Health, the state of being free from disease and infirmity, is an important concept for understanding human well-being. It is an essential ingredient in determining how we should live our lives and how society can best support people’s ability to function. Health is a multidimensional construct that reflects the individual’s overall functioning, defined as physical, social and mental well-being. It includes a person’s abilities, resilience and quality of life, allowing them to meet the challenges of a changing environment. It also requires the active participation of people whose health is to be promoted. For many years, the international community was largely focused on defining diseases and the prevention of their spread. But the need to move beyond disease-focused definitions of health has become increasingly apparent. The definition of health in the 1948 World Health Organization Charter was a milestone, recognizing that well-being is distinct from and not synonymous with the absence of disease or infirmity. This more expansive definition of health has broad implications for research, policies and practice, particularly as it relates to disability and chronic conditions. A number of ways of thinking about health have been proposed. A common view, which is influenced by the medical profession and the philosophy of humanism, equates health with the freedom from symptoms, signs and abnormalities of any kind. This approach has the advantage of clarity and simplicity; it is straightforward to understand and communicate. However, it fails to acknowledge that individuals can feel ill even when no disease is present and that they may respond differently to their disease or its treatment. Some of the most influential ideas about health were introduced through a broader perspective. The social and environmental movement of the early 20th century emphasized the influence of an individual’s surroundings on health. This idea was later expanded into a more holistic conception of health in the 1980s by fostering the development of the health promotion movement. This led to a third way of thinking about health: a dynamic concept that involves the capacity of people to adapt to change. While it is true that some determinants of health are directly measurable and amenable to intervention (such as mortality and disease incidence), it has been more difficult to identify or measure the many indirect forces that impact health. A broader definition of health, as described in the field model framework, encourages community-level efforts to consider a wider array of targets than just specific behaviors or disease measures. For example, if a community is seeking to improve the health of its adolescents, efforts might include reducing their feelings of alienation and hopelessness through the use of after-school programs and athletics at night, family preservation and improved church-based communities. These targets are not easily captured by traditional biologic and epidemiologic measurements, but they are essential for reducing unintended pregnancies, substance abuse and other forms of dysfunction in the community.

Pharmacy is a health science that integrates the principles of medicine, biology, and chemistry with the development, production, preparation, dispensing, and monitoring of drug therapy. It is an essential component of contemporary healthcare and the overall health care system. The practice of pharmacy is a highly complex and scientific discipline that involves analyzing and responding to individual patient needs. It requires a deep understanding of the pharmacology of medicines, the delivery characteristics of dosage formulations, and the physiologic and pharmacologic outcomes of drug interactions with individuals and the societal systems in which they are used. Pharmacy focuses on the safe, effective, and affordable use of medications. The practice of pharmacy also includes educating patients and healthcare professionals about medications, disease states, and proper medication usage. Pharmacy professionals are also trained in administering vaccines and providing health maintenance services such as flu shots, cholesterol screenings, blood pressure monitoring, and smoking cessation programs. In addition, pharmacists are trained to make prescription drug recommendations and to monitor drug effectiveness and side effects. In addition, a pharmacist can perform other important health-related tasks such as taking and testing blood for certain illnesses and diseases, administering immunizations without the need for an appointment, and counseling patients on healthy lifestyle choices including diet, exercise, stress management, and healthy sleep habits. Pharmacy is a very rewarding career that offers opportunities to work in many different settings. Those interested in pharmacy should be aware that the profession is highly regulated. Pharmaceutical Research Pharmacists with a PharmD or MS in pharmaceutical sciences are uniquely qualified to make advancements in medicine through discovery-based research. This is an exciting field that allows you to be involved in the development of new therapeutic approaches and treatment methodologies to treat diseases and conditions. This type of research can be found in both academic and industry settings, and the work is challenging, rewarding, and exciting. Pharmacy is a unique and highly specialized field that involves a variety of disciplines, such as business management, team leadership, financial planning, and efficient operation of a pharmacy. The skills learned in this field are highly transferable and can be leveraged across industries. Aside from the technical aspects of the profession, the interpersonal relationships built by working as a pharmacist are invaluable. The high-touch activities that pharmacists perform, such as one-on-one medication support and behavior coaching, can make the difference between patients adhering to their prescriptions or not.

