Tamoxifen: What you should and shouldn’t avoid
Tamoxifen is a very typical hormone treatment for breast cancer patients, especially for those who are premenopausal and who are oestrogen receptor positive (ER+). However, what you may not know is that the effectiveness of tamoxifen can be altered, both positively and negatively, by certain food and drinks.
The drug tamoxifen works by blocking the oestrogen receptors on the outside of cancer cells, helping to reduce the cancer from growing any further. Once it enters the body, its efficiency is determined by how quickly it is converted into its active form called ‘endoxifen’. Some foods and drinks can help boost or hinder this conversion, thereby altering the effectiveness of the drug.
Foods like grapefruit and turmeric have been shown to reduce the effectiveness of tamoxifen, while there is growing evidence showing that green tea can in fact increase it.
