Metronomic chemotherapy is the practice of giving low doses of drugs on a regular basis, rather than high doses all at once (as happens in injectable chemotherapy done in the clinic). The goal of metronomic chemotherapy is to keep the tumor from building new blood vessels, effectively cutting it off from oxygen and nutrition. The result may be the tumor stops growing, and some tumors will shrink. The advantage of metronomic chemotherapy is that it’s given at home, and side effects are generally lower than traditional chemotherapy. Metronomic chemotherapy is not used for every cancer type or diagnosis but may be an option you hear about for your dog’s case.
