Angiogenesis, the growth of new capillary blood vessels in the body, has much more importance in healing and reproduction. The body controls angiogenesis as there is a natural balance between growth and inhibitory factors in healthy tissues.
When this balance is disturbed, the result is either too much or too little angiogenesis. Abnormal blood vessel growth, either excessive or insufficient, is now recognized as a "common denominator" underlying many deadly and debilitating conditions, including cancer, skin diseases, age-related blindness, diabetic ulcers, cardiovascular disease, stroke, and many others.
