In the late 19th century, the development of better microscopes not only helped document and define disease-causing organisms, but also made possible the examination of cells and cellular activity.
Study of cancer tissues and tumors revealed that cancercells were markedly different in appearance than normal cells of surrounding tissue or the cells from which they originated. Researchers began to focus on questions such as the origin of cells and the relationship of disease to the behavior of a cell.
It was the invention of the microscope that revealed the cancer cell itself. The early 20th century saw great strides made in understanding the structures, functions and chemistry of living organisms. Cancer research in cell culture , chemical carcinogens, diagnostic techniques and chemotherapy firmly established oncology as science.
Researchers pursued different theories of the origin of cancer, subjecting their hypotheses to systematic experimentation. A viral cause of cancer in chickens was documented in , and both chemical and physical carcinogens were conclusively identified. Chromosomal abnormalities were also investigated as possible causes of cancer. In , a need to combat rising public fear and ignorance concerning cancer led to two significant events: the publication of the first known article on cancer's warning signs in a popular woman's magazine, and formation of a nationwide organization dedicated to public education on cancer.
Cancer, as a disease, was brought into the light of day. This laid the foundation for scientific oncology, the study of cancer. The famous Scottish surgeon John Hunter suggested that some cancers might be cured by surgery and described how the surgeon might decide which cancers to operate on.
A century later the development of anesthesia allowed surgery to flourish and classic cancer operations such as the radical mastectomy were developed. The 19th century saw the birth of scientific oncology with use of the modern microscope in studying diseased tissues.
Rudolf Virchow, often called the founder of cellular pathology, provided the scientific basis for the modern pathologic study of cancer. Have you ever wondered when cancer was first discovered? When we hear about some of the causes of cancer, it may seem as if cancer is a recent ailment. Yet we've been learning that cancer has afflicted people for centuries, and as far back as the written word.
Let's take a look at some of what we know about the history of cancer, and how both the ideas of causation and treatments have changed over time. The word "cancer" came from the father of medicine: Hippocrates, a Greek physician. Hippocrates used the Greek words carcinos and carcinoma to describe tumors, thus calling cancer "karkinos.
Although Hippocrates may have named the disease "cancer," he was certainly not the first to discover the disease. The history of cancer actually begins much earlier. The world's oldest documented case of cancer hails from ancient Egypt in BC.
It was treated by cauterization, which destroyed tissue with a hot instrument called "the fire drill. There is evidence that the ancient Egyptians were able to tell the difference between malignant and benign tumors. In Ancient Greece, much less was known about the human body than what is known today, of course. For example, Hippocrates believed that the body was composed of four fluids: blood, phlegm , yellow bile , and black bile.
He believed that an excess of black bile in any given site in the body caused cancer. This was the general thought of the cause of cancer for the next 1, years. Autopsies done by William Harvey in paved the way to learning more about human anatomy and physiology.
Blood circulation was discovered, opening the doors for more research on diseases. It wasn't until that autopsies were performed to research the cause of death in ill patients. Giovanni Morgagni of Padua was the first to do such autopsies.
The lymph theory developed in the 17th century, replacing Hippocrates' black bile theory on the cause of cancer. The discovery of the lymphatic system gave new insight into what may cause cancer.
