WebAngiogenesis is induced by cancer cells sending out a signal to cells of the blood vessels and stimulating them to grow. This process is crucial for the tumor to grow and spread throughout the body. An example of this Hallmark of Cancer can be seen with breast cancer. WebAngiogenesis, the growth of new capillary blood vessels, is central to the growth of cancer. An understanding of the cellular and molecular basis of tumor angiogenesis is therefore important for clinicians who diagnose and treat cancer by whatever modalities. WebLike healthy cells, cancer cells can't live without oxygen and nutrients. So they send out signals called angiogenic factors. These encourage new blood vessels to grow into the tumour. This is called angiogenesis. Without a blood supply, a tumour can't grow much bigger than a pin head. list of hottest pepper
