A special focus has been laid on the racial and ethnic discrimination among women affected with breast cancer in regards to the surgical treatments being offered in health facilities in the United States of America. Many authors ...

As the name suggests, the paper will be about spinal cord depression. But how come do we call it a depression? The better word should have been spinal cord compression. Any defect in the spinal cord will lead to depression or not can be explained only after the disease has been manifested fully. The paper will discuss only, the condition affecting the spinal cord (Spinal Cord Depression) along with its causes, manifestations, diagnostic tests and treatments.

Etiology

Spinal cord depression occurs due to any injury that results in putting up excessive pressure on the spinal cord. As a result of ...

Cancer diagnosis

Cancer is diagnosed by an expert by critically examining the tissue or the cell samples through a microscope. It can also be done by carrying out tests on cells of the DNA, RNA and proteins (Schwarzenböck et al., 2012). Physical assessment of the patient and family medical history are also essential during diagnosis. Furthermore, a doctor will have to carry out an imaging procedure of some body parts. These imaging procedures can be approached in several ways such as CT scan, nuclear scan, MRI, Ultrasound, X-rays, and PET scan. X-rays uses low doses of radiation to generate pictures ...

Cancer of the cervix develops in the lower parts of the uterus due to the Human Papillomavirus (HPV), transmitted through sexual intercourse. Treatment involves Radiation therapy with chemotherapy or chemotherapy followed by surgery. However, the best treatment plan can be by stage of the disease, for the stage 0(carcinoma in situ) treatment may include laser surgery or conization, internal radiation therapy that best suits those who cannot undergo surgery and hysterectomy for those who no longer want to bear children. Total hysterectomy and conization work for Stage IA1 while radiation therapy and chemotherapy for stage IB and IIA. ...

Over the past few decades, major improvements have been made in the field of cancer treatments, therapies and diagnostics. Cancer nursing is a result of these advances; it continues to play a vital role in offering palliative support to cancer patients and improve their ability to cope up with the disease. Consequentially, cancer nurses have become an integral part of the complex cancer treatment process.
Cancer is a disease characterized by an uncontrollable growth of cancerous cells in the body. These cells are referred to as malignant cells. Although the symptoms of cancer vary depending on the type/location of cancer, in ...

Introduction

Data by the US Institute of Medicine indicates that the number of patients diagnosed with breast cancer yearly stands at an alarming figure of two hundred and fifty thousand. It further shows that breast cancer claims forty thousand lives each year 1. The aforementioned statistics coupled with the fact that current research estimates on the probability of a woman developing breast cancer during the course of her lifetime stand at one out of eight women are the factors that prompted my interest in writing on this particular topic. This paper will therefore focus on the symptoms and treatment of breast ...

Breast cancer is the growth of malignant tissue that starts in breast region and spreads to distant parts of the body. It is most common in women though it can also happen in men to a lower extent. Risk factors are things that heighten the chances of getting cancer (Bunnell, 2000). There are several risk factors for breast cancer, but it is not easy to know how much the factors can contribute. Some of the risk factors for breast cancer include the use of oral contraceptives, dense breast tissue, previous chest radiation, and drinking alcohol among others.
The preventive ...

Introduction

Cancer is a huge problem of all mankind. We know that this is the second disease after cardiovascular diseases in terms of mortality. Currently, a lot of research is conducted to understand the reasons for which there is a cancer, find a cure and to develop methods of prevention. Nevertheless, the problem of cancer has been and remains a priority for the medical community. In developed countries, there is a tendency to reduce the increase in the incidence and mortality from cancer. The main increase in deaths from the disease occurs in developing countries.
There are more than 100 types of cancer that can ...

Introduction

Cancer is an uncontrolled growth or spread of abnormal cells in a human body; it is not a single disease, and it has a group of 200 different diseases . It means that cancers are similar in some ways; however, every type of cancer differs in the way of its growth or how it multiplies. Since cancer is not a single disease, it consists of many different types of cancer that could start in different parts of the body. Cancers differ in types that share one characteristic that is, unchecked growth and progress to a limitless expansion or increase. For example, it could start in ...

Overview

United States has experienced an increase in prevalence and incidence of cancer among its citizens over the last few decades. According to American Cancer Society (2014), cancer refers to a group of diseases that present with uncontrolled growth and spread of abnormal cells. Cancer emerges due to several factors which include; smoking of tobacco, exposure to chemicals and radiation, hormones, and inherited mutations (American Cancer Society, 2014). Even though there are many causes of cancer, the disease can be prevented. For instance, avoiding smoking and minimizing exposure to chemicals and radiation by observing safety precautions can greatly help reduce chances ...

Cancer denotes an abnormal growth of cells, as a result of, changes in gene expressions following deregulated cell division and death (Ruddon, 2007). Consequently, this produces a population of cells that invade tissues and metastasizes to other sites, and if untreated, it causes significant morbidity and/or death of the affected person (Ruddon, 2007). In essence, cancer stems from alterations in the expression of certain genes; this phenomenon deregulates the cellular program for cell division and differentiation. In the long run, cell division, as well as cell death, become unregulated leading to the growth of tumor cells.
The events that trigger ...

Malnutrition is a condition in which the body’s nutritional requirements are not completely met. As a result, there will be loss in body weight, delayed healing of wounds, general weakness and poor resistance to infections. If a patient, who is already hospitalized, is affected by malnutrition, it can worsen his or her condition further and may even lead to death in severe cases. Pregnant women, patients suffering from chronic diseases like cancer, aged people as well as children belong to the highly vulnerable category and malnutrition can cause serious effects in them. In some patients, malnutrition may not be due to ...

Skin cancer is just one of the many types of cancer that affects people and most commonly in the United States. It is a disease whereby cancerous cells are found on the epidermis which is the outer layer of the skin or uncontrolled growth of skin cells. This cancer affects the skin tissues and ...

Cancer is a disease that mostly affects the cells. It is often characterized by out of control cell growth. There are different types of cancer that are grouped by the cells they affect. It is a terminal disease that has no cure but can be controlled and prevented. If cancer is recognized early enough, then the diseases can be controlled from its initial stages before it spreads to the other body parts. Cancer as a disease is very expensive to treat not forgetting it is a terminal illness. Cancer as a disease will affect the body by forming lumps or tumours when the damaged ...
