Hello, I have ovarian cysts and a large one (10cm) on one ovary for which I have an appointment for in a couple of weeks.
I have been put on Tamoxifen, which I’ve read can cause cysts and polyps as a side effect. When I asked about other alternatives I was told they may have worse side effects. I’m still not convinced this is the best option for me.
Any advice please?

Hi zara_xo
Thanks for your post.
It sounds as though you are having a difficult time knowing whether tamoxifen is the best option for you.
As you mention, tamoxifen can affect the lining of the womb, and cysts and polyps are listed as potential side effects. As you have an appointment for ovarian cysts coming up, it may be worth asking during your appointment, whether it is safe for you to continue taking tamoxifen…
Tamoxifen is a hormone therapy drug used to treat oestrogen sensitive breast cancer in both premenopausal and postmenopausal women. Other hormone therapy drugs called aromatase inhibitors do exist, however, they can only be given to those who have gone through a natural menopause. You do not mention whether you have gone through the menopause. If you are pre or peri-menopausal you would also require ovarian suppression injections such as gosrelin if you were to take an aromotase inhibitor.
As with all drugs, aromatase inhibitors can cause side effects. Everyone reacts differently to drugs, so it’s not possible to predict how any drug will affect an individual. Do speak with your breast care nurse or treatment team as they would be able to explain whether this is an option for you based on your individual situation.
