Vitamin B12 tested to stop Chemo's painful skin side effect

This study is testing whether a form of vitamin B12 (mecobalamin) can prevent a painful skin reaction on the hands and feet caused by a common breast cancer drug, capecitabine. About 234 women with early breast cancer will be randomly assigned to receive either the vitamin B12 treatment or a placebo while taking their cancer medication. The main goal is to see if the treatment reduces the occurrence of moderate-to-severe hand-foot syndrome, potentially allowing patients to continue their full cancer treatment without painful interruptions.
