So now that vaccine poisoning has been debunked, people have moved onto other conspiracies. I'd like to find a legitimate medical journal, and not a half-baked rag, present a clinical trial with evidence showing that folic acid increases cancer. (Which cancer, btw?) I have not heard of any, nor would any make sense. Folic acid is a vitamin, essential for replication of nucleic acids, whose deficiency would cause anemia, among other things. Relative deficiency of folic acid in pregnant women has been found to cause neural tube defects in neonates, which is why it is recommended as a supplement.
Offspring of Female Rats Given Folic Acid Supplements Develop More Breast Cancer, Study Suggests
The original study is in Cancer Research (impact factor 7.5)
Like I said, the folate/cancer story is an interesting one.
Alternatively

found no detectable effect on cancer rates after 5 years.
The source of a chemical has no bearing on its properties, when it is the same substance.
