Essay On Ra

Children are more susceptible to changes in their cells if given adult doses of radiation. Primary risks to

From surgery to radium exposure to such extremes as radiation therapy, as doctors’ knowledge of the varying types of cancer, and the expansion of medical research regarding cancer has changed, so has the preferred method of treatment. Doctors and researchers dedicated to studying cancer have led to a greater understanding of cancer development; consequently the development of treatments and cures that are more effective, less harmful, have fewer side effects, and in some cases serve to prevent the spread of cancer.

Radiation therapy is commonly used as a proven and widely accepted way to treat cancer. The American Cancer Society attests to this because of the extensive research they have done in this field. High-energy radiation damages a cell’s deoxyribonucleic acid (DNA). When a cell divides, its DNA splits. According to the Mayo Clinic, radiation therapy is sometimes given with curative intent (that is, with the hope that the treatment will cure cancer, either by eliminating a tumor, preventing cancer recurrence, or by both). In such cases, radiation therapy may be used alone or in combination with surgery, chemotherapy, or all three. Radiation therapy may also be given with palliative intent. Palliative treatments are not intended to cure. Instead, they are meant to relieve certain symptoms and reduce

Cancer is described as the abnormal growth of cells. Normal cells are replaced with abnormal cells in which their deoxyribonucleic acid (DNA) has been damaged or augmented (McCance & Huether, 2014). Cancer cells with their various DNA changes are characterized by growing uncontrollably, being immortal with an unlimited lifespan

Autoimmune diseases materializes when the immune system becomes perplexed and vicious assault the human body, devastating tissue. Thus, both Lupus and RA (Rheumatoid arthritis) are destructive autoimmune diseases. Nevertheless, it is currently undetermined what activates these diseases, but they are regrettably genetic in nature. Both diseases coalesced affect approximately 24.2 million Americans. Though they share similar symptoms, each has its unique way of inflicting excruciating and debilitating discomfort to the human body. This essay will explore the similarities and variances between the two.

Cancer is a genetic, heritable disease in which abnormal cells divide rapidly destroying normal body cells, often being fatal. Cancer can occur in any body tissue; skin, organs, and parts of the reproductive system (Duda). There are various activities linked to different types of cancer, such as smoking, too much sun exposure, gene mutations, carcinogens, and viruses. A major cause of cancer, dating all the way back to the 1950’s, is radiation. Atomic testing ordered by the U.S. Government has been suspected to be the cause of many deaths linked to radiation-related diseases (Williams 149).

Today is my first day in two years not being an RA. Of course there’s a bit of happiness in that; I’ve made it! I gave two years of my life to helping other people and I’m proud of the difference I was able to make and the relationships I was able to build. But also there is a sadness, a longing to rewind.

Cancer is a disease caused by an uncontrolled division of abnormal cells. The DNA sequence in cells can be changed as a result of copying errors during replication. If these changes whatever their cause are left uncorrected, both growing and non-growing somatic cells might gain many mutations that they could no longer function. The relevance of DNA damage and repair to the generation of cancer was obvious when it was recognized that everything that causes cancer also cause a change in the DNA sequence. Tumor suppressor genes are protective genes and normally they limit cell growth by monitoring the speed of cell division, repair mismatched DNA and control when a cell dies. When a tumor suppressor gene is mutated cells grow

Cell recovery: Depending on time, interval, dose and sensitivity of affected cells to radiation, the cells may repair themselves and recover from harm.

Discussion RA is a common autoimmune disease associated with progressive disability, systemic complications, early death, and high socioeconomic costs. RA is characterized by synovial infl ammation and hyperplasia (swelling), autoantibody production (RF and anti-CCP antibody), cartilage and bone destruction (deformity), and systemic features, including cardiovascular, pulmonary, psychological, and skeletal disorders [4]. A number of genetic and environmental factors contribute to disease onset and severity [8] In addition, a number of viral and bacterial pathogens, such as Epstein–Barr virus, parvovirus B19, hepatitis C virus, Proteus mirabilis, and Mycobacterium tuberculosis, may have a role in disease pathogenesis as well [9].Th e

Radiation therapy is the ionization of atoms in tissues resulting in formation of highly reactive radicals in a well-defined, restricted volume (1). In other words, ionizing radiations are used to eradicate tumors and at the same time preserve structure and function of normal tissue. A limitation is prevented from being a problem. If bone marrow or neuronal cells are destroyed or injured, they do not regenerate. However, with radiation therapy, these cells are often saved from injury or destruction, unless the tumor is infecting bone marrow or neuronal cells. Today, radiation therapy is the most popular type of cancer therapy in use. It is used to treat one-half to two-thirds of all cancers, which translates to more than ten percent of the population

This is why BRCA-positive people have a higher risk for cancers. It also explains why they get them earlier in life. They were born already having one mutated BRCA allele ready to fuel cancer cells.

Chemotherapy and radiation are the two most common types of cancer treatments. Chemotherapy is a treatment where cancer patients are given specifically designed drugs that kill cancer cells. Radiation or radiotherapy is a treatment where cancerous tumors are targeted by high-doses of radiation in order to damage the cell’s DNA, causing it to die. While radiation and chemo may be effective on their own, an oncologist may recommend a combination of the two for patients who have an advanced stage cancer. People who have been a patient of cancer, no matter what age, can give the best advice and insight to a topic many know nothing about.

I will also take the opportunity to see how their pre-clinical work in DNA repair assays for the prediction of radiation response and toxicity and the identification and validation of response markers to radiation therapy is used to personalise radiotherapy treatment for patients.

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.
