Cancer is a disease that starts in cells. Cells are the basic building blocks of our bodies and make up tissues and organs. Cancer forms when cells grow out of control and spread into surrounding tissue. This process is called metastasis. Cancer can affect almost any part of the body. There are more than 100 types of cancer and each type has its own set of signs and symptoms. All cancers start when some cells become abnormal and start growing out of control. Most cancers start in the skin or in blood vessels but can form in any cell in the body. Some cancers are more likely to form in specific parts of the body, like the lungs or bowel. The five most common cancers are lung, breast, prostate, bladder and colorectal. There are many reasons why normal cells may change and develop into cancer. Some of these changes are caused by things we can avoid, such as smoking or overexposure to sunlight. Other causes are related to things we can’t avoid, such as the viruses that cause hepatitis B, hepatitis C or human papillomavirus infection, or by certain chemicals or environmental toxins. Most cancers start when abnormal cells start to grow and divide without stopping or dying as they should. These abnormal cells can also spread into nearby tissues and damage or destroy them. As the cancer continues to grow, it may form a lump or tumour. Cancer cells can also move to other parts of the body through the blood or lymphatic system. This process is called metastasis. The immune system is a group of cells and organs that work together to protect the body against infections and diseases. It’s made up of a network of cells and organs including the spleen, thymus, tonsils and lymph nodes in the neck. The lymphatic system consists of the ducts that run from the lymph nodes to the bloodstream and the blood vessels that carry fluid in between the tissues. A person’s chances of developing cancer are partly down to their genes and family history. But there are many other things that can increase the chance of developing cancer, such as smoking and a diet low in fruits and vegetables, being overweight or not enough physical activity, drinking alcohol, and exposure to ultraviolet radiation from sunlight or tanning beds. About 4 in 10 cancers are caused by preventable factors. Some cancers, such as leukaemia and some lymphoma, begin in blood cells and don’t form solid tumours. But most cancers start in cells that line blood vessels, muscles and other tissue throughout the body. Some cancers also form in the bone marrow, the soft spongy area inside most bones. These types of cancers are called non-solid tumours or hematologic cancers.

Medical is the study or practice of health care, including disease prevention and treatment. There are many branches of medicine, some focused on specific organ systems or diseases, others addressing general well-being. Most of the fields are multidisciplinary, with some overlapping between specialties. The term “medical” can also refer to the body of knowledge that physicians acquire during their education and training, which is typically structured through a doctorate in medicine or medical science, abbreviated MD or MS (in the United States) or Doctor of Osteopathy (DO, unique to the United States). Medical professionals must know a great deal about biology and chemistry in order to diagnose and treat patients effectively. Other essential components of medical knowledge include physics, mathematics and statistics. Many terms have roots in Latin or ancient Greek, and are derived from words that mean “to heal.” In addition to the scientific terminology that healthcare professionals must learn, there is also a vocabulary of common medical terms that has become part of our everyday language. A good place to start learning these terms is a medical dictionary. During a medical encounter, a physician meets with a patient to assess their symptoms and history and to recommend treatment options. This visit is documented in the medical record. Generally, the patient’s presenting complaint is noted as the chief complaint or CC. Other information recorded includes the patient’s past medical history (PMH) and family history. A number of key developments have occurred in the development of medical thinking throughout the ages. For example, a significant shift took place in the 14th and 15th centuries as scientists like Galen and Vesalius improved upon or rejected many of the theories that had been passed down from the previous generation of medical practitioners. The medical field also incorporates many ethical concepts, such as respect for persons – the principle that patients and their families have the right to be treated with dignity. This is also reflected in the concept of informed consent, which ensures that a patient understands the nature of a proposed course of action and has the opportunity to ask questions before agreeing to it. Most medical specialties fit into one of two broad categories: internal medicine and surgery. The majority of subspecialties within internal medicine require a preliminary degree in medicine, and in the United Kingdom, this is demonstrated by a Membership of the Royal College of Physicians (MRCP). The specialty of neurology addresses disorders of the nervous system, while obstetrics and gynecology are concerned with childbirth and the female reproductive and associated organs. Pharmaceutical medicine is the field of medical science that deals with the discovery, research, development, evaluation, registration and monitoring of medicines. Physiotherapy and rehabilitation, or physiatry, is aimed at improving function after injury or illness. Addiction medicine focuses on addiction and psychotherapy. Aerospace medicine is a branch of medical sciences pertaining to aircraft and space flight. Other less traditional or newer branches of medicine include clinical pharmacology and forensic medicine.

