Medical is a field of knowledge dealing with illness and injury. A person may seek medical care for anything from a sprained wrist to a life-threatening illness, and doctors are the people trained to diagnose and treat those patients. Medical is also a word used to describe the practice of medicine, which involves taking a detailed history of a patient and performing tests to determine the cause of a disease or injury. In the modern world, medical professionals follow a set of standards and guidelines to ensure the safety of patients. This includes following a standard procedure for examinations and diagnostic testing, as well as writing up a written report that is reviewed by the patient’s doctor. In many countries, medical students must write a number of medical essays as part of their course work. Medical essays are usually graded on a scale of A to F, with the highest grades reserved for those that demonstrate advanced knowledge of various medical theories and bodies of knowledge. The discipline of medicine is generally divided into two broad categories: internal medicine and surgery. Both of these fields require a lengthy residency training period after medical school. Internal medicine sub-specialties include pulmonology (the study of the respiratory tract), gastroenterology, endocrinology and hematology. Surgery sub-specialties include orthopedics, ophthalmology, plastic surgery and neurosurgery. Medicine is a highly complex subject, covering a wide range of scientific disciplines. These include cytology (the study of cells), histology (the study of microscopic tissue structures) and microbiology (the study of microorganisms such as bacteria, viruses and fungi). Other important subjects in medicine are epidemiology (the study of the causes, distribution and control of diseases), endocrinology (the study of hormones), pharmacology (the science of drug development) and neurology (the study of the nervous system). Medicine also draws heavily on social sciences and humanities such as philosophy, ethics, history and religion as a basis for its research and practice. As with other subjects of interest on Wikipedia, a good medical article should be relatively dense in inline citations. This helps readers to identify which sources the author relied on and to avoid misquotes or plagiarism. In addition, all medical articles must adhere to Wikipedia’s copyright policies. This is especially important because some topics in medicine are particularly sensitive and can spark strong opinions and debate. These subjects include euphemistic language such as “lost her battle with depression” and controversial topics such as abortion and assisted suicide.

The human body is a complex system, with numerous interlocking parts. The health of an individual depends on the interaction between these different systems, as well as many other environmental and social factors. The definition of health varies widely; it can be viewed as either the absence of disease or medically measured risk factors, or more broadly as a state of physical, mental and social well-being. A number of nations have enshrined the right to health in their constitutions, and the World Health Organization defines health as a ‘state of complete physical, mental and social well-being and not merely the absence of disease or infirmity’. For many people, the term ‘health’ has a broad meaning that encompasses not just the absence of disease, but also an individual’s feelings and behaviour. Various theories of health have been developed throughout history, and each has its own unique set of characteristics and implications for healthcare. A common view of health is that it can be measured objectively, and the medical profession is the sole judge as to whether an individual’s condition meets this standard. However, this approach is problematic for a number of reasons. As medical science advances, individuals who are deemed healthy today may be found to have a disease tomorrow. In addition, the definition of ‘health’ may be biased towards the medical establishment’s judgement of normality, rather than an individual’s own subjective experience. An alternative view is that a person’s level of health is determined by their environment, lifestyle and genetic makeup. This is known as the biopsychosocial model of health, and it recognises that the physical, biological, psychological and social aspects of a person’s life all affect their state of well-being. This model is often used in research and clinical practice, and a variety of interventions have been designed to improve the health of individuals, communities and populations. In modern society, health is a global issue that has become a major focus for governments and international organisations alike. A number of countries have enshrined the right of everyone to quality health care in their constitutions, and the World Health Organisation has established the right to healthcare as one of its primary objectives. Many other nations spend a large portion of their gross domestic product (GDP) on healthcare, as it is recognised as essential to the functioning of any society. Having good health is essential to leading a happy and fulfilling life, but there are many barriers that prevent people from accessing the healthcare they need. These barriers include poverty, illiteracy, inadequate education, lack of employment opportunities and cultural and language differences. Some of these barriers can be addressed by introducing new technology and improving access to healthcare, but others are more intractable. Despite the fact that many healthcare services are now online, there is still a significant gap in information about the health of Australians. This is due to government legislation and policies that have skewed, cancelled or outlawed free market principles from naturally operating within the healthcare ecosystem.