Cancer is an illness that develops when cells in your body start to grow and divide abnormally. The resulting mass of cells is called a tumour. Cancer can start in any part of the body and it can spread to other parts if it isn’t treated. Some types of cancer are easier to treat than others. But all cancers can cause serious health problems. The earlier cancer is found, the easier it is to treat. That’s why it’s important to know the warning signs of cancer. Cancer can develop slowly and may not show any symptoms for a long time. This is known as a latency period. This is why it’s important to go to the doctor if you think you have cancer or are at risk for getting it. Most cancers are caused by things you can’t control, like your age or genes. But some cancers can be prevented by quitting smoking, eating more healthy foods, staying physically active and avoiding too much sun exposure. The American Cancer Society recommends that you discuss your risk factors with your doctor. Scientists have learned that cancer is a process of evolution that starts when normal cells begin to divide uncontrollably and don’t die when they should. Over time, mutations accumulate in the genome of these cells. Mutations may cause a gene to stop working properly, causing the cell to keep growing and dividing when it shouldn’t. The mutations also change the way the cell looks and makes it more likely to form a tumor. Unlike normal cells, which are homeostatically maintained at densities that leave them with sufficient access to resources, reasonable crowding and limited exposure to toxic metabolites, cancer cells proliferate without any controls. As a result, they pack into tissues at higher densities than normal cells. When cancer cells clump together, they form a lump of tissue (a tumor). The first time scientists saw evidence of cancer was when they examined an abnormal mole that looked different from a regular one. They called this a malignant tumor and considered it to be fatal (2, 3). At this early stage of understanding cancer, the words “malignant” and “tumor” were used interchangeably. Later, people began to distinguish between benign tumors and malignant ones. Benign tumors can be removed surgically. Cancers that spread to other parts of the body are more dangerous and should be treated as malignant. Treatment for cancer can include surgery, chemotherapy, radiation therapy and hormone therapy. Radiation therapy uses high-energy rays, such as X-rays or proton beams, to kill cancer cells. Hormone therapy stops cancer cells from getting the hormones they need to grow. Some patients receive bone marrow transplants to replace the bone marrow cells damaged by very high doses of chemotherapy and radiation.

The field of medicine covers many aspects of health and wellness, from diagnosis and treatment to medical research. Traditional modern medicine includes surgery, drugs and other therapies such as acupuncture and art therapy. Alternative or complementary medicines include herbal remedies and some forms of naturopathy. A doctor is a person who has been trained in the art and science of assessing, treating and preventing disease using knowledge gained from training, experience and clinical judgment. A clinician is a health worker who interacts directly with patients, such as nurses, doctors and psychotherapists. A physician may be a GP, an internist, an oncologist or a surgeon. A health care system is the organization that provides health services to a population. Health care systems are influenced by social and cultural factors, economic conditions and health policies. Access to healthcare depends on an individual’s ability to afford it and their level of health literacy. The provision of healthcare services is dependent on the availability of money, personnel and infrastructure, all of which are often limited by budget constraints, sociocultural expectations and personal limitations. Medical research is the study of biology and its application to the development of new drugs, treatments and cures. This involves a wide range of scientific disciplines such as chemistry, biology, physics and pharmacology. The aim is to improve and extend the life of humans and animals through the prevention or treatment of diseases and their consequences, such as disability and death. Some examples of medical expenses are eyeglasses, contact lenses, a hearing aid and dental work. The amount paid for a program to help you stop smoking is also considered a medical expense. However, you can’t deduct any expenses for a controlled substance that isn’t prescribed, such as marijuana or laetrile, even if it’s legal under state law. You can usually deduct the cost of a wheelchair or other assistive device for yourself, your spouse or your dependents. You can also include in medical expenses the cost of modifying your home to make it accessible to someone with a physical disability. This might include adding handrails in the bathroom or grading the driveway to allow you to use a motorized scooter. However, you can’t deduct the cost of a home improvement made for a personal motive, such as making a room more attractive or convenient. If you sell medical equipment or property that you deducted in an earlier year, use Worksheet D to figure your adjusted basis. You use this number to determine how much of your reimbursement is taxable. You must report any reimbursement you receive in a later year that wasn’t included in your 7.5% or 10% AGI limit for figuring your medical deduction. See Reimbursements in Pub. 525, Taxable and Nontaxable Income, for more information. You must also report on your return any amounts you received in a later year that were previously deducted as medical expenses. However, this doesn’t apply to amounts reimbursed by a flexible spending account or workers’ compensation insurance.

