Introduction

Although drinking tea has been said to have health benefits for many centuries, only recently have its medicinal value been investigated empirically. There are four general categories of tea. These are green, black, white, and oolong tea. Black tea and green tea are the most common types. Black tea, which is obtained after fermentation and oxidation through fermentation, is the most commonly consumed kind. However, recent research indicates that some nutrients and elements are lost through oxidation. Green tea, which is the least unprocessed kind of tea, contains antioxidant polyphenols, especially the catechins believed to contribute to health benefits. Continue reading...

Response

A metaphor implies calling something with a name that belongs to a different thing. The mentality behind what the society normally says about illnesses and people who suffer from them has a negative impact on the sick (Sontag, 100). Most diseases whose causality are not known are awash with symbols There are similarities between the public opinions about cancer, HIV/AIDS and tuberculosis because people associate them with psychological characteristics (Sontag 112).
People create metaphors and symbols with the notion that it will help the patient feel better. These metaphors encourage stigma and make a disease look somewhat like a Continue reading...

Cancer is a term used to define a class of various diseases that entail irregular cell growth resulting in some forms of malignant tumors. When the malignant cells form in one part of the body, they affect the neighboring cells although the diseases can affect tissues far from the place that the cancerous tumor has developed. Recently, cases of cancers have been on the rise, and the reasons behind this could be pollution of the environments, lack of exercises, poor dietary habits, and consumption of carcinogenic substances. Cancer comes in various forms, and if detected early enough most of Continue reading...

Tobacco has a long history in the America since 600 to 900 A.D. It was used predominantly in medical purposes and the people on that time did not smoke every day (Healthliteracy.worlded.org). Today, smoking has become the major problem in the world since 1950s. According to the cross-section data obtained from 187 countries, nowadays there are more than 967 million of people, who smoke every day compared to 721 million in 1980s (BBC.com). It comprises about 1/10 population in the world and there are more than 480,000 deaths per year that are caused by smoking cigarettes in the Continue reading...

A second-generation drug is a drug that is designed to target a patient’s molecules that have defects. These defects may include cancerous cells in the body of a patient. Cancer growth in the human body is the unregulated or uncontrolled growth of cells with metastasis and usually this growth spreads to the other organs and tissues of the body. The second-generation drug targets the cells that are continuously reproducing and thus prevent the cells from continuously reproducing uncontrollably.
The clinical candidate tipifarnib is a second-generation drug that targets the causative agent of the chagas disease. - Protozoan parasite, Continue reading...

Idea # 1: Narrative addressing barriers to colorectal screening

This narrative has been used to intervene in the process of promoting the colorectal screening of cancer disease. Recruitment of participants, whose age ranges between 49 to 60 years has been done to investigate the claims made by renowned researchers, that there is an overestimate of barriers towards cancer screening but the results are not universally satisfactory . I propose that there be a categorical and random allocation of one-half of the recruits to encode the message, the results will be conclude that barriers to screening be predicted to have a minimal barrier in the near future.

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 Continue reading...

Freudenheim, Van den Brandt, Colditz, Goldbohm, Harnack et al. (2005) hypothesized that alcohol consumption increases the risk of lung cancer. Smoking is known widely as the primary cause of cancer of the lungs but a lot remains unknown on the etiology of lung cancer. The study involved a pooled analysis of standardized covariate and exposure data from 7 different prospective studies comprising 3137 lung cancer cases and 399,767 participants. In terms of collection of information, the authors collected information by pooling cohorts, which were arrived at using the criteria of incident lung cancer cases, dietary assessment, a validation Continue reading...

Lung cancer (also called – carcinoma of lungs) is a type of malignant tumor. It emerges from cells paving lungs and bronchi. Usually it takes years for this type of cancer to develop. But if a person gets this type of disease most likely other organs will be affected as well. Lung cancer is a really dangerous for a human, as it is hard to diagnose it and it might be too late to treat it. This disease contributes to the major part of deaths throughout the developed countries. Annually there are about 1 million cases of lung cancer around Continue reading...

