Chemotherapy Kills Cancerous Cells

Targeted therapy, which first became available in the late 1990s, has had a significant impact on the treatment of cancer. Currently, because of advancement in the field of technology, various types of therapies are discovered to treat cancer. In this essay, targeted therapy is defined as a therapy in which various drugs or other substances are used to recognize and kill the cancerous cells without harming the normal cell (National cancer institute, 2014). Effectiveness refers to the degree in

For years people have been looking for a cure for the devastating disease of cancer. Cancer is the third highest killer in the US with over 2,500,000 victims per year. Oncologists and scientists around the country are researching all forms of cancer in an effort to understand, treat, and ultimately defeat this disease. Already there have been numerous advances in the field, such as chemotherapy and gene therapy. One advance has been the use of a cell process known as apoptosis. By harnessing this normal cell process, scientists hope to have found an effective way to combat cancer.

Over the last decade, medicine has acknowledged the psychosocial impact of cancer treatments on patients, to the point that it has become a subject of psycho-medical research. Chemotherapy-induced alopecia (CIA) is a physical condition that can have profound psychosocial consequences, leading to a negative body image, lowered self-esteem, and a reduced sense of well-being. Patients, women who fear alopecia in particular, may sometimes refuse or select another treatment that lower the risk of baldness. In her testimony, Lori, a breast cancer patient, expresses a common feeling for women with cancer: “The worst part of this entire experience [cancer], is losing my hair [….] The chemotherapy would be so much easier if I had my own hair. I appreciate

    Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.

“The very success of his esoteric therapeutics too often leads the physician to believe he can do what is beyond his doing and save those who, left to their own unhindered judgement, would choose not to be subjected to his saving.” (Nuland 1993 221) I was bothered by reading this quote because it makes an issue arise. I will describe this issue and how I relate to it.

A 45 year old male, with a history of smoking ½ packs of cigarettes a day for the past 30 years has been diagnosed with laryngeal cancer. The patient comes into the hospital for a follow up visit to his health care provider. Where he has been getting radiation and chemotherapy treatments for the cancer. He has complaints of pain, dyspnea at times and dysphasia. While discussing the progress of his condition the doctor states that the chemo and radiation therapy has not been successful and the cancer has started to progress. The doctor then states the next steps to prevent the spread of the cancer, and that’s to have total laryngectomy surgery. The patient understands the severity of his condition but is now experiencing anxiety because of

There are many different types of illnesses and diseases that are culprits for taking the lives of people worldwide. Of the different diseases, cancer is one of the most frequent causes of death. Cancer is defined as unregulated growth of cells that deviate from usual cellular activities. This includes the development of tumors and eventually the invasion of other tissues. There are different stages of cancer (0-4) that mark its progression. Depending on the state of the tumor, the types of treatments will vary, which determines its curability as well. During the initial stage (0), it is a state where the tumor cells are localized in one area and remain static. At this stage of cancer, the

Bacteria accurately target tumors, actively enter tissue, simply recognized and controllably produce cytotoxicity. also, Several popular cures such as chemotherapy and radiation are poisonous for healthy tissue and not fully damage every cancer cells. Three main reasons for these difficulties are deficient tumor targeting, poor tissue invasion and insufficient toxicity to each cancer cells. These disadvantages limit qualified therapy and are linked with the rise in morbidity and mortality.

Cancer is one of the leading causes of death worldwide as it can develop in almost any organ or tissue. Significant advances in understanding the cellular basis of cancer and the underlying biological mechanisms of tumour has been vastly improved in the recent years (Jiang et al. 1994). Cancer is a genetic disease which requires a series of mutation during mitosis to develop, its characteristics can be associated with their ability to grow and divide abnormal cells uncontrollable while in the mean time invade and cause nearby blood vessels to serve its need. Even though many people are affected by cancer today, the abilities which cancer cells have make it hard to find a single effective treatment for cancer. The focus of research now lies

Since the discovery of the mysterious disease; cancer, oncologists and physicians are keen on finding a cure for it or at least minimize the risk of it. Treatment methods have evolve over time. One of the effective yet hazardous methods in treatment lately for cancer is by the use of radiation. Radiation therapy is an ionizing radiation that uses gamma rays in high-energy to shrink and destroy the suffering cells. In specific, it targets these irregular cells and cause harm either to the DNA straight away or by creating free radicals, which in turn damages the DNA of cells and cause them to stop growing and die.

When we hear the words, cancer treatment, our minds naturally shoot straight to chemotherapy. Chemotherapy is one of the most commonly used ways to treat cancer. Chemotherapy did not have original plans to treat cancer patients but it did have other plausible problems to aid. After WWII, lymphoma, a form of chemotherapy, was used to help soldiers who were harmed by mustard gas (Chemo Brain, 2012). This medical advancement continued to progress into what we now know as chemotherapy. However, no action takes precedence without effects, good or bad. Although chemotherapy is given to cancer patients in hopes of a positive outcome, chemo can have negative effects. Common effects that are seen in cancer

Cancer is a challenging and fatal disease which can strike at any minute. The typical treatment for the illness includes radiation and chemotherapy, however both treatments have terrible side-effects which are frequently the primary cause of death in cancer patients. Thankfully, the illness has been dealt with naturally for centuries, so there are many alternative treatments that can assist.

Chemotherapy is a drug, or a variety of different drugs designed to kills cancer cells that have metastasized around the body, shrink primary tumours or slow the growth of tumours (Triggle & Hecht, 2010). It is a non-selective cytotoxic drug which target both malignant and normal cells (Craft, Gordon & Tiziani, 2011). Radiation and surgery are also treatments, used with chemotherapy to destroy cancer cells in the body (Sugerman, 2013). Chemotherapy is done to shrink a tumour before surgically removing it, or may even be done after surgery to destroy any cancer cells that are left behind (Sugerman, 2013). Nonchemotherapy agents are sometimes administered with chemotherapy, such as antibodies, to help reduce tumour growth (Sugerman, 2013).

Incurable and slowly deteriorating billions of bodies worldwide, Cancer is one of the biggest killers in the world. Sometimes going undetected, Cancer causes cells to divide uncontrollably and if gone undetected or if treatment fails, is extremely deadly to both humans and animals. Cancer can be located almost anywhere in the body and is able to spread everywhere if uncontained. The treatments most often used to treat Cancer are chemotherapy and radiation. Chemotherapy is a treatment that uses different medication and chemicals, inserted through I.V and pills, to rid of any Cancer in the body. Radiation is the use of radiation to target and obliterate cancer cells. Radiation can be done externally by machine or internally through the use

In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earliest beginnings coming from the discovery of x-rays in 1895 by Wilhelm Röntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective. Radiation therapy is a curative treatment approach for cancer because it is successful in killing cancerous tumor cells and stop them from regenerating.
