Angioworld
Almost all tissues develop a vascular network that provides cells with nutrients and oxygen and enables them to eliminate metabolic wastes. Once formed, the vascular network is a stable system that regenerates slowly.

The angiogenic process, as currently understood, can be summarized as follows:
Angioworld
The normal regulation of angiogenesis is governed by a fine balance between factors that induce the formation of blood vessels and those that halt or inhibit the process. When this balance is destroyed, it usually results in pathological angiogenesis which causes increased blood-vessel formation in diseases that depend on angiogenesis.

A New Perspective on Cancer
The way we think of a disease has profound implications in terms of its treatment. The concept of cancer as a monolithic terminal illness raised the hope of “winning the war on cancer”. This idea has led to the development of successive generations of weapons used at their maxi- mum tolerated dose. While the strategy appears useful in prolonging survival, complete remission remains a rare event. This is because even if only one single enemy is spared, it can still raise an army of new, now resistant, cancer cells that can strike again in a fatal breaking wave.
As the long hoped for idea of a universal cure for cancer fades away, a new vision of multidisciplinary complemen- tary approaches emerges and opens the door to mixed protocols that combine alternative therapies with more conventional cancer treatments.

Angiogenesis in cancer
How angiogenesis complicates cancer
Angiogenesis performs a critical role in the development of cancer. Solid tumors smaller than 1 to 2 cubic millimeters are not vascularized. To spread, they need to be supplied by blood vessels that bring oxygen and nutrients and remove metabolic wastes. Beyond the critical volume of 2 cubic millimeters, oxygen and nutrients have difficulty diffusing to the cells in the center of the tumor, causing a state of cellular hypoxia that marks the onset of tumoral angiogenesis. New blood vessel development is an important process in tumor progression. It favors the transition from hyperplasia to neoplasia i.e. the passage from a state of cellular multiplication to a state of uncontrolled proliferation characteristic of tumor cells. Neovascularization also influences the dissemination of cancer cells throughout the entire body eventually leading to metastasis formation.The vascularization level of a solid tumor is thought to be an excellent indicator of its metastatic potential.

Physiological and pathological angiogenesis
However, pathological angiogenesis, or the abnormal rapid proliferation of blood vessels, is implicated in over 20 diseases, including cancer, psoriasis and age-related macular degeneration.
However, other factors have virtually no effect on the division of cultured endothelial cells or, in the case of TGF-beta and TNF-alpha, paradoxically inhibit their growth indicating that their angiogenic action is indirect.