Pharmacy is the science and practice of discovering, producing, preparing, dispensing, and regulating drugs to promote health and well-being. Historically, it was a miscellaneous science that linked the natural and medical sciences, but in the mid-nineteenth century, it became a distinct healthcare profession with its own research and training. Today, pharmacists work in many settings including pharmacies, hospitals, clinics, and private practices. As healthcare professionals, pharmacists play an important role in ensuring that patients receive the right medications at the right time, and are aware of any potential side effects. They can also provide advice on healthy living, and recommend routine screenings at appropriate life stages. Pharmacists work in a wide variety of settings, including community pharmacies, hospital pharmacies, and online pharmacies. They must have an in-depth knowledge of the human body, diseases, and treatment options. They may also be called upon to advise on drug interactions, and they must be able to interpret prescriptions written by doctors. They must also have an excellent understanding of the law and be able to explain complex scientific information in an accessible manner. The pharmacy industry is growing rapidly, and it can be difficult to keep up with all the changes. There are several factors that influence this growth, including increased demand for prescription medication and the rising cost of medical insurance. In addition, the internet is making it easier for people to buy drugs from an online pharmacy. However, there are a number of issues that must be addressed before this industry can become more widely accepted. It is essential that the pharmacist understands how to properly store and preserve medicines, as well as how to safely administer them. It is also the responsibility of the pharmacist to ensure that unneeded or expired medicines are disposed of correctly. In addition, the pharmacist must be able to identify if a patient is receiving duplicate or unnecessary prescriptions. A hospital pharmacist works closely with physicians and nurses in a patient care setting. This can be an exciting and challenging opportunity to gain valuable experience in a healthcare setting. In addition, it is an excellent way to develop your interpersonal skills. It is also a great place to network with other healthcare professionals, which can help you in your future career. The basic five-year curriculum for a pharmacy degree embraces subjects from both the physical and biological sciences, and a thorough grounding in mathematics is required. The profession requires a high level of professionalism, and the practice of pharmacy is heavily regulated. Licensure to practice pharmacy is a requirement in all states in the US, and transferring licensure between states is possible but often involves additional testing or requirements. Pharmacists also need to have a solid understanding of business management and accounting, as they are often responsible for the financial aspect of their practice. This includes purchasing and selling prescriptions, as well as reimbursing healthcare professionals for their services. The use of the mortar and pestle symbol is common in North America.

Cancer is a disease that happens when some of your body’s cells grow and multiply in an uncontrolled way. This leads to a group of abnormal cells that can form a lump (called a tumour) or spread into other parts of your body. Cancer can be caused by many things. It can start in any tissue or organ of the body. It may also start in blood-forming tissues such as bone marrow. Cancer that starts in these tissues is called leukemia. It can also start in nerve cells and spread to the brain, where it causes problems such as headaches and weakness on one side of the body. Cancer can be treated with surgery, radiation, chemotherapy and other medicines. New treatments are being tested all the time. Some of them block the growth of cancer cells and help your immune system to fight them. Others kill or damage the cancer cells. Normal cells grow and divide to make more cells as the body needs them. But sometimes these cells get damaged or become old and die. If too many of these cells build up, they may become a tumor or spread to other parts of the body. Cancer can start almost anywhere in the body, which is made up of trillions of cells. It can be any type of cell — skin cells, nerve cells, muscle cells, bone cells or blood cells. The cause of most cancers isn’t known. But it is thought that changes in genes are partly to blame. Genes contain the instructions that control how your cells grow, divide and die. When these genes get faulty, they can lead to cancer. Cancer can also happen because of something you do or don’t do. For example, smoking increases the chance of getting some types of cancer. Some cancers start in a normal tissue or cell, but the change in the gene makes it more likely to become cancer. Other cancers start in abnormal tissue that hasn’t changed much. For example, a mole that has changes in the way it looks may become a melanoma, a type of skin cancer. In most cases, cancer isn’t contagious. It isn’t caused by germs, like the cold or the flu. But it can be passed on from parent to child through genes. A person who has a family history of cancer may be more likely to have the disease. Other factors that increase a person’s risk of developing cancer are age, genetics and certain environmental exposures such as UV rays from the sun. Cancer isn’t preventable, but there are some ways to lower your risk. For example, you can avoid tobacco smoke and some sun exposure. You can also follow a healthy diet and exercise regularly. And you can get regular checkups to find early signs of cancer. Talk to your doctor about any symptoms you have that worry you. They can recommend tests to find the right treatment for you.