Oral cancer mostly affects the mouth, lips and tongue of a person. It affects people across all genders and class in societies. It arises from many factors that boost up its prevalence.

Ultraviolet light (UV) is a largely invisible variant of light which has intense electromagnetic energy and whose wavelength ranges from 0.1 μm to 0.4 μm. Normal visible light varies from 0.4 μm to 0.7 μm. There are, however, levels at which UV light can be visible to some organisms like birds and insects. It is different from visible light because it is of its high concentration; can result in chemical reactions and can harm human beings.
UV light is majorly derived from the sun. In addition there are other particular sources which can be utilized for production of these Continue reading...

Psychology

Question 1
Stanley Schachter's (1964) two-factor theory of emotion can be viewed in part as a social theory of emotion. Explain
The Schachter’s Theory of Emotion integrates the roles of the cognitive factors and psychosocial arousal in the determination of human emotion. It further asserts that the experience specific emotions depends on the cognitive factors exercising over the general psychosocial arousal. These principles coincide with the social theory of emotions, which also asserts that human emotions depend upon psychosocial and cognitive concepts in adults and children consecutively.

Question 2

Upward Social Comparisons refers to comparing ourselves with the people we Continue reading...

In 2012, the USPSTF (United States Preventive Services Task Force) set up new guidelines for the nursing practitioners and other medical officers to follow in practice of cervical cancer screening. The screening helps most women in the early detection and cure of cervical cancer, which may accelerate and cause serious aggregate problems in the future. Women received the new regulations differently with most women interpreting the move to mean reduced frequency of pap smears and delayed first screening for cancer (Plescia, Richardson and Joseph, 2012). However, the implications of the recommendations mean reduced strain for women at average risk Continue reading...

Colorectal cancer is one of the malignant diseases that claim a lot of deaths across the globe. Though causes of cancer are unknown, research believes that there is a strong link between cancer cells and the standards of nutrition (Jun, 2013, p.145). In addition, one’s heritage and lineage contributes to an individual’s risk to developing cancer cells. This means that nutritional factors can prohibit or stimulate the growth of colorectal cancer. Thus, it is evident that dietary habits and heretical genes are the key components in enhancing the colorectal carcinogenesis. It is crucial to not that cancer Continue reading...

Hormone replacement therapy can be simply defined as all the medications that contain female hormones for the replacement of those hormones that a female body does not manufacture after menopause. This therapy is a standard treatment to cure menopause symptoms. Although there are some benefits related with HRT, a majority of doctors are less likely to recommend this therapy as the concerns associated with it are much hazardous (especially for elder women). On the other hand, it could prove as a better option for certain women who have low risk factors (Cabot, 1995).

Risks of Hormone Therapy

At the same time as Hormone Continue reading...

Despite decades of effort and a diversity of treatments, cancer is still a disease with poor prognosis. The cancer stem cell theory substantiates this fact that cancer cells have the ability to influence the growth and spread of tumor. It further states that a cancer stem cell can produce other cancer cells. This is because it withstands death due to its inability to undergo complex mitotic processes. This theory hypothesizes its findings based on tumor growth driven by rare subpopulation of cells. The cancer stem cell theory explains the fundamental force behind cancer by investigating its self renewal and Continue reading...

Breast cancer can be referred to as a cancer type that originates from breast tissue, mostly from the milk ducts’ inner lining or the lobules, which supply the ducts with milk (Sariego, 2010). Cancers arising from ducts are called ductal carcinomas, as those from lobules are called lobular carcinomas. Breast cancer affects humans, as well as other mammals. Breast cancer also affects in men.
Breast cancer occurs due to an environmental factor’s interaction with a host that is genetically susceptible. Normal cells undergo division as many times as required and stop. They get attached to other cells where Continue reading...
