New chemo combo shows promise for breast cancer patients

This study tested different chemotherapy combinations and schedules for women with breast cancer that had spread to lymph nodes. The goal was to see if adding a drug called fluorouracil or giving chemo every 2 weeks (with a support drug to boost immune recovery) worked better than standard 3-week cycles. About 2,000 women took part, and researchers tracked how long they stayed cancer-free and any side effects.