Health is the state of being physically, mentally, emotionally and socially well. It is also a process of becoming more resilient to cope with life’s challenges. Health is a complex concept that includes many different factors that are influenced by the interactions of genetics, lifestyle choices, and the environment. For centuries, people have viewed health in various ways depending on their culture and beliefs. For example, in ancient Greece, the idea of health was connected to a balance between body and soul and the harmony of the universe. Later, Hippocrates explained health as a product of lifestyle and environmental factors. This view was largely reinforced by the development of modern medicine and science. In the 20th century, the World Health Organization (WHO) defined health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. This definition has shaped the way we think about health today. It emphasizes the importance of promoting and protecting people’s health in order to achieve their full potential. Achieving and maintaining good health involves making choices that influence how our genes, bodies, emotions, and social and work environments interact with each other to affect our overall wellbeing. Some of these choices are under people’s control, such as their diet and exercise habits. Others are not, such as genetic disorders. Some are a result of the social and economic conditions in which people live. These are known as health determinants. People’s health is impacted by their daily routines, including the types of jobs they do and how much time they spend on leisure activities. For example, sedentary jobs such as office work can lead to obesity and back pain. Other work-related issues include a lack of sleep, stress and overwork. In the future, health will be increasingly understood in terms of a person’s resilience to coping with change and adversity. This is reflected in the fact that the word health comes from the old English haelth, meaning ‘wholeness’. It is therefore important to consider all aspects of health when attempting to define it. This will help us move away from the simplistic and reductionist approach to health that has been so prevalent in the past. The WHO definition of health is a significant step in this direction.

Pharmacy is a profession that deals with the preparation and dispensing of medications. It also specializes in the right way to use, store, and preserve medicine as well as letting patients know about side effects and other health care issues. Pharmacy professionals work in a variety of settings, including drugstores, medical clinics, hospitals, and universities. Some even do research and testing for new medicines. There are many ways to become a pharmacist, including earning a doctorate degree in pharmacy (PharmD). Most programs include a clinical year that provides students with a wealth of experience and skills that can be applied to a wide range of patient-care scenarios. There are also residency programs that allow students to gain years of clinical expertise in a short period of time. The majority of pharmacy professionals work in the pharmaceutical industry but some also find employment with government agencies, hospitals, and other private healthcare organizations. Many countries have laws that regulate the practice of pharmacy. In some cases, pharmacists must obtain a license to practice. The laws may vary by country but there are some common requirements. For example, pharmacies must be licensed to dispense prescription drugs and sell over-the-counter medicines. In addition, they must maintain a clean environment and follow strict storage requirements. Pharmacists are qualified to perform simple health care procedures, including taking a patient’s blood pressure and temperature. They can also diagnose everyday ailments, such as colds, the flu, aches and pains, and rashes. They can then recommend the correct treatment or advise a patient to see a doctor. In some cases, a pharmacist can provide a patient with a free sample of medicine. Pharmacy is considered a knowledge-based profession and has the reputation of being one of the most trustworthy and reliable sources for health advice. However, the challenge is how to translate formal professional knowledge into practice and use it to benefit patients. This can be done by applying the theory of knowledge production as developed in the book “Re-thinking Science.” It is also important to remember that pharmacy is not just about medicine. It is also about the social context in which the information is conveyed and the practical strategies used to promote compliance. For example, formal knowledge of respiratory disease is of little value if a patient does not know how to properly use her inhaler. The proposed model for pharmacy is a starting point to increase the clarity of definition and consistency in terminology that describe the pharmacy sector, regardless of country context. The idea is that it can serve as a platform for future discussion and debate on the pharmacy sector. It could also be a basis for multicountry comparisons of policy interventions. In the case of the pharmacy sector, there is an urgent need for a framework that defines the different dimensions of the industry. This would enable the development of consistent policy-making that is informed by a better understanding of what pharmacy is and how it functions.

Cancer is a group of diseases that starts when cells grow out of control and form a mass (tumour). There are many different types of cancer, but they all start in cells. Normal cells need to grow and make copies of themselves in a controlled way so they can develop into different tissues and organs. But sometimes a change happens (mutation) in the genes that tell cells how to grow and copy themselves. This can cause cells to go haywire and start growing and making more cancer cells or to spread to other parts of the body. It takes about six mutations to turn a normal cell into a cancer cell. Mutations can happen because of things that happen inside your body, such as exposure to radiation or chemicals in tobacco smoke. They can also be caused by things from outside the body, such as viruses or pollution. Mutations can also be inherited, which means you have a fault in one or more of your genes and are more likely to get a particular type of cancer. When a cancer is diagnosed, doctors can use tests to check if you have the right mix of cells to be cancerous and to see how quickly the cancer is growing. They can then recommend treatment to control the cancer or treat any symptoms that are causing them. Some cancers are more common than others, but many cancers are preventable. The biggest preventable causes are things you can control, such as not smoking or drinking too much alcohol and eating a healthy diet with plenty of fruit and vegetables. You can also protect yourself from some cancers by getting vaccinated. For example, the human papillomavirus (HPV) vaccine helps prevent cervical and other genital cancers and the Hepatitis B vaccine can help reduce your risk of liver cancer. The first signs of cancer can be anything from a painless lump in your breast to a persistent cough or a sore that won’t heal. If you notice any of these, make an appointment with your doctor. Tell your doctor how long you have had the symptom and how often it has happened. They will ask you questions about your general health and may do some tests to figure out what is causing it, such as blood tests or an ultrasound scan. They may also refer you to a specialist or take a biopsy.
