We have had some success with flax and prostate cancer. It makes sense that it can help ovarian cancer as well. As an interesting coincidence, the Budwig diet has flax as a key component.
"A 2010 study published in the journal Gynecological Oncology found that hens fed with a 10% flaxseed-enriched diet for 1 year had "a significant reduction in late stage ovarian tumors," as well as "overall better health and reduced mortality." The study authors concluded "These findings may provide the basis for a clinical trial that evaluates the efficacy of flaxseed as a chemosuppressant of ovarian cancer in women."
More recently, a study published this year in BMCGenomics looked deeper into the possible molecular mechanisms involved in flaxseed's anti-tumor properties in ovarian cancers. Researchers used a "bioinformatic" approach by analyzing the pattern of gene expression in ovarian tumors, identifying which genes are up-regulated when tumors form and which are suppressed when the hens are fed a 10% flaxseed diet.
Interestingly, they found that "a group of highly up-regulated genes that are involved in the embryonic process of branching morphogenesis [note: embryogenesis and carcinogenesis share similarities]," were reduced 40-60% in flaxseed fed hens. Moreover these 'cancer associated' changes in gene expression corresponded with increases in two specific cancer-associated biomolecules -- E-cadherin and miR200 – both of which were decreased 60-75% in tumors from flax-fed hens.
The study authors concluded "CONCLUSIONS: We suggest that nutritional intervention with flaxseed targets the pathways regulating branching morphogenesis and thereby alters the progression of ovarian cancer."
