Thank you for posting links to research! I will add to this discussion my experience. Sixteen years after my first diagnosis of stage 1 BC, lumpectomy, partial radiation and 5 years of tomixifen IT has returned. This diagnosis is also stage one but with more aggressive properties. Coincidentally, two years ago I started each day (for roughly 16 months) with a smoothie infused with a collagen supplement. And I do (did) have dense breast. I’d say to all BC patients, don’t take it!

My reading of the Collagen III study seems to suggest that collagen III(Col3) can aid in suppressing breast cancer - "suggest that strategies that increase Col3 may provide a safe and effective modality to limit recurrence in breast cancer patients." This is very confusing...seems like certain type of collagen is good for breast cancer while other types are bad...
