Medicine is the science and practice of establishing the diagnosis, prognosis, treatment, and prevention of disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Medicine has been around for thousands of years, during most of which it was an art (an area of skill and knowledge) frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism. In recent centuries, since the advent of modern science, most medicine has become a combination of art and science (both basic and applied, under the umbrella of medical science). While stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science.

Prescientific forms of medicine are now known as traditional medicine and folk medicine. They remain commonly used with, or instead of, scientific medicine and are thus called alternative medicine. As an example, evidence on the effectiveness of acupuncture is "variable and inconsistent" for any condition, but is generally safe when done by an appropriately trained practitioner. In contrast, alternative treatments outside the bounds not just of scientific medicine, but also outside the bounds of safety and efficacy are termed quackery. This can encompass an array of practices and practitioners, irrespective of whether they are prescientific (traditional medicine and folk medicine) or modern pseudo-scientific, including chiropractic which rejects modern scientific germ theory of disease (instead believing without evidence that human diseases are caused by invisible subluxation of the bones, predominantly of the spine and less so of other bones), with just over half of chiropractors also rejecting the science of immunization.

Henrietta Lacks (August 18, 1920 – October 4, 1951) was the involuntary donor of cells from her cancerous tumor, which were cultured by George Otto Gey to create an immortal cell line for medical research. This is now known as the HeLa cell line.

She was born as Henrietta Pleasant on August 18, 1920 in Roanoke, Virginia to Eliza (1886–1924) and John Randall Pleasant I (1881–1969). Eliza died giving birth to her tenth child in 1924. Sometime after his wife's death, John Pleasant took the children back to where their relatives on their mother's side lived, and where they were raised. In 1929, a 48 year old John, still living in Roanoke at 12th Street Southwest, married a 13-year-old girl named Lillian. John worked as a brakeman on the railroad.