The medical profession deals with human bodies and their ailments, from the physical to the mental. The field includes medicine, surgery, and a variety of other treatments, including diagnostic tests and prescription medicines. It also encompasses a wide range of related topics, such as anatomy, physiology, pathology, and pharmacology. Medical professionals are required to be licensed in most countries, and that requirement typically involves passing a series of exams and meeting other qualifications set by national standards. Because the fields of medicine are so broad and complex, they often have many branches or subfields. For example, a doctor might specialize in anatomical science or biochemistry, while another physician might concentrate on psychiatry or internal medicine. A medical technician might focus on laboratory work or cytology, while a dentist might specialize in dentistry or orthodontics. To understand a medical term, it’s helpful to break it down into its component parts: prefixes, roots, and suffixes. For example, the word “spondylolysis” is formed from spondylo, which means vertebra, and lysis, which means dissolution; it refers to the breaking down of a bone in the back. Another example of a medical word formed from its components is the anatomical system “skin” — it’s created from the root words integument, which means covering, and skin. Most doctors and other medical professionals keep abreast of the latest research in their fields by reading medical journals. These scientific publications usually include studies and articles on the causes and treatment of diseases, disorders, injuries, or other bodily ailments. Medical journals are generally subscription-based, with doctors and other scientists who contribute to the journal receiving payment in return for their studies and articles. However, the National Library of Medicine’s database called PubMed allows nonsubscribers to read medical articles online. Medical science is a broad discipline that covers many areas of study and research, such as anatomy, chemistry, biology, physics, and mathematics. It includes a number of other subfields such as biomechanics, which uses physics to model and study biological systems; pharmacology, the science of medications; and forensic medicine, which investigates the cause and manner of a person’s death. While some people have a natural ability to learn medical terms, others find it very difficult and frustrating. To help make it easier for those unfamiliar with the terminology, there are many resources available. In addition to online courses, books and other study guides can provide an overview of medical vocabulary and explain how it is used. It’s also helpful to practice by making flashcards and learning the terms as you hear them. This will help you retain the information and apply it to your work. Also, familiarity will go a long way; as you use medical terms more frequently, they’ll begin to feel like second nature.

The World Health Organisation defines health as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” It is important to note that unlike disease, which can be categorized, defined and even understood by scientific means, the concept of health is much more complex. Health is subjective and highly personal, with a wide range of interpretations. Individuals view health from different perspectives, and their perspective influences the way they behave with respect to healthy habits and lifestyle choices. The health of peoples is fundamental to their overall well-being and the enjoyment of life. It is a fundamental human right, which governments have the responsibility to promote and protect. Health includes the individual’s ability to function in their prevailing environment and to adapt to changes therein. It requires a combination of a balanced diet, proper exercise, rest and sleep, and the support of family and friends. It also requires access to medical and psychological care, as well as the education of peoples in health matters. People’s health depends on the circumstances in which they grow, live, work, play and age, including their socioeconomic position. These factors influence the development of health behaviours and interact to cause or prevent diseases, such as cancer and diabetes. They also contribute to health inequities – avoidable differences in health status seen within and between groups and countries (Commission on Social Determinants of Health 2008). A person’s health is dependent upon the quality and quantity of food they eat, their lifestyle and activity levels, their level of stress and their genetic makeup. They can also be affected by environmental factors such as air and water quality, housing and community design, and the presence of natural environments that provide recreation and leisure activities. Generally, it is believed that people have the ability to maintain their health and fitness through positive lifestyle choices. These include eating a nutritious diet, getting enough physical activity, avoiding tobacco and excessive alcohol use, and sleeping for a reasonable amount of time each night. The environment is considered to have a direct impact on a person’s health, as it influences the development of diseases and conditions, such as obesity and depression. Considering the complexity of health, it is no wonder that there are many definitions of the term. It is important for health professionals to understand the varying definitions of health, so that they can tailor their messages accordingly to ensure that people are able to follow the advice that is most appropriate for them. The most common definition of health is that it is a state of being free from disease and infirmity. However, this definition is limiting, as it does not take into account the fact that a disease or infirmity can be present in an individual without them being able to recognise it or understand its causes. A second definition is that of health as a positive concept, which is broader in scope and encompasses both the presence and absence of disease and infirmity.

