Study reveals microscopic interaction of cancer cells and blood vessels in tumor formation

Researchers documented the earliest steps of tumor formation in mice and rats, showing that cancer cells can grow new blood vessels when just hundreds are present. The study suggests that angiogenesis inhibitors might be useful at the earliest stages of tumor development to prevent recurrence and spread.