Generally, health is thought of as being the absence of disease or injury. However, a lot more goes into being healthy than that. The five dimensions of health are physical, emotional, social, spiritual and mental. How we define Health will have a significant impact on the types of goals we set for improving it. For example, if it is simply defined as the absence of disease, this would lead us to think that our primary goal should be to remove diseases from society. By contrast, if we define Health more broadly as including the capacity of individuals to function and participate in society, then our primary goal becomes one of increasing capacities rather than eliminating diseases. Another way in which the definition of Health affects the goals we set is by how it influences our understanding of what causes differences between people’s health. For example, if the primary feature of health is that it is the capacity to function in the face of adversity, then this tends to view health as a matter of behaviour, such as adherence to treatment regimens, rather than as a wider concept of social and environmental factors that may impact health, such as living conditions or genetic endowment (Department of Health 2022). A final consideration is how we define Health in terms of its value to the individual. This is particularly important as the committee definition, which focuses on functioning, places emphasis on the importance of an individual’s experience of disease or injury; their responses to their illness and its management; their functional ability in work, family, and community; and their sense of well being in many spheres. The committee definition also allows improvement efforts to focus on those aspects of the environment and lifestyle that we know have a direct impact on health, such as living in areas with good quality medical care or the avoidance of smoking. It also accepts that there are some aspects of health that we cannot measure but are important for improving people’s health, such as the effects of poverty or low social class on mental health. Finally, when we are deciding how to write about Health, it is helpful to consider our audience. This will influence what we write about, and in which format. For example, writing for a general news website is different to writing for a women’s health or parenting magazine. By thinking about our audiences, we can make sure that our articles are relevant and appropriate. This will increase the chances that they are read and understood. Then we can achieve our objectives of educating and informing the public.

The pharmacy, a vital part of the healthcare industry, is where patients can receive advice and information about their medications. Pharmacists can help them manage their conditions, and provide them with vaccines to prevent illness. A pharmacist can also advise on diet, exercise and other lifestyle changes that will improve overall health. A pharmacist has a unique role in providing outcomes-oriented care that ensures effective drug therapy, while minimizing adverse events and economic burdens to the patient. To achieve this goal, a pharmacist must carefully review subjective and objective data in regard to the patient’s underlying health, diet, exercise, medication history, present illness and other medical conditions. The pharmacist must also evaluate the pharmacokinetics of the selected medication, its side effects and contraindications. Pharmacy has evolved from a purely transactional role to a more clinical practice setting. Many pharmacy professionals now work directly with physicians in hospital clinics, physician offices and specialty care settings (e.g., oncology centers). Pharmacists can also be found in ambulatory care and long-term care facilities, as well as the public sector and the military. Today, there is a much greater selection of prescription and over-the-counter medications available than in the past. With the ever-increasing number of medications, it is imperative that prescribers and patients work closely with pharmacists to select the most appropriate medication to treat a particular disease or condition. This will improve adherence to the medication regimen and enhance the patient’s outcome, while decreasing cost and complications. Pharmacists are trained to administer vaccinations, which can prevent diseases such as the flu and shingles. They are also qualified to perform basic health screenings, such as measuring blood pressure and heart rate, testing glucose levels and assessing cholesterol levels. In addition, they are able to assist with other health related issues such as smoking cessation programs and diabetes management. One of the most important things that a pharmacist can do is to help people dispose of unwanted or expired medicines. This is important because unused or expired medicine can fall into the wrong hands and harm a person, so taking them to the pharmacy is an excellent way to get rid of them. Pharmacists are also highly trained in preparing drugs in new dosage forms. This is called compounding and it can be used for patients who have specific allergies or can’t take certain types of medications as a pill. For example, if a patient has trouble swallowing pills, a compounding pharmacist can make them into a medicated lollipop. They can even prepare custom-made creams and ointments for various ailments.

