Most of what I read on pubmed says hops and its chemicals have anticancer properties.

Here's a free review on hops: https://www.thieme-connect.com/products/ejournals/html/10.1055/s-0032-1328330 In the section "Clincal Data" says usually ER-alpha agonists cause cancer proliferation in the breast. And how hops is an ER-alpha agonist. It also says In silico (computer model) a few chemicals from hops might have a potential to be hepatotoxic (hard on the liver).

The abstract in http://www.ncbi.nlm.nih.gov/pubmed/15231405 says how (Xanthohumol) XN from hops is anticancer.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1852439/ a mention of anticancer properties.

http://press.endocrine.org/doi/pdf/10.1210/jcem.85.12.7168 (last two paragraphs) says chemicals from hops have anticancer properties. Then it also says "The potential for adverse effects (e.g. in relation to fertility and hormone related cancer) must be considered." Its true, but people have taken that quote out of context about cancer.

http://www.ncbi.nlm.nih.gov/pubmed/17372274 is about topical application. See the "Discussion" section.

Did you see that in wikipedia, pubmed, a commercial site?

Do a search on pubmed, or pmc. Search humulus, xanthohumol, prenylflavonoids, 8-prenylnaringenin or other chemicals. use quotes and/or "AND" to refine your search. Reviews are an overview of many studies.

But yes, everything must be done with precaution, and do more research on all the aspects of hops.
