Cancer refers to a condition characterized by the abnormal growth of cells in some parts of the body. Such cells reproduce uncontrollably leading to the development of tumors that can infect other body parts in a process known as metastasis. It is urgent to note that some tumors are not dangerous. Thus, it is important for medical doctors to diagnose tumors with highest accuracy to avoid potential confusion. Cancer can occur in more than two hundred forms (Schmidt & Popham, 1981). Each cancer is

Cancer is a disease caused by the abnormal cells in a part of the body. Cancer can start anywhere in the human body. Normal human cells grow and divide and form new cells when the body needs them. When normal cells become old or when they are damaged new cells take their place. When cancer develops that process is starts to break down. Cells become more abnormal and the old cells or damaged will stay and new cells will not form when needed which may cause a tumor. Many cancers form tumors but cancer

Pertussis, also known as whooping cough, is a disease involving the respiratory tract. It is a highly contagious bacterial disease that causes coughing uncontrollably and violently. The constant cough makes it harder to breathe, which could lead to apnea. A “whooping” sound is often heard after a cough because the patient will need to take a breath. Pertussis is caused by a bacterium named Bordetella Pertussis. The bacteria attaches to the cilia that lines the upper respiratory tract and releases

Although most of us are left to wonder, some people have horrendous, incurable, life-changing diseases that makes them get closer to their finish line. This group of people should be entitled to know when their day will, thus they should be informed by their doctor. Lives could end in a blink of an eye; therefore, we live life to the fullest. On the contrary, humans with life threatening diseases don’t have the option to wait longer for a beautiful experience, so they should take advantage

Robert Cook discuss the increasing problem of cross-species diseases and their spread throughout the world, citing a breach in the “Darwinian divide” that has kept epidemics at bay (1). While previously, only a few diseases could affect both humans and animals, in recent years the increase of globalism and introduction of species into new environments have contributed to this global problem. Over half of the 1,415 categorized infectious diseases are known to infect both animals and humans, which presents

effect on human society. Transport and population density around the world are not the sole factors leading to the enhancement of diseases spreading around the world. Other than human to human transmission of infectious diseases, a large number of viruses and bacteria originate from parasites. Climate change has shown to be a considerably major factor in affecting diseases as variations of humidity and temperature changes how active parasites are in certain areas (Obenauer et al. 2017). The Aedes aegypti

plants, and animals. Because many microbes reproduce rapidly and require minimal resources for survival, they are a potential danger in a wide variety of occupational settings. Some examples of biological or infectious agents include anthrax, botulism, Ebola, blood borne, and food borne pathogens. When exposed to biological or infectious agents humans may present with immediate and long term effects. Immediate effects are the initial signs and symptoms that are manifested once the subject comes in contact

Ebola in Liberia, Sierra Leone and Guinea, an increase of new HIV infections and a rise of various diseases caused by war and radioactive contamination are just some of the problems we face today. A very brief look at our daily news is enough to show the desperate need for global health solutions. The simple observation is: diseases do not stop at a country's border. Therefore the global health policy designated to fight them should not do so neither. What is needed are aspiring health policy makers
