Bevacizumab is an injectable antibody that is used to treat certain types of cancer. It is often used to treat breast cancer, colorectal cancer, brain cancer, and some types of lung and kidney cancer. This antibody attacks and kills cancer cells in order to reduce and eliminate cancer.
Patients who use this drug are at increased risk for gastrointestinal perforation, a condition where they develop holes in their gastrointestinal system. This condition is more likely with colorectal cancer than other types of cancers, although it can occur any time a patient uses Bevacizumab. Patients who develop this condition suffer from severe stomach pain and nausea. The medication must be permanently discontinued if the patient develops this condition, as gastrointestinal perforation can be fatal.
