Cancer Drugs Make Tumors Grow

E-mail Print PDF

Drugs like Avastin that are used to treat some cancers are supposed to work by blocking a vessel growth-promoting protein called vascular endothelial growth factor, or VEGF. With VEGF held in check, researchers have assumed tumors wouldn't generate blood vessels and that should keep malignancies from growing. In a sense, the cancerous growths would be "starved". But new research just published in the journal Nature shows this isn't true. Instead of weakening blood vessels so they won't "feed" malignant tumors, these cancer treatments, known as anti-angiogenesis drugs, actually normalize and strengthen blood vessels -- and that means they can spur tumors to grow larger.
