How cancer can spread

Cancer cells can be carried in the bloodstream or lymphatic system to other parts of the body. There they can start to grow into new tumours.

The Biology of Cancer

The oldest descriptions of cancer were written in Egypt as early as 3000 B.C., as part of an ancient Egyptian textbook on surgery. The name, "cancer" comes from the Greek word carcinos, which means crab. Hippocrates used this term to describe the disease because of the projections of a cancer invading nearby tissues. During the 16th century, when the theory of bodily humors prevailed, it was believed that an excess of black bile caused cancer. The renowned anatomist Andreas Vesalius searched diligently for this black bile and ultimately discarded the this theory when he was unable to find it. In 1838 a botanist named Matthias Schleiden and Theodor Schwann, a physiologist, proposed that all living things were composed of fundamental units called cells. Shortly after the introduction of this idea, Virchow (the "father" of pathology) proposed that cells only arose from other cells and that growth could only occur as a result of hypertrophy or hyperplasia. Virchow studied cancers under with a microscope and recognized that they represented hyperplasia in an extreme form that he dubbed "neoplasia."

Cell Division, Cancer | Learn Science at Scitable

Cancer is somewhat like an evolutionary process. Over time, cancer cells accumulate multiple mutations in genes that control cell division. Learn how dangerous this accumulation can be.

Asthma: pathogenesis and novel drugs for treatment

Asthma affects almost 20 million people in the United States and more than 300 million people worldwide. Of these, 10-15% have severe asthma, which is refractory to commonly available drugs. New drugs are needed because those that are currently available cannot control symptoms and exacerbations in all patients and can cause adverse reactions. In the past 10 years, there have been substantial advances in the understanding of asthma genetics, airway biology, and immune cell signaling. These advances have led to the development of small molecule therapeutics and biologic agents that may improve asthma care in the future. Several new classes of asthma drugs—including ultra long acting β agonists and modulators of the interleukin 4 (IL-4), IL-5, IL-13, and IL-17 pathways—have been evaluated in randomized controlled trials. Other new drug classes—including dissociated corticosteroids, CXC chemokine receptor 2 antagonists, toll-like receptor 9 agonists, and tyrosine kinase inhibitors—remain in earlier phases of development. Despite some preliminary efficacy data, there is insufficient evidence to make strong recommendations about the use of these newer agents. Future research on the clinical efficacy of these biologic agents, the effect of newer agents on severe asthma in pediatric patients, and the biology of non-eosinophilic and corticosteroid resistant asthma is needed to reduce the morbidity of asthma worldwide.

Extraembryonic Mesoderm - Embryonic Development & Stem Cells - LifeMap Discovery

The extraembryonic mesoderm in human embryos is believed to form from the hypoblast (although trophoblast contribution is also plausible), while in mouse, it arises from the caudal end of the primitive streak.
