Xeloda is used to treat cancer. It is pro-medication, it turns into a cytotoxic compound 5-fluorouracil (5-FU). 5-FU is formed in the tumors with help of thymidine phosphorylase, thus systemic influence of 5-FU on healthy tissues is minimal. The medication is used to treat breast cancer or colon or rectum cancer (also one with metastases) including types of the cancer resistant to paclitaxel and anthracyclines.
