Read our Colorectal Cancer research guide →This study is looking at how genetic differences in a specific gene affect how people tolerate capecitabine, a common chemotherapy drug used to treat breast and colorectal cancer. Researchers want to understand why some patients have more side effects from this medication than others. By studying your genes, they hope to help doctors better predict who might struggle with this treatment.
Cancer patients taking this medication experience different levels of side effects, and doctors don't yet have a good way to predict who will have trouble. This study aims to find a genetic marker that could help identify patients at higher risk, so doctors can adjust treatment plans accordingly.

This is an observational study, meaning researchers will simply monitor you while you receive your regular cancer treatment. You would likely have a blood sample taken so scientists can analyze your genes and look for the specific genetic marker they're studying. Your participation would involve sharing information about any side effects you experience from the medication, and researchers would track how your body responds during your regular cancer care visits.
