Cancer is one of the most common causes of death worldwide. It is a disease that begins as a renegade human cell over which the body has lost control. Since cell is involved, these we call ‘cancer cells’ continue to divide and multiply at their own speed which may form abnormal lumps or tumors. There are many types of cancer such as lung cancer, breast cancer, and brain cancer. Being a widely known cause of death, researches and experiments about cancer prevention or treatment have been presented. Cancer immunotherapy is the use of the immune system to reject cancer which is done by attacking the malignant tumor cells that are responsible for the disease. This can be either through immunization of the patient (e.g., by administering a cancer vaccine), in which case the patient’s own immune system is trained to recognize tumor cells as targets to be destroyed; or through the administration of therapeutic antibodies as drugs, in which case the patient’s immune system is recruited to destroy tumor cells. Antibody, also known as an immunoglobulin, is a large protein secreted by a plasma cell to be used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. Monoclonal antibody therapy is the use of monoclonal antibodies (or mAb) to specifically bind to target cells or proteins. This may then stimulate the patient's immune system to attack those cells. mAb therapy can be used to destroy malignant tumor cells and prevent tumor growth by blocking specific cell receptors. Antibodies are a key component of the adaptive immune response, playing a central role in both in the recognition of foreign antigens and the stimulation of an immune response to them. It is not surprising therefore, that many immunotherapeutic approaches involve the use of antibodies. The advent of monoclonal antibody technology has made it possible to raise antibodies…...

...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. Cancer today is one of the most deadly killers in the world. There are many different types of cancer lung cancer, breast cancer, colon cancer, prostate cancer, etc. There are many different signs of having cancer a change in bowl/bladder......

...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......

...SUMMARY: The story is all about a guy who develops lung cancer because of smoking for almost years. This guy is consume for almost packs of packs of cigarette all the time, like when he is doing some chores in their house, after eating and even in his vacant time. Smoking becomes his hobby and it was also part of his daily activity. He also drinks alcohol with his friend, he’s lifestyle was very unhealthy and he’s not doing any physical activity aside of doing chores. So then after few years of continuous smoking of cigarette plus unhealthy lifestyle, the patient began to experience several symptoms and realize that something was wrong with him. He noticed that he’s having a barking cough always. One day while the patient is resting, he started to cough at the same time with difficulty in breathing. Then his relatives send him in the hospital, then the nurse immediately gives him oxygen. To ensure the condition of the patient, there are a lot of diagnostic exam done to the patient, as the result, the patient had lung cancer. He was hospitalized for few months but then the patient died because of complication.

Cancer itself has been all in the news, newspapers, within the past couple of years and seems it is taking over more so than Aids. Depending on what type cancer it can be fatal for the person and their family or just hearing the word is devastating itself. There are different types of cancers that are divided by the type of cell that is affected. when the cells uncontrollably form masses or lumps of tissue that are called tumors, The body is most at harm, which can expand and damage the nervous and digestive systems. The tumor that stays in one particular spot without any type of movement is called benign, and the more serious form that over takes the body is called malignant. Malignant tumors uses the blood system to invade the healthy tissue that is already present. Another tumor which spreads itself throughout other parts of the body and it is a success it is said it has metastasized, which is very serious and difficult to treat. In 2007, 7.6 million people lives have been claim by cancer. ------------------------------------------------- Treatment of......

...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. Your cells are giving a life span, when they die new cells are developed to replace the ones that have died, but that is not always the case.

...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.

Approach to Care of Cancer

...Approach to Care of Cancer Ahmed Grand Canyon University Pathophysiology and Nursing Management of Clients' Health NRS-410V February 21, 2016 Cancer is affecting people of all races and it is everywhere into world. It is estimated that, a total of about one million five hundred thousand people are found to have cancer every year (Ignatavicius, 2010). Cancer is a genetic disease and it is referred to as the collection of related diseases that involves abnormal cells that continue to divide without stopping and spreading to surrounding tissues (Ignatavicius, 2010). Cancer is a common disease today, but it is not a new disorder. Some types of cancer happens to be more common today among certain group that are considered affluent. This is happening because of the long life expectancy and increase exposure to substances that causes cancer. Determining the cause of cancer can be complex, even though more advanced technology have made it much better now to diagnose the disease. Studies have shown that obesity, tobacco use, environmental pollutants, certain diet increases the risk for cancer (National Cancer Institute, 2014). The symptoms of cancer can vary depending on where the cancer is formed, where it has spread and the size of the tumor. The fear of dealing with the disease causes stress and depression for the patient. Understanding the prognosis of cancer is important when planning a variety of options for treatment (National Cancer Institute, 2014). This paper will......

...Cancer: Cancer can be defining as disease condition in which cell divide and proliferate uncontrollably bypassing the normal rules of cell division. It is characterized by a progression of changes on cellular and genetic level that ultimately reprogram a cell to undergo uncontrolled cell division, thus forming a malignant mass. Carcinogenesis: Cancers consist of single clones or several clones of cells that are capable of partially (benign tumor) or fully (malignant cancer) independent growth in the host. The essence of carcinogenesis is the activation (deregulation) of genes that regulate cell growth via bypassing the host’s regulatory circuits. Multiple genes must be deregulated for the development of fully malignant tumors What causes cancer? Physical, chemical and biological agents may cause cancer. Cancer arises from the mutation of a normal gene. Mutated genes that cause cancer are called oncogenes. Carcinogens: Radiations: Ultraviolet light, X-rays, radioactive elements induce DNA damage and chromosome brakes. Chemicals: smoke and tar, countless chemicals that damage DNA (mutagens Oncogenic viruses: insert DNA or cDNA copies of viral (v) oncogens into the genome of host target cells. Hereditary: certain oncogenes are inheritable. Classification of cancer Benign tumor: do not spread from their site of origin, but can crowd out surrounding cells e.g. brain tumour, warts. Malignant tumours: can spread from the original site and......

Badder Cancer Treatment

...Bladder cancer treatment(s) and pre/post nursing care:pg.1702 Therapy for the client with bladder cancer usually begins with surgical removal of the tumors for diagnosis and staging of the disease. For tumors extending beyond the mucosa, surgery is followed by intravesical chemotherapy or immunotherapy. High-grade or recurrent tumors are treated with more radical surgery plus intravesical chemotherapy, radiotherapy, or both. Systemic chemotherapy is reserved for clients with distant metastases. Nonsurgical management: Prophylactic immunotherapy with intravesical instillation of bacille Calmette-Guerin (BCG), a compound used to vaccinate against tuberculosis in some countries, is used to prevent tumor recurrence of superficial cancers. This procedure is more effective than single-agent chemotherapy. Mutliagent chemotherapy and radiation therapy are also useful in prolonging life. Surgical Management: The type of surgery for bladder cancer depends on the type and stage of the cancer and the client's general health. Complete bladder removal (cystectomy) with additional removal of surrounding muscle and tissue offers the best chance of a cure for large, invasive bladder cancers. Four alternatives are used after cystectomy: ileal conduit, continent pouch, bladder reconstruction also known as neobladder, and uretersigmoidostomy. Preoperative Care: Coordinate education before the surgery with surgeon and enterostomal therapist. Discuss the type of planned urinary diversion and the......

Cancer

...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 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

...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:......
