No, there are no scientific studies that link creatine as a causative factor in any form of cancer, any claims that link creatine to cancer are currently not validated by any evidence.

Creatine has even been shown in at least one human study (and several laboratory studies) to protect DNA from oxidative damage from various sources, such as exercise.[1][2][3]
