I have had breast cancer twice, once in 1989 and then in 2009.

I have had breast cancer twice, once in 1989 and then in 2009. The first time I had radiotherapy followed by tamoxifen. The second time (a new tumour) I had radiotherapy, chemotherapy, Herceptin therapy (my HER2 test was positive) and am now on Anastrozole.
Somebody mentioned photo-oestrogens in food, such as flax seeds. Can these have an adverse effect on my given my history?
Hello from JustAnswer.

The evidence about phytoestrogens is mixed. There is some evidence that they offer some protection against cancer, but the studies are not consistent. There certainly is a strong theoretic risk of taking any substance that has estrogenic activity in someone with a history of breast cancer.

At the present time, most doctors would advise breast cancer survivors to avoid large amounts of foods that contain phytoestrogens. Eating some of these foods as part of a varied diet is probably not an issue, but eating a significant amount of these foods to try to ingest large amounts of phytoestrogens would at least carry a theoretic risk.

I also typically advise my patients to avoid large ingestion of phytoestrogens until the clinical evidence is more clear.

If I can provide any further information, please let me know.
