Tumors Grow Faster Without Blood-supply Promoting Molecule

Dense networks of blood vessels thought to spur cancer's growth could actually hinder rather than promote tumor progression. The findings partly explain why drugs designed to treat cancer by strangling its blood supply have been disappointing when used alone and why those treatments are more effective when combined with traditional chemotherapy. Despite their rapid progression, tumors fed by more normal vascular were also more vulnerable to the effects of standard chemotherapy drugs.
