Indirectly: high folate (folic acid) levels have been shown to be assocaited with methylation of tumor suppressor genes which make the inciting factor more capable of inducing a malignant transformation. While the folate (folic acid) levels do not induce cancer they may allow an MMTV virus which could be associated with breast cancer to allow the transformation process to happen at a shorter period of time.

Not a link: Reference ranges are set so that several percent of healthy folks fall outside on either end. I would make no connection.
