Cancer-fighter Avastin just came up short as a treatment for ovarian tumors.
Two studies found that the drug, which blocks the formation of new blood vessels, didn't extend the lives of patients with ovarian cancer.
Avastin did slow the progression of the cancers a little bit. But the patients getting Avastin as part of treatment with several medicines had more side effects, including blood clots and high blood pressure, than the people who didn't get it.
