Hi Curlywurly1
Thanks for your post.
It’s understandable that you want to know if the guidance on the duration of zoledronic acid after primary breast cancer has changed, and that you are concerned about the impact on your future health. As @Luskentyre1 says, it’s reasonable that you are seeking further clarification and have spoken with PALS.
Zoledronic acid is given to reduce the risk of breast cancer coming back and can support bone health. It is usually given 3 monthly for 2 years or 6 monthly for 3 years. The NICE guidance was last updated in April 2025 and no changes were made to the recommendations on bisphosphonates at this time.
You say that you initially had 4 infusions over 2 years. As it would be usual to have had 6 doses over this time, this may be why you were advised that you needed a further year of treatment, but as @Glebel mentions, we would suggest you speak to your breast care nurse or treatment team again to try and get further clarification.
As you have a family history of osteoporosis, you may also find our information looking after your bones helpful.