Pharmacy is the science and practice of discovering, producing, preparing, dispensing, reviewing, and monitoring medications, aiming to ensure the safe and effective use of medicines. It is a diverse science that links health sciences with pharmaceutical sciences and natural sciences. It also encompasses pharmacy education and professional advocacy. The model aims to reduce the ambiguity that is often associated with the labeling of the discipline, and it is expected to provide a platform for dialogue in moving toward consistency and rationalization of terminology in the pharmacy sector locally, nationally and internationally. Historically, the professions of pharmacy and medicine were distinct. Physicians performed the diagnosis of illnesses and prescribed treatment, while pharmacists formulated, prepared and dispensed medicines. This arrangement was encouraged by ancient Greek and Roman medicine, as well as the medieval world, and Benjamin Franklin, the founder of America’s first pharmacy, took a strong stand in keeping physicians and pharmacists separate. Today, the responsibilities of pharmacists are broad and varied. They collect and review patient histories and drug use data. They help patients select over-the-counter and herbal products, and they educate people on the proper use of these medicines. Pharmacists also perform compounding, a process of creating custom drugs. For example, if a manufacturer only provides a medication in tablet form, a compounding pharmacist could prepare it as a medicated lollipop for a patient who cannot swallow tablets. The most important task of any pharmacist is to protect patient safety. This involves ensuring that the drugs are properly labeled, and that the dosages and frequency of administration are correct for each patient. They must also identify potential contraindications, which are situations in which a drug should not be used because it would harm the patient. For instance, a person with a bleeding disorder should not take aspirin because it could lead to excess blood loss. Finally, pharmacies must comply with all relevant state and federal laws and regulations. In addition to their clinical and administrative duties, pharmacists provide counseling services to patients and medical staff. They advise them on the use of medications and recommend appropriate lifestyle changes, such as smoking cessation programs or weight loss plans. They also educate patients on drug interaction warnings and side effects. Moreover, they offer medication adherence programs, such as the Million Hearts Initiative, which encourages patients to regularly monitor and record their blood pressure readings. In order to become a pharmacist, you must complete a bachelor’s degree in pharmacy science and pass the North American Pharmacist Licensure Examination (NAPLEX) and the Multistate Pharmacy Jurisprudence Examination (MPJE). Most states also require a background check and fingerprinting. Once you have received your license, you may work at a hospital, private pharmacy or health clinic. You may also choose to open your own independent pharmacy. In addition to selling prescription drugs, some independent pharmacists also offer immunizations and healthcare consulting services. Some offer online consultations through webcam or telephone. They are also known as virtual or mail-order pharmacies.

Cancer is a disease that occurs when abnormal cells grow and divide without control, forming tumors and disrupting normal tissue functions. Cancer can spread to other parts of the body through the blood or lymph system in a process called metastasis. Cancer is one of the leading causes of death in the world, but research and treatment advances are helping to reduce the number of deaths from the disease. A cancer diagnosis can be frightening, but it is important to remember that you are not alone. Your healthcare providers are here for you every step of the way to help you navigate your cancer journey. While no two cancers are the same, all cancers start when some cells in the body become abnormal and start to grow and divide out of control. Cells are the basic building blocks of the body that make up tissues and organs. Under normal circumstances, when a cell needs to grow or repair itself, it gets instructions from its DNA. These instructions are translated into the proteins that cells need to do their jobs. But when the genes that control this process are damaged or mutated, the instructions get distorted and the cell develops into a precancerous or cancerous cell. Cancers can form in almost any part of the body and they can affect all the body’s tissues and organs. The development of a cancer is not instantaneous; it takes time for the mutations to accumulate and lead to the uncontrolled growth of cells that forms a tumor. The genetic changes that cause cancer are usually inherited but can also happen when errors occur during cell division. They can be caused by certain environmental factors, such as radiation or chemicals, that damage cells or can be passed from parent to child during pregnancy. Most often, however, these mutations develop slowly over a person’s lifetime and increase the chance of developing cancer later in life. These genetic changes can lead to different types of cancers, and they typically affect three main groups of genes: proto-oncogenes, tumor suppressor genes, and DNA repair genes. Together, these gene mutations allow cancer cells to grow and divide more rapidly than normal cells, and they can ignore signals that normally tell them to stop dividing or to die (a process known as programmed cell death, or apoptosis). In addition, some types of cancer cells are able to break away from the original tumor and travel to other parts of the body through the blood and lymph system, where they exit the vessels and form new tumors. In these cases, the cancer is considered to be metastatic. It’s estimated that between 30 and 50% of all cancers could be prevented by avoiding risk factors, getting regular screenings, and practicing healthy habits, such as eating a nutritious diet, maintaining a healthy weight, and staying physically active. The most common cancers — like colorectal and breast cancer — are often preventable by screening for them regularly.
