Mesothelioma, a form of cancer caused by asbestos exposure, is reported to be the deadliest of all work-related respiratory illnesses in the United States. As with other forms of cancer, chemotherapy and surgery are frequently used as a form of treatment although no cure has been found. more »
Turmeric is a naturally occurring spice that has also been experimented with as a treatment for a variety of disorders, including cancer. The spice is normally found in curry as a coloring agent. Turmeric has been believed to be able to treat a multitude of health issues from depression to cancer, but has only been validated to be... more »
Tamoxifen, otherwise known as Nolvadex, is a cancer treatment and preventative drug that is specifically used for the treatment of breast cancer in its early stages. Tamoxifen is used for both men and women in the treatment of estrogen receptor cancers that are positive such as those involved in breast cancers. Tamoxifen is the most... more »
Blood vessels are an integral part of the circulatory system. These components assist in the transportation of blood within the body, often in and out of the heart. There are three basic types of blood vessels: the capillaries, which exchange water and chemicals between the blood and tissues; the arteries, which carry blood away from... more »

Angiogenesis is a physiological process involving the growth of new blood vessels from pre-existing vessels. Though there has been some debate over terminology, vasculogenesis is the term used for spontaneous blood-vessel formation, and intussusception is the term for new blood vessel formation by splitting off existing ones.
Angiogenesis is a normal and vital process in growth and development, as well as in wound healing. However, it is also a fundamental step in the transition of tumors from a dormant state to a malignant one. The identification of an angiogenic diffusible factor derived from tumors was made initially by Greenblatt and Shubik in 1968."greenblatt">Greenblatt M, Shubik,P, "Tumor Angiogenesis: Trans filter diffusion studies by the transparent chamber technique", J.

Sprouting angiogenesis
Sprouting angiogenesis was the first identified form of angiogenesis. It occurs in several well-characterized stages. First, biological signals known as angiogenic growth factors activate receptors present on endothelial cells present in pre-existing blood vessels. Second, the activated endothelial cells begin to release enzymes called proteases that degrade the basement membrane in order to allow endothelial cells to escape from the original (parent) vessel walls. The endothelial cells then proliferate into the surrounding matrix and form solid sprouts connecting neighboring vessels. As sprouts extend toward the source of the angiogenic stimulus, endothelial cells migrate in tandem, using adhesion molecules, the equivalent of cellular grappling hooks, called integrins. These sprouts then form loops to become a full-fledged vessel lumen as cells migrate to the site of angiogenesis. Sprouting occurs at a rate of several millimeters per day, and enables new vessels to grow across gaps in the vasculature. It is markedly different from splitting angiogenesis, however, because it forms entirely new vessels read more at » http://en.wikipedia.org/wiki/Angiogenesis
