(NEW YORK) -- A new study suggests the cancer drug Herceptin reduces risk of breast cancer reappearing, according to HealthDay.
The four-year study, which was conducted in Milan, studied over 5,000 women with early-stage breast cancer from nearly 40 countries. The statistics show Herceptin reduced recurrence by 24 percent, HealthDay reports.
The patients took Herceptin after chemotherapy treatment for a year. Doctors are still not sure what the most effective period for Herceptin is in cancer treatment.
