Collagen and cancer tumors?

I’ve been taking powdered collagen supplements for my skin and hair for a couple of years now. My hair grows like crazy! My understanding is that ingesting collagen can actually make the body produce more collagen. I recently ran across an article by Ray Peet (The Cancer Matrix) that said there is a definite link between collagen and cancer tumors. "In general, substances that increase collagen production are promoters of cancer and contribute to the progression of heart failure, and other degenerative changes.” Does this mean that collagen supplements could be promoting some types of cancers? Should we all stop taking collagen supplements immediately? Please advise.
 
I haven't read that article in a while. I think Ray was referring to factors that increase local endogenous collagen tissue. Eating collagen per se provides balancing amino acids and Ray has positively spoken of the importance of consuming dietary collagen in amounts quite high.

I’ve been seeing studies that suggest that ingesting collagen causes the body to make collagen. That is why people are taking collagen supplements for their skin and hair.
 
I think it's similar to calcium in a way. Yes, the calcium you consume aids in structure and function, but not consuming it can cause hypercalcemia under the effect of PTH. Consuming collagen probably will just be utilized as needed. Not consuming it will lead to an imbalance in the amino acid profile and probably demand it be supplied from tissue under the effect or adaptive hormones.
