Eat your brocoli (more articles)

Recent articles on sulforphane (found in cruciferous vegetables  such as broccoli, cauliflower and cabbage) and also available as a nutritional supplement, and its effect on cancer:

Colon cancer (in vitro, abstract only): https://www.ncbi.nlm.nih.gov/pubmed/30041241

A high expression of prostaglandin E2 (PGE2) is found in colorectal cancer. Therefore, blocking of PGE2 generation has been identified as a promising approach for anticancer therapy. Sulforaphane (SFN), an isothiocyanate derived from glucosinolate, is used as the antioxidant and anticancer agents. . . SFN anticancer effects are associated with antiproliferative, antiangiogenic, and antimetastatic activities arising from the downregulation of the COX-2/ mPGES-1 axis.

Full recent article on urological cancer, but has more details about the action and potential use of sulforaphane: https://www.cancerletters.info/article/S0304-3835(18)30475-0/fulltext

Several epidemiologic and clinical studies have documented chemopreventive properties of SFN, making it an interesting candidate for additive cancer treatment. SFN shows remarkable anti-tumor effects in vitro and in vivo without exerting toxicity.

And for good measure, an article that says the type of fat you consume does not really matter: https://www.ncbi.nlm.nih.gov/pubmed/30038051

Neither total, nor major types (animal, vegetable, saturated, monounsaturated, polyunsaturated, trans), of dietary fat consumed after colon cancer was associated with cancer recurrence or survival.
