with cancer at least once in their life. Cancer is one of the most deadliest killers in the U.S. and other countries as well. As you read my essay you can tell that this is all facts, in this essay I will discuss cancer and the effects it had on my aunt Millie and my family, symptoms, and risks. My aunt’s struggle with cancer was one of the many things I couldn’t stand to watch, but then at the same time I had to. My aunt’s daily activities after she found out about the cancer did not change she still cooked and cleaned even though sometimes she needed some help. My aunt never felt sad or angry that she had gotten cancer she would wake up every day and make the best of it she was always happy no matter what. The day my aunt Millie passed away was one of the saddest days our family has ever went through. Everyone in our family loved her so much and never wanted to see her go, but every day when I think of her I know that she is in a better place.

...Iran Med 2010; 13 (2): 143 – 146 Mini Review Five Common Cancers in Iran Shadi Kolahdoozan MD MPH*, Alireza Sadjadi MD MPH**, Amir Reza Radmard MD***, • Hooman Khademi MD MPH * Iran as a developing nation is in epidemiological transition from communicable to noncommunicable diseases. Although, cancer is the third cause of death in Iran, it`s mortality are on the rise during recent decades. This mini-review was carried out to provide a general viewpoint on common cancers incidence in Iran and to explain incidental differences that may help us to establish early detection programs and investigate population risk factors. A detailed PubMed, Scopus and Google scholar search were made from 2000 to 2009. The basic inclusion criteria were all relevant studies focused on cancer epidemiological data from Iran. Overall age-standard incidence rate per 100 000 population according to primary site is 110.43 in males and 98.23 in females. The five most common cancers (except skin cancer) are stomach, esophagus, colon-rectum, bladder and leukemia in males, and in females are breast, esophagus, stomach, colon-rectum and cervix uteri. The incidence rates of gastrointestinal cancers are high in Iran (it is one of the known areas with a high incidence of GI cancers). Breast cancer mainly affects Iranian women about a decade earlier than Western countries and younger cases are affected by an increasing rate of colorectal cancer in Iran, near the Western rates.

...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. Scientists are sure there are many more they just have not yet been diagnosed. The cancers that are most...

...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......

Lung Cancer

...What is Lung Cancer? Lung cancer is cancer that usually starts in the lining of the bronchi (the main airways of the lungs), but can also begin in other areas of the respiratory system, including the trachea, bronchioles, or alveoli. It is the leading cause of cancer death in both men and women. Lung cancers are believed to develop over a period of many years. Nearly all lung cancers are carcinomas, a cancer that begins in the lining or covering tissues of an organ. The tumor cells of each type of lung cancer grow and spread differently, and each type requires different treatment. “About 85 percent to 90 percent of lung cancers belong to the group called non-small cell lung cancer” (University Hospitals, 2011). Lung cancers are generally divided into two types: Non-small cell lung cancer is much more common than small cell lung cancer; Small cell lung cancer, sometimes called oat cell cancer because the cancer cells may look like oats when viewed under a microscope, grows rapidly and quickly spreads to other organs. It is important to find out what kind of lung cancer a person has. The different types of carcinomas, involving different regions of the lung, may cause different symptoms and are treated differently. Lung cancer usually does not cause symptoms when it first develops, but they often become present after the tumor begins growing .Each individual may experience symptoms differently .A cough is the most common symptom of lung cancer. Other symptoms include:......
