Cancer drug Avastin tied to 2 cases of flesh-eating disease in Canada
Health Canada issues caution to users, echoing U.S. warning

The cancer-treatment drug Avastin has been linked to 52 cases of flesh-eating disease worldwide, including one that resulted in death in Canada.
Health Canada issued a warning today in conjunction with the drug's manufacturer, Hoffmann-La Roche Ltd., echoing an earlier one from the U.S. Food and Drug Administration. It offered no specific details on two Canadian cases.
Avastin is used either alone to treat a particular type of brain cancer (glioblastoma), or in combination with chemotherapy to treat cancers that have spread to other parts of the body such as colon, rectal and lung cancer.