Cancer is a disease that starts when some of your body’s cells start to grow and multiply out of control. There are many different types of cancer and each type can grow in different parts of the body. Cancer can cause symptoms like a lump or bump, pain, or changes in your skin or eyes. There are different treatments for each type of cancer. They may include surgery, radiation therapy, or chemotherapy. Your doctor may also suggest that you join a clinical trial. A clinical trial is a way to test new treatment or diagnosis methods. The word “cancer” comes from the Latin word for malignant, meaning that it spreads quickly and is hard to treat. There are four stages of cancer, and each stage describes how far the cancer has spread. All cancers are diseases that begin in cells, which are the basic building blocks of tissues and organs. Every day, billions of cells in your body are dying and being replaced by new ones. This process usually happens without any problems, but if some of these cells are damaged or wrongly programmed, they can begin to multiply out of control. The cells that form cancer can grow into a mass of tissue called a tumor. They can also break away and travel through your blood or lymph system to grow in other parts of the body. This is called metastasis. There are over 100 different types of cancer. Each type has a different name and affects a different part of the body. But all cancers have one thing in common: They are abnormal. There are many possible causes of cancer, including your lifestyle habits, genes you get from your parents, and being exposed to certain things in the environment. Cells that develop into cancer ignore signals that normally tell cells to stop dividing or to die (a process known as programmed cell death or apoptosis). They also ignore signals that keep cells from growing too fast, and they can even grow into areas where they aren’t needed. They can also hide from your immune system, which normally eliminates damaged or abnormal cells. To cure your cancer, your healthcare team will give you chemotherapy or other drugs that kill cancer cells. These drugs may make you feel sick, such as having nausea and vomiting. They may also damage your heart and lungs. The drugs are given at regular intervals, usually over a few weeks, with rest periods in between. Some cancer patients can benefit from other types of treatments, such as biologic therapies or stem cell transplants. These treatments use your own healthy stem cells to replace the cancerous ones.

Medical is the branch of science and knowledge devoted to the maintenance of human health by the diagnosis, treatment and prevention of disease. It is a multidisciplinary field that includes research in biology (e.g. in cellular systems and animal models), chemistry, physics and pharmacology, together with the application of these disciplines to medicine. Medicine is also concerned with the history of medicine, its foundations in philosophy and religion, and the cultural context of healing. Modern medicine is practised by specialist physicians and a wide range of other highly-trained health care professionals. These include nurses, emergency medical technicians and paramedics, laboratory scientists, pharmacists, physiotherapists, occupational therapists, speech therapists, dietitians, biomedical engineers and radiographers. Physicians are trained in “evidence based” or western medicine, which combines ancient Hippocratic principles with scientific research. The latter may involve preclinical research in cellular systems and animal models, or clinical trials on patients. Medical researchers are also often interested in ‘big picture’ issues such as public health, epidemiology and bioethics. A major shift in medical thinking occurred after the Black Death of the fourteenth and fifteenth centuries, when physicians began to reject the notion that just because an ancient philosopher or physician said something was true meant that it must be so. This led to a gradual rejection of the ‘authority approach’ to medicine, and the development of a’scientific method’ for understanding and treating illness. The discipline of medical anthropology is concerned with the study of the cultures and societies that produce, use and consume medical knowledge. This field of study has become increasingly important as the world becomes more global and interconnected. Medicine is a complex mixture of art and science. Its history spans thousands of years, beginning with the application of herbs and prayer for healing, through to modern pharmaceuticals and surgical techniques. It is an art of applied science, with a strong basis in empirical evidence and a deep respect for the human body. It is also a discipline of continuous learning, as new discoveries in biology, physics, chemistry and mathematics inform the practice of medicine. The scientific disciplines which underpin medical practice include anatomy, cytology, histology and biochemistry. Anatomy deals with the structure of organisms, whereas cytology and histology focus on microscopic structures and biochemistry is the study of the chemical processes occurring in living cells. Medicine also applies the laws of physics and chemistry to biological fields, for example in aeromedicine which examines problems related to flying and space travel, or in toxicology which studies the effects of chemicals on living organisms. The practice of medicine is regulated in most countries by law to ensure that practitioners are competent and ethical. This is designed to protect patients from charlatans who may misuse the medical profession, and to encourage the spread of knowledge. It is a very large and diverse field, with many subfields. Each of these have a unique set of terms that are specific to them. This is reflected in the number of suffixes that appear at the end of medical words: for example, phlebotomy means blood-taking; gastroenterology means the stomach; ophthalmology concerns the eyes; and radiology refers to imaging.
