Hello and thank you for your post.

I am afraid but there is no clinical guidance to reassure you that taking turmeric as a supplement (rather than in cooking in smaller quantities) while taking Letrozole is safe and beneficial.   As far as I know this has not been studied within a clinical trial. I think the best thing to do now is to ask your specialist breast cancer doctor if they would be ok with you taking it. I suspect there answer will be similar to mine.

When you look online you can see that there are a lot of different views on this so I just want to clarify that because they have been no clinical trials looking at this no one can say for sure that it is safe or beneficial to take alongside cancer treatment. 

I hope this has helped. Please get back to us if you need any more information or support.  You may find it helpful to talk things through with one of the nurses on our helpline.  The number to call is Freephone 0808 800 4040 and the lines are open from 9am till 5pm Monday to Friday.

Take care,

Caroline
