@susan7656 Hi, It "s interesting to read your article. I had dense breasts, Also used collage for many years. In Aug. 2024 I was diagnosed left side breast cancer and in Nov 2024 I had a mastectomy. I was 68 year old. I didn't request a reconstruction. My Onco Score was 22. No chemo needed. My tumor was ER+PR+Her2- . I am on Letrozole for 5 year.
I quit taking the collagen after the diagnosis. Now I am taking Naked Whey Protein and AlgaeCal approved by my oncologist. Sometime I blame myself that I should do more research with collagen. But most of the time. I don't feel sorry for taking it. There is no evidence to prove the collagen can cause the cancer.
