I am glad you raised this question. I am going to follow up with my oncologist. I had dense breasts, used collagen for years and developed breast cancer in Sept 2024 with a mastectomy in Oct 2024. I’m undergoing reconstruction.

Although the chance of my breast cancer returning is quite low, and although my particular type of breast cancer rarely metastasizes, I am quite curious if the collagen powder supplements I take could be putting me at some type of risk.

I think this is an important topic for so many women who are in survivorship or dealing with breast cancer treatment.

Several prominent social media influencers (who are doctors) who promote collagen use and other supplements do not address the vast audience of breast cancer patients.

Of course we want strong bones. But I also do not want to do anything that promotes preventable cancer.
